Openpit mining, also known as opencast or opencut mining and in larger contexts megamining,, is a surface mining technique of extracting rock or minerals from the earth from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially ...
Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals. Most extraction and beneficiation wastes from hardrock mining (the mining of metallic ores and phosphate rock) and 20 specific mineral processing wastes (see side bar) have been excluded from federal hazardous waste regulations under Subtitle C of the RCRA:

During the natural process of weathering, the rocks gradually release the phosphorus as phosphate ions which are soluble in water and the mineralize phosphate compounds breakdown. Phosphates PO43 are formed from this element. Phosphates exist in three forms: orthophosphate, metaphosphate (or polyphosphate) and organically bound phosphate each ...
The following outline is provided as an overview of and topical guide to mining: . Mining – extraction of valuable minerals or other geological materials from the earth, usually (but not always) from an ore body, vein or (coal) seam. Any material that cannot be grown from agricultural processes, or created artificially in a laboratory or factory, is usually mined.
Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are and, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.
Mining iron ore is a highvolume lowmargin business as the value of iron is significantly lower than base metals it is highly capital intensive and requires significant investment in infrastructure such as rail in order to transport the ore from the mine t,Reasons For Mining Iron Gold And Phosphate In India 26.

Almost all phosphorus is mined as phosphate rock (PO4). Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, loed in southeast Idaho.
An iron mine in Yuhezhai, Yunnan, China, and a copper mine in Bahuerachi, Mexico, are going to be constructed, and the plan is to dispose of produced tailings in tailing reservoirs. Engineering design for the two tailing dams is necessary before the mines can be exploited.
