Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

The broken ore falls to the bottom of the stope, and is extracted at the drawpoints by diesel-powered LHD wheel loaders with a 6.1 cu m bucket capacity. Then the ore is either tipped directly into the passes to feed the crusher or, if the stope is a long way from the crusher, into articulated haulage trucks.

The mixed ore and sulphide ore are milled together by a second sulphide circuit (S2) following the phase 2 expansion. The third phase of expansion includes construction of a new 16mtpa sulphide concentrator through a single stage Semi-Autogenous Grinding (SAG) mill, which can be extended up to 25mtpa by adding a ball mill in the future.

Oct 20, 2014With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of surface depth per hour in a cyanide leach. For large gold particles and

The unwanted waste rock (gangue) falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate.
