Underground Mining Methods And Equipment

Underground Mining Methods And Equipment The primary operations required in underground are rock breakage an d material handling. If the target is sufficiently soft e.g., coal and rock salt, mechanical excavation utilizing continuous miners, shearers, ploughsplows, and so on, can be employed. In contrast, drilling and blasting are usually employed when the ore is too hard for cutting.The primary operations required in underground are rock breakage an d material handling.

Source Geoscience Australia. Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold.

Lecture 5 Sulphide Minerals And Acid Rock Drainage

Lecture 5 Sulphide Minerals And Acid Rock Drainage Acid and metal rich water originating from oxidation of sulphide minerals is called acid rock drainage ARD. ARD is a naturally occurring process that happens in many rocks containing sulphides that are exposed to oxygen. The process is often slow in nature, impacting low surface areas and low concentrations of acid-producing sulphide minerals.Acid and metal rich water originating from oxidation of sulphide minerals is called acid rock drainage ARD. ARD is a naturally occurring process that happens in many rocks containing sulphides that are exposed to oxygen. The process is often slow in nature, impacting low surface areas and low concentrations of acid-producing sulphide minerals.Waste rock is also a mine residue that typically consists of overburden and material displaced to access the ore body. Waste rock may even contain very low grades of ore but at levels which cannot be processed profitably. Waste rock management basically involves its removal and storage, which may be temporary or long-term.
