Gold Mine Closure and Decommissioning: 1 - 5 years. After a mine has ceased operations, possibly because the ore body is exhausted or the remaining deposit becomes unprofitable (uneconomic) to mine, work then focuses on its decommissioning, dismantling and rehabilitation of the land in which it was situated.

As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for gold recovery strictly by this method.

Where the ore is high in silver, typically with a recoverable silver content of more than 10 g/t (0.3 oz/ton) of ore, Merrill-Crowe zinc precipitation is used instead of carbon adsorption. In this process the solution is clarified and de-aerated, then contacted with zinc dust to precipitate metallic gold and silver.

Media Attributions; Metal deposits are mined in a variety of different ways depending on their depth, shape, size and grade. Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1).Creating a giant hole in the ground is generally cheaper …
