Typically, this concentrate contains a mixture of gold along with other valuable elements found in sulfide minerals such as copper, lead, zinc, etc. The bulk concentrate is most often filtered and sold to a smelter for further refining. In some cases, the flotation concentrates are processed further to produce bullion -

Fine Gold Recovery

Oct 19, 2007· In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to selectively separate …

Method to extract gold from telluride ores and concentrates

May 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.

How I can separate gold from copper?

Crushed PCBs are fed to a thermal treatment system where they become friable and toxins are removed safely. Thereafter, the PCBs are mechanically disintegrated in a mill and coarse copper is removed from the mill discharge as a clean product.

In gold mining, cyanide solution is sprayed over vast heaps of crushed ore that is spread atop giant collection pads. The cyanide dissolves the gold from the ore as the solution trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the stacks until the ore is depleted.
