Mining industry requires high amounts of energy to extract and process resources, including a variety of concentration and refining processes. Using energy consumption information, different sustainability issues can be addressed, such as the relationship with ore grade over the years, energy variations in electricity or fossil fuel use. A rigorous analysis and understanding of the energy ...


The success of heap leaching technique on oxides and secondary sulfides has opened up doors for many field trials for processing of sulfidic ores such as chalcopyrite for future commercial exploitation. Chalcopyrite is an important primary copper mineral (Hu et al., 2002, Wang, 2005) which accounts to 70% of the total copper reserves today .

Indium (In) has found use in a range of high-tech applications and is regarded as a strategic or critical metal (Schwarz-Schampera and Herzig 2002; Frenzel et al. 2017; Werner et al. 2017).Indium is a dispersed element with its abundance in the Earth's upper continental crust of just 0.056 ppm (Rudnick and Gao 2004).It is considered as a strongly chalcophile element (e.g., Greaney …


The exploitation of coal and metallic mineral resources worldwide invariably results in the production of large quantities of overburden, gangue, and tailings materials containing significant amounts of sulfide minerals. These sulfide minerals, which include sphalerite, chalcopyrite, galena, and other complex sulfides, are often disseminated in ...


Since the identification and characterization of iron and sulfur oxidizing bacteria in the 1940s, a rapid progress is being made in minerals engineering based on biological activities. Microorganisms can play a beneficial role in all facets of minerals processing, from mining to waste disposal and management. Some of the applications, such as biologically assisted leaching of copper sulfide ...

Hazardous Minerals | WA - DNR

The presence of certain naturally occurring elements, such as arsenic, asbestos, mercury, and uranium can make exposure to the rocks that contain them hazardous. The Washington Geological Survey provides maps and geologic information on minerals related to environmental and public health issues. Much of WGS's information on hazardous minerals shows locations of historic mines


However, the exploitation of this ore means a more complex process, which causes serious environmental and economic problems. For this reason, humans must strengthen the research on the utilization of copper and lead resources. The main copper mineral chalcopyrite is …
