If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this isTopic 3: Ore processing and metal recovery - SlideShare,2009. 5. 17.· Heap leaching – processing oxidised or sulphide ore:Cyanide solutions react with gold and silver.Cyanide solutions do not react with oxide minerals.Cyanide solutions do react with sulphide minerals.If ore in the leach heap is contains oxide minerals or is oxidised, the process produces:• gold and silverProcesses - Gekko Systems,2021. 7. 11.· Focussing on the gold industry, Gekko replace high-energy whole ore treatment of gold by carbon-in-leach (CIL) methodologies with beneficial low-energy process solutions. Harnessing both gravity separation and floatation, as well as dramatically reducing the initial mass to be processed by pre-concentration, Gekko flowsheets increase the grade for downstream intensive processing.Mineral processing - Concentration | Britannica,Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill.
