plant andor full-scale plant. In the case of leaching and CIPCIL such data are relatively easy to obtain for existing plants assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant such data are much more difficult to come by particularly if the ore is from a deep underground mine.

The Olympic Dam is a huge mining centre located in South Australia 560km north-west of Adelaide. Home to a major oxide copper gold deposit producing copper uranium gold and silver the site hosts an underground mine and an integrated metallurgical processing plant.
Artisanal and Small-Scale Gold Mining Without Mercury. In many countries elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials forming a mercury-gold amalgam which is then heated vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant .
Gold processing - Gold processing - Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade e.g. 3 to 10 parts per million that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for .
