The Mining Process – Waihi Gold

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.

Copper mining. Introduction.

The main ores of copper are: chalcopyrite bornite malachite. The ores are extracted by either traditional mining (open pit or underground) or by leaching. The copper is then recovered using physical and chemical techniques. In this electronic resource, we'll look at the ways in which copper is mined and recovered from its ores.

Coal Mining Methods

To provide a steady flow of coal in a room-and-pillar mine, several stages of mining occur simultaneously in different rooms. A final phase of mining termed "retreat mining" may be performed to recover additional coal by extracting pillars and allowing the roof to fall.

Environmental Risks of Mining

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

When the mineral seam becomes exposed, it is drilled, fractured and the mineral recovered for processing. Open-cut mining can be more effective than underground methods, generally recovering 90% of a mineral deposit, and accounts for about 65% of raw coal production in NSW. Open-cut mining is also used for some gold and copper production in NSW.
