The Mining Process – Waihi Gold

The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

amrclearinghouse.org :::AMD Basics - PYRITE REACTIONS:::

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.

The social costs of productivity losses also are real and serious. A 1 ton per man-day change in productivity results in a change of 10,000 men employed in underground mining. This change in personnel exposure underground has important safety implications since exposure is a key element in underground mining safety.

Treating Acid Mine Drainage From Abandoned Mines in

Pyrite, an iron sulfide found in both coal and metal mines, has the potential to produce more acid than any other mineral. It can produce 16 units of acid for each unit of pyrite (Brick 1998). In a natural environment, the process in which rock becomes exposed to weathering and releases minerals is very slow (DeLuca 1997). Mining
