Lime is used extensively in the recovery of gold and silver. Ores either run-of-mine milled autoclaved or roasted are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

Wet High Intensity Magnetic Separators WHIMS use electromagnetic coils to generate a very high magnetic force that can be implemented to allow separation of para-magnetic minerals. This technology also employs unparalleled high gradients within their exchangeable matrices to allow recovery of fine material down to 15 micron.
The type of mill and the circuit configuration are intrinsic to maximizing the grade and recovery profile of an ore. Metso Outotec offers both stirred milling technologies: Vertimill is a vertical grinding mill using gravity-induced technology and Stirred Media Detritor SMD is a fluidized vertical stirred mill.
Description. With over 50 years of experience Hayward Gordon are considered experts in their field and with installations around the world and across most mineral extraction processes Hayward Gordon have established a reputation for providing quality agitators / mixers you can depend on.
The slurry of gold-bearing leachate and solid residue leaving the leaching circuit contains in the range of 1–5 ppm gold and is directed to an RIP circuit where gold and copper are loaded onto a strong-base resin to ∼1–5 kg/t Au and ∼10–25 kg/t Cu. Copper is eluted from the resin using ammonia thiosulfate 200 g/L and gold is eluted
Bioleaching and mineral bio-oxidation are in commercial use today 1 in dumps to scavenge copper from run-of-mine rock; 2 in heaps to leach copper from secondary copper ores and to pretreat precious-metal ores in which the gold and silver are locked in a sulfide-mineral matrix; and 3 in aerated stirred-tank reactors to pretreat precious
10.5. Copper–Gold Ores. Copper–gold ores are significant contributors to the overall world gold production. Flotation is the principal process for preconcentration of the copper–gold minerals for subsequent smelting treatment.
