Precious metals are perhaps among the most recycled commodities on Earth, mainly because their value usually makes it worthwhile to spend time and effort to recover them. The process of recovering and refining precious metals has been around for a long time, but even today it remains somewhat of a 'hidden' industry.
Refining precious metals is an integral part of quality. It's a process that guarantees the safety and integrity of the final product. So, if you're interested in the technical side of metal processing, keep reading!

The purification process removes minor elements from the zinc sulphate solution prior to electrolysis. The purification is achieved by the addition of zinc dust (produced in the Casting Plant), promoting cementation reactions. As a result, impure metals are converted to the solid form and separated from the zinc sulphate solution by filtering.
Refining implies selecting one specific metal and isolating it, so as to obtain a certain degree of purity in the final output. We recover and refine gold, silver, cooper and platinum group metals such as palladium, platinum and rhodium. We own a robust and dynamic process plant that can satisfy the customers' demands.

Refining is the process of purifying an impure metal in metallurgy. It differs from other processes like smelting and calcining in that those two involve a chemical change to the raw material, whereas refining usually results in a final material that is chemically identical to the original one, only purer.
A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using required mineral processing solutions to liberate the valuable metals. The discarded tailings are then dewatered and dry stacked, and the water recycled within the plant or properly disposed back to nature.

When completed, the reduced lot is then shipped to the refinery for sampling, assaying, and final recovery and refining of its precious metals. Most hydrocarbon processing catalysts are sampled by a process known as dry sampling. Dry sampling involves use of mesh screens, vibratory feeders, rotary samplers, and other specialized equipment.
