Kell is a hydrometallurgical treatment option for the recovery of platinum group metals (PGMs), gold, silver, and base metals from flotation concentrates to refined products on site. The process is cyanide-free, while eliminating emissions of sulphur dioxide, arsenic trioxide, and other toxic species often emitted by smelters and roasters.

Silver-bearing, bulk sulfide concentrates from several Peruvian mines were autoclaved in a l9-L (5gal) laboratory autoclave in Lima, Peru. Cyanidation of autoclaved concentrates, following a hot lime jarosite destruction step, extracted more than 98% of the silver and more than 95% of the gold. Autoclave operating parameters, such as time, …

Lead-Zinc-Gold-Silver Flotation: This Colorado mill, treating a complex lead-zinc ore carrying gold and silver values, uses a Mineral Jig and a "Sub-A" Unit Cell in the closed grinding circuit. The jig recovers coarse and fine heavy minerals (as soon as free) which are difficult to float due to size and specific gravity.

The main equipment used are spiral chute, shaking table, jig and so on. The reselection is often combined with the silver ore flotation process. Cyanide leaching methods is mainly used for silver sulfide minerals. In order to increase efficiency, gold and silver concentrates are selected and then cyanided on-site to produce gold and silver.

These concentrates contain silver and it is estimated by CPM that 60 per cent of the silver in the plant feed reports in a silver-sulphur flotation concentrate produced from a hot acid leach residue as indicated on Fig. 1. This concentrate assays about 8000 glt Ag and recovery of the silver in a saleable fonn is attractive to CPM.

Abstract. Gold is considered a store of value and has been a sought-after metal since the dawn of human civilization. It was known to Egyptians as early as 3100 BC. The value of gold was reported to be two-and-one-half times the value of silver in the code of Menes, the founder of the first Egyptian dynasty. A gold mine in Nubia in Nile valley ...
