2018 8 24ensp;0183;ensp;Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free.

Gekko Systems launched the InLine Leach Reactor (ILR) in 1997 as the worlds first commercial intensive leach production unit. Originally designed to treat high volumes of concentrate from the IPJ as a continuous unit, the ILR was converted to batch operation and found wide spread application treating batch centrifugal concentrates in gold

Sulphide Gold Recovery. Pre concentration of coarse 350 500 micron sulphide associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material.The IPJ, a classic pre concentration device, is effective in gangue rejection prior to further processing of valuable gold bearing material..
