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 this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation .

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
economic cutoff gold grade for refractory ores is somewhat higher than nonrefractory ores. The mining industry uses a "rule of thumb" of 80% gold recovery to define the transition from a refractory to a nonrefractory gold ore. Ones under 80% are considered refractory. In assessing the economic benefit of the extra processing

Gold processing 101
· Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 6070% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
Mineral Processing Plant Design
Ore characteristics are a critical element in both crusher selection and plant design. Dry ores require greater provisions for dust suppression and collection, including ... At virtually all mines, ore characteristics change over time, and it can be costly to "design in" the optimal flexibility required to handle such changes.

Breakdown of Gold Recovery at Penjom Mine. INTRODUCTION The Penjom Gold Mine is the largest gold mine in Malaysia. The Penjom ore is high grade, with head grades to the plant ranging between 6 g Au/t and 10 g Au/t, but has been benchmarked as one of the world's worst pregrobbing ores.
Mponeng Gold Mine, Gauteng
Ore processing. Ore mined is treated and smelted at Mponeng's gold plant. The ore is initially ground down by means of semiautogenous milling after which a conventional gold leach process incorporating liquid oxygen injection is applied. The gold is then extracted by means of carboninpulp (CIP) technology.
