MoreMay 01, 2017· The gold-copper concentrate prior to 50 times silica flour dilution has 3.75% Cu distributed amongst a range of reactive copper minerals, such as chalcocite, cuprite and native copper. The gold-copper oxides ore contains 12.9 ppm Au and 0.04% copper. The gold-copper sulfides ore mainly contains chalcopyrite as a copper mineral and it contains
Morecopper in high percentages in a gold ore has negative effects on the efficiencyand economic viability of any goldprojectdueto (1)highcy-anide consumption in which copper will consume at least 2.3 kg of so-dium cyanide for every kilogramme of copper leached; (2) copper competing with gold in the adsorption/stripping circuit, which can ef-

MoreFor special native copper bearing ore bodies or sections of ore bodies rich in supergen native copper, this mineral can be recovered by a simple gravity circuit. Application. Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide.
Moreprocess is usually able to recover 85 to 95 percent of the copper in the ore. The dried concentrate contains approximately 20 -30 percent copper by mass, 30 per cent iron, 30 per cent sulphur, with the remainder including small amounts of gold, silver, and unwanted elements such as arsenic and mercury.
MoreMay 22, 2018· You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
MoreGold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

MoreGold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. Hydraulic mining was used widely in the Californian gold rush, and involved

MoreGold 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
