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 (, 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 ...
The area has a long history of gold production and remains highly prospective and must therefore be regarded as an attractive exploration area as it has never been subjected to modern exploration techniques. Property Geology. Active mining at the Blanket mine takes place over a 3 km strike that includes 8 discrete ore shoots. Fig NN provides a northsouth vertical projection of the various ...
Mill represents ~15% of production: • Capacity: 12,000 t/d; • Primarily used to treat sulfide ore; • Unconventional mill only a small portion of mill feed is treated with cyanide * Majority of gold (~90%) recovered from carboninpulp circuit * Remainder of gold recovered with gravity separation (spirals, tables and gold wheels)
