Ores near the surface can be quarried after removal of the surface layers. The oreOre Mineral - an overview | ScienceDirect Topics,Unlike many industrial minerals that find direct use after mining and limited beneficiation, the ore minerals, in general, must be reduced to metal by complex processing. Modern mining and mineral extraction procedures are tending towards greater use of chemical and bacterial leaching methods for suitable ores, such as in-situ extraction of some uranium deposits, and heap leaching of some gold ores.

The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges are used to break up waste rock, Sometimes, areas must even be blasted in order to loosen rock so workers can more easily separate the oreunderground mineral processing source,Underground processing plant for fluorspar Mineral . The processing plant roughly consists of two independent production lines, which were installed in two parallel underground caverns. In the first process stage, the blasted raw material is removed from the feed bin by means of reciprocating feeders and fed to a NIAGARA scalper (Fig. 3).www.pwc 2012 Americas School of Mines,2015. 6. 3.· quantity of minerals but which must be removed to gain access to the orebody, and tailings which are the result of a mineral separation process in the concentrator or processing plant. The mining rate includes the mining of both waste and ore. Open pit mining is non‐selective – all high and low grade zones of the orebody are mined
