Concentrates in our definition include high-quality residues from the fertilizer industry, mining concentrates, and other high-quality powder free-flowing materials. Sweeps are oxide-based residues of all kinds that occur during cleaning, sweeping and other collection activities in a precious metal processing industry.
Slags include ceramic residues from thermal melting or casting processes which still contain traces of precious metals.
Sludges, by our definition, are aqueous residues typically on an oxide carrier, which would typically be precipitates from the wet treatment of materials containing precious metals, from exhaust air scrubbers, or from the process washing out of ores.
Crucibles consist of thermally resistant clay, graphite or other type of ceramics, used in the melting process of high-grade precious metal materials and contaminated with precious metal buildup after use.
Fireclay comes from the lining of refractories of melt shops contaminated with precious metal residues, for example from the metallurgical processes in the fiberglass industry.
When it comes to the pre-treatment, homogenizing, sampling and value determination of your materials, you benefit from the highest standards and the highest possible precision at MAIREC. Our effective, continuously improved systems and machines, some of which were developed in-house by our own engineers, allow us almost unlimited processing capacity.
