How Is Gold Extracted From Gold Ore?

In heap-leaching, the ore is placed on open-air pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered. Heap-leaching helps recover gold from ore that would otherwise be too expensive to process. Other . Another process involves

Ore processing – Waihi Gold

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. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry.

02. General Lead Mining History

Lead mining production eventually increased dramatically in the late 1600s with the introduction of improving technologies together with financial investment brought in by mining companies who saw the potential that the industry offered. The industry reached its peak around 1870 after which many mines closed under the threat of falling ore prices due to imported ore. Some mines however, were

Mining Methods: Block Caving

Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs. If there is enough ore, initial capital will be recouped over the life of the deposit. This is why it is common at large
