Pre

The JKMRC has recently reported a novel ore pre-concentration method using high voltage electrical pulses (Part 1 of this paper) The technique utilises metalliferous grain-induced selective breakage under a controlled pulse energy input and size-based screening to separate the feed ore into body breakage and surface breakage components leading to ore grade splitting

Copper extraction

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper) the remainder of the concentrate is iron and sulfur in the chalcopyrite and unwanted impurities such as silicate gangue minerals or other sulfide minerals typically minor amounts of pyrite sphalerite or galena Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate
