Keywords: gold, silver, nickel, copper, cyanide leaching, activated carbon adsorption Introduction Gold is recovered from its ores hydrometallurgically by the cyanide leach process. The gold reacts with cyanide according to reaction (Davidson and Sole, 2007): Au0 +2CN– + .
· The inertness and high specific gravity of gold account for its concentration by mechanical processes as a heavy mineral in stream and beach environments (placers). Gold and silver are both mobilized by hydrothermal fluids as sulfide or chloride complexes, and precipitated in response to changes in solubility caused by decreasing temperature, or .

· This process is the first process from gold recovery. There are many kind of adsorbans that can be used, activated carbon, zeolit, or resin. Common adsorban in many gold processing industry is activated carbon. Several factor to choose activated carbon are: 1. Hardness/attrition resistant 2. Activity 3. Total gold capasity adsorption 4.
The Kell Process is the benchmark in efficient, lowenergy metals recovery with low environmental impact towards a sustainable carbonneutral, toxicfree mining operation. Kell Technology The Kell Process has been developed for extraction of platinum group metals (PGM), gold, silver and base metals from PGM sulfide flotation concentrates without smelting.

Gold and silver nanoparticles have been commonly used in different pharmacy appliions and drug delivery systems due to their inert nature, stability, high disparity, noncytotoxicity, and biocompatibility. This review highlights the synthesis and appliions of gold and silver nanoparticles in the field of pharmacy and drug delivery.
The process design of gold leaching and carboninpulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon, typically in a rotary kiln at temperatures of 650–750°C. Regeneration is carried out in a steam atmosphere to minimize carbon degradation due to oxidation.
· The gold, copper and silver concentrates are detached from carbon in a gravity and floatation circuit. The copper and silver concentrates are sold to smelters in China and Japan. The solution is transferred from adsorption tank to the tailing storage facility for reuse. Recovered gold is moved to the tailing thickener to generate gold precipitates.
· Cyanidation is the predominant process by which gold and silver are recovered from their ores in metallurgical operations, and it is recognized that the Carbon in Pulp, the Merrill–Crowe, the Ion Exchange, and Solvent Extraction processes are used for concentration and purifiion of gold and silver from cyanide solutions.
