Accessing coal seams requires the removal of overlying soil and rock (the overburden). Once mined, coal needs to be separated from mineral matter through processing, generating a second stream of waste made up of the coarse rejects, which are stored in waste piles, and fine tailings stored in tailings dams.
Mineral processing, metal extraction and metal recovery are the crucial steps required for the extraction of critical metals in the context of re-processing solid mining …
The mining and mineral-based industries extract water from groundwater, streams, rivers, and lakes, for mineral processing, dust suppression, and slurry transport.
The economic development of a country is mainly dependent on important industrial activities such as mining. Because of mining operations, huge quantities of solid wastes especially, overburden and rejects, are generated. As these are not valuable to the owners of the mine, they may be inappropriately disposed of into the environment, …
Nano-minerals and amorphous nanoparticles play a vital role in the contexts of human health and environmental sustainability. For instance, aerosols generated by the process of coal beneficiation adversely affect human health as well as the environment. These are called Coal Cleaning Rejects (CCRs).

CDE Mining has announced a new project with Australian company Arrium Mining to process almost 17 million tons of low grade iron ore fines currently stockpiled in waste dumps and convert it into saleable product (Fig. 1). The investment of Arrium Mining involves the provision of two new processing plants in Australia.
The findings of this review serve as a supporting reference for decision makers concerning the related sustainability issues associated with mining, mineral processing, and solid waste management. …

Chemical mineral processing is a process in which the useful components in mineral raw materials are enriched or purified to obtain concentrates or separate products by using the difference of chemical properties between minerals and chemical processing or chemical processing and physical beneficiation combined.
Mining waste may contain potential minerals that can act as essential feedstock for long-term carbon sequestration through a mineral carbonation process. This study attempts to identify the mineralogical …
the environmental aspect, recycling of mining rejects releases fewer amounts of greenhouse gas and process byproducts. In general, these materials are refined form of resource for recovering useful mineral values therein. Therefore, the process byproducts containing various minerals can be conserved as processed resource for future uses.
Miller and Liu (2005) patented a flow sheet for processing laterite ores for the recovery of Ni and Co which included separating the ore into a beneficiated upgraded ore fraction and a coarse, siliceous low grade rejects fraction which is substantially free from fines and clay minerals. The upgraded ore fraction would be processed separately ...
