Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

A Review on Novel Techniques for Chalcopyrite Ore Processing
Mining of Chalcopyrite Chalcopyrite is a common mineral and is found in almost all sulfide deposit and is often disseminated through igneous rock (Haver and Wang, 1971). For lower grade deposit located near the surface, the open pit method is the most practical for the mining of large tonnages of material.

How Iron Pyrite is Formed |
Metamorphic rocks are formed by heat and pressure, and pyrite could be formed as part of this process, or may form as a replacement mineral within the rock. In sedimentary rocks pyrite is usually found as a replacement mineral, when the iron and sulphur that is present in the sediments chemically combine to replace the original chemical ...

:::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.
