Direct and indirect greenhouse gas emissions from mining for green technologies need to be accurately and transparently accounted for, as highlighted by a case study of Chilean copper mining.
These elements play key roles in electronics and renewable energy, but the factors that contribute to their accumulation as accessory minerals in ore deposits are poorly understood. Moreover, the recovery of these byproduct commodities at mining, ore-processing, smelting, and refining facilities can be highly inefficient (reaching less than 5 …

This requires the creation of a co-mining plan customized to produce the coal, rare earth elements, and any other valuable by-products present (cobalt and platinum group metals, for example).
Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States. There is a broad range of TENORM concentrations in copper mining wastes.
Green Mining develops Urban Mining Solutions. Cities generate tonnes of waste daily, all of which contain large amounts of metals as electronic gadgets, for instance, utilize small quantities of precious metals such as gold, silver, palladium, and platinum. Urban mining solutions retrieve these metals and channel them back into the ...
Other than the methods used for extracting gold, there are two other precious metal sourcing methods used for silver: by-product mining and ore processing. By-product …
