with solution to dissolve gold from the ore. It produces a pregnant solution containing gold which is collected in a pond. 7.b and 8.b The pregnant solution is then pumped to the ADR plant where it goes through adsorption columns and an elution circuit to produce an
A total of ten apron feeders arranged in two lines of five feeders each reclaim ore from the coarse ore stockpile. Nine feeders report the coarse ore to two semi-autogenous grind SAG mills operating in closed circuit with pebble crushers and one unit the high pressure grind rolls HGPR. Each SAG mill operates with two ball mills.
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.

individual sections the SAG section or ball mill section. As an example Table 1 presents AGSAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi the calculated figures would suggest that the AGSAG mill is very inefficient while the ball mill is significantly more efficient than Bond would predict.
SAG mill product feeds two parallel ball mills of 6.6 m 11.1 m internal diameter length each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 3032 and 78.5 critical speed. The SAG mill trommel undersize is combined with the ball mills discharge and pumped to two parallel packs clusters of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill
Ore is stockpiled 1 at the processing plant and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed and lime is added 2 to raise the pH of the ore.
