Raw gold in.
Documented bar out.
Precision smelting for gold consolidation with full weight reconciliation and chain-of-custody records. What goes in is accounted for. What comes out is certified.
Smelting and refining are not the same service.
Understanding which one you need is the right first step.
Gold smelting is the process of melting raw or mixed gold material at high temperature to produce a consolidated, homogeneous form, typically a doré bar or cast bar. It removes physical impurities such as stones, sand, and other non-metallic material through the melting process, and it combines material from multiple sources into a single, unified form. The result is a consolidated gold material of known weight and approximate composition.
Gold refining goes further. Refining separates gold from metallic impurities at a chemical level, producing a certified output at a specific, verified purity. Refining requires smelting as a preparatory step, but smelting alone does not produce a refined, certified purity output.
For many clients, smelting is exactly the service they need, and a fully separate, complete service when conducted properly. A consolidator who is bringing together material from multiple sources needs a smelted output with accurate weight documentation and a chain-of-custody record before that material moves anywhere. A mining operation preparing a batch for export needs a cast bar with documented composition before the export documentation process begins. A dealer who wants to present material to a buyer in a standardised, professional form needs smelting, not refining.
At Maxmetal, smelting is not treated as a minor preparatory step. It is a full service with its own documented process, its own chain-of-custody standards, and its own output certificate. If you are not certain whether you need smelting, refining, or both, contact us before you come in. We will advise you directly based on what you have and what you need the output for.
Gold smelting at Maxmetal serves clients at every stage of the gold chain.

You need a smelted, cast output with documentation that satisfies pre-export requirements.
Maxmetal's smelting output is accompanied by weight certification, composition documentation, and chain-of-custody records built to support the export documentation process. What leaves our operation is prepared, documented, and ready for the next step.
Contact Our TeamGold smelting is the controlled process that turns raw material into consolidated, documented form.
Gold in its raw state, dust, grain, nuggets, alluvial material, mixed lots from multiple sources, is not yet in a form that most commercial transactions and export processes can work with efficiently. It cannot be weighed with the precision that a formal transaction requires. It cannot be presented to a buyer as a standardised, verifiable unit. And when it comes from multiple sources, it has no single chain-of-custody record that a buyer or compliance reviewer can follow.
Smelting resolves all of that. The process melts the raw material at precisely controlled temperatures, removes physical impurities through the melting process, and produces a consolidated output, typically in the form of a doré or cast bar, of known weight and documented composition. The output is a single, unified material that can be weighed accurately, presented professionally, and accompanied by documentation that traces it from intake to output.
At Maxmetal, the smelting process is conducted by trained personnel in a controlled environment, under documented procedures, with weight measurements taken before and after the process and full reconciliation of the difference. There are no unexplained losses. There are no undocumented transfers. From the moment your material enters our smelting process to the moment your cast output is handed to you, every stage is recorded.
The output certificate we issue for a smelting engagement documents the intake weight and composition, the smelting methodology, the output weight and form, and the chain-of-custody reference that ties the finished bar to the original material you brought in. If that output is going directly to a buyer, the buyer has a complete documentary record. If it is going on to the refining process, the refining chain-of-custody starts from a documented foundation.

From raw material to cast output.
The Maxmetal smelting process follows the same documented standard on every engagement. The material going in is known. The process applied is recorded. The output is weighed, documented, and returned with a complete paper trail.
Your material is received, sorted by source lot if applicable, and formally documented.
If your consignment consists of material from a single source, it is received and weighed as a single lot. If your consignment consolidates material from multiple sources, each source lot is documented separately at intake before smelting combines them. This separation at intake is what makes your consolidated output traceable back to its origins.
Your material is weighed on certified scales and assessed before the process begins.
The pre-smelt weight is the anchor of your weight reconciliation record. Every gram of input is recorded before the furnace is lit. If you have material that requires separation of non-gold components before smelting, stones, debris, non-metallic material, that separation is documented as part of the pre-smelt assessment.
Your material is smelted at controlled temperatures under documented procedure.
The smelting process is conducted in a controlled environment by trained Maxmetal personnel. Temperature, duration, and methodology are recorded as part of the process documentation. Physical impurities removed during the smelting process are documented as part of the weight reconciliation rather than treated as unaccounted loss.
The smelted gold is cast into the agreed output form and weighed on certified scales.
The output, typically a doré or cast bar, is weighed immediately after casting on the same certified scales used at intake. This output weight, compared to the pre-smelt input weight, forms the basis of your weight reconciliation report. The difference is accounted for completely before the process moves to documentation.
Your smelted output and complete documentation are returned to you.
Your cast output is presented alongside your smelting certificate, weight reconciliation report, and chain-of-custody record. If the output is proceeding to refining, the smelting documentation becomes the first stage of the refining chain-of-custody. If the output is going directly to a buyer or export process, it leaves Maxmetal with a complete paper trail from raw material to finished bar.
The input weight and the output weight
are different numbers.
Every gram of the difference is explained.
In a smelting process, the weight of the output is always lower than the weight of the input. This is not a discrepancy. It is the expected and documented result of removing physical impurities, losing trace moisture, and the physical realities of the melting and casting process. Every gram of that difference has a specific cause.
What makes Maxmetal's process accountable is that every gram of the difference is documented, not estimated, not approximated, not attributed to a general "processing loss" figure that the client has to accept on faith. Your weight reconciliation report breaks down the input weight, the documented removal of non-gold material, the documented processing margin, and the certified output weight. The arithmetic is complete. Every line adds up.
If your reconciliation report raises a question, bring it to us. We walk through every line with the documentation in hand. There is no figure on a Maxmetal reconciliation report that does not have a traceable origin. That is not a policy we adopted because clients asked for it. It is the standard we built the operation to.

