Most of the recent developments made in mining technologies prove to be cost-effective and environment-friendly technologies. For example, Solvent-extraction/electro-winning (SXEW) is a hydrometallurgical process that differs from the traditional method of producing copper by milling, smelting, and refining. The development of the SXEW process helps in the low-cost production of copper from waste and raw ore dumps of copper minerals excavated from copper mines. SXEW helps United States and few other copper-producing countries very much. EESTECH provides environmentally sustainable technologies that have direct application in the world’s coal mining and energy industries. EESTECH’s Hybrid Coalmine Gas Technology (HCGT) is a recognized Clean Development Mechanism (CDM) that uses waste coal and ventilated coalmine methane as a fuel source to produce cost effective clean coal energy. Clean coal technology offer solutions in the fight against global warming.

The development of new mining technologies helps to reduce production costs, enhance the quality of mined metals and minerals , enhance the quality of commodities using mined minerals, reduce adverse environmental effects, health and safety impacts. Thus the mining technological developments benefits consumers and producers, as well as nation’s economy, national defense, health and social well being.
