Mineral Extraction an overview ScienceDirect Topics

Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into

Extraction of Resources Geology

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

7 Effects of Mining and Processing of Mineral Resources on

The economies of industrialized countries require the extraction and process­ing of large amounts of minerals to make products. As other economies indus­trialize, their mineral demands increase rapidly. The mineral demands of coun­tries in Asia, such as Malaysia, Thailand and South Korea have grown phenom­enally in the last twenty years.

Mineral Mining and Processing Effluent Guidelines

After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments. Wastewater is generated during mineral processing (e.g., stone cutting, wash water, scrubber water), from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants.

Flotation is unquestionably the most important and widely used process to separate minerals, including metals, industrial minerals (Lefond, 1975), and coal. Almost all separation processes are conducted in

Extractive Metallurgy Introduction to Chemistry

The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining it. The cost of extraction must be weighed against the metal value contained in the rock to determine which ores should be processed and which ores are of too low a grade to be worth mining.