Smelting is often one step in a larger process.
At Maxmetal, the chain is unbroken.
For many clients, smelting is not the final step in their engagement with Maxmetal. It is the step that prepares their material for what comes next, and the step that makes everything that follows more precise, more efficient, and more commercially defensible.
A mining operation that smelts its production at Maxmetal before moving it to refining starts the refining process with a material of known weight and documented origin. The refining chain-of-custody begins from the smelting record, not from a new intake, which means there is a single, unbroken document trail from raw material to refined, certified output.
A dealer who smelts consolidated lots at Maxmetal before presenting them to an export buyer goes into that conversation with a standardised, professionally presented material and a weight documentation record the buyer can verify. The buyer does not need to take the dealer's word for the input composition. The Maxmetal smelting record tells the story.
A client who is not yet certain whether they need refining after smelting does not have to decide before they bring their material in. We advise at intake based on the specific material and the client's commercial situation. The smelting process produces the information, the composition and weight of the output, that makes the refining decision a straightforward one.
Can also be final output, with documentation.
One chain of custody. No gaps between stages.
Smelting material from multiple suppliers.
Every source documented. One clean output.
For dealers and commercial operators who aggregate gold from multiple artisanal miners, small-scale operations, or separate purchase lots, the challenge is not just the smelting process itself. It is producing a consolidated output that is commercially clean, meaning that any buyer, export agency, or compliance reviewer can see exactly what sources contributed to the final material and in what proportion.
Without that documentation, a consolidated lot is commercially opaque. A buyer cannot verify its origin. A compliance review cannot confirm its chain of custody. And in international markets where responsible sourcing requirements are increasingly enforced, an opaque origin is a commercial liability regardless of the gold's actual quality.
Maxmetal's multi-source smelting process addresses this directly. At intake, each source lot is documented separately, the origin, the supplier, the weight, and the condition of the material at the point of receipt. Those separate source records are then consolidated into a single smelting record that traces the complete origin of the output bar back to every contributing lot.
The output certificate for a multi-source smelt contains the consolidated output weight and composition alongside a source documentation summary. A buyer receiving this material has the documentation to confirm not just what the output contains, but where every contributing lot came from. That is the difference between a commercially clean consolidated lot and one that raises questions.
If you are a dealer or consolidator whose buyers are beginning to ask harder questions about origin documentation, this is the service that gives you the answers before they ask. Contact us to discuss your specific consolidation requirements and we will confirm the documentation approach before your material comes in.
The questions we hear before a smelting engagement begins.
A doré bar is the output of the smelting process, a cast bar of mixed gold and silver content, with physical impurities removed. It is a consolidated, standardised form but its purity is not yet certified at a refined specification. A refined bar has been through the additional refining process to separate gold from all metallic impurities and produce a certified purity output. If you need a doré bar for a specific buyer or export process that accepts it, smelting is your service. If you need a certified purity output, you need refining, which may begin with smelting as a preparatory step.
Yes. Multi-source consolidation is a specific service we offer, and we handle it under a documented process that records each source lot separately before combining them. Your consolidated output comes with a source documentation summary that traces the origin of every contributing lot. If you are consolidating material from multiple sources, tell us at intake. The documentation approach is different from a single-source smelt and we need to set it up correctly from the start.
Both input and output weights are measured on certified scales. The difference between those two figures is documented in your weight reconciliation report, with every reduction attributed to a specific cause, removal of non-gold material, processing margin, or casting loss. There is no figure on your reconciliation report that is not explained. If any figure raises a question, we walk through the documentation with you before you leave.
It depends on the buyer's requirements. Some buyers accept doré bar output with weight documentation and chain-of-custody records. Others require refined, certified purity output before they will take delivery. We advise you on your buyer's likely requirements based on what you tell us about them at intake, and if you are not certain what your buyer will accept, we recommend clarifying that before the smelting process begins rather than after.
Not always, but it depends on what you need from the smelting output. If you are smelting material purely to consolidate it into a standard form for presentation or transport, a pre-smelt assay may not be required. If your buyer or export process requires a compositional certificate alongside the smelted output, a pre-smelt assay establishes the baseline for that documentation. We discuss this at intake and advise you on whether a pre-smelt assay is in your interest before we begin.
Non-gold material removed during the smelting process, slag, physical impurities, non-metallic matter, is documented as part of your weight reconciliation record. It does not disappear from the accounting. What remains of your original material after separation is weighed and documented. If there is any recoverable value in the separated material that warrants discussion, we raise it at that point. Nothing is discarded without it being part of the documented record.
Every smelting engagement at Maxmetal is conducted under active DGSM licensing and full regulatory compliance.
Our mineral refinery license is issued by Uganda's Directorate of Geological Survey and Mines and is independently verifiable through the MCRS portal. Our license reference appears on every smelting certificate we issue. If your engagement or your buyer's compliance process requires documentation of our regulatory standing, we provide it on request.
