Atalaya Mining has commenced the execution of a feasibility study to evaluate the economic viability of producing cathodes from complex sulphide ores prevalent in the Iberian Pyrite Belt through the application of a new extraction process called the E …
With the evolving landscape of gold mineral resource development and utilization, the easily treatable gold resources are continuously decreasing, while refractory gold minerals are becoming the most important resources in the field of gold extraction. In these original ores, most of the gold is encapsulated in the lattice of pyrite and …
Mineral extraction (mining) and petroleum and gas production are major resource extraction activities that provide the raw materials to support our economic infrastructure. An enormous amount of pollution is generated from the extraction and use of natural resources. The Environmental Protection Agency's Toxic Releases Inventory report lists …
Iron ore mining is relatively simple compared to other minerals and metals that require underground tunnels and complex chemical-drive processes, like gold. Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang.
Depending on the location and scale, mining methods may include open-pit mining or underground mining. Open-pit mining involves removing the overburden and extracting pyrite from the exposed ore …
Cobalt Blue (ASX:COB) has announced that ore extraction is underway at its Pyrite Hill deposit to feed its demonstration plant located within the Broken Hill project in New South Wales, with further commissioning to follow. The company reports that decline development has been completed with the first 1,000 tonnes of ore being delivered to …

The findings reveal unexpectedly high concentrations of lithium in pyrite minerals within shale. This discovery could lead to sustainable mining practices that do not require new mines, emphasizing the potential for lithium-sulfur batteries and promoting environmentally friendly resource extraction.
Some sulfides (pyrite, chalcopyrite, galena and antimonite) are also enriched with silver particles. The silver content of galena is as high as 0.1%, sometimes 0.5-1%. The grinding process can not dissociate such fine silver particles. 2. Extraction Method of Silver in Gold-Silver Ore #1 Gravity Separation Method
