This months im mining Spotlight Feature Article, from the pages of the August issue of International Mining, examines exploration sampling. At a time when the number of exploration programs and studies is very high, it is more than ever important to ensure the sampling employed observes best practice, especially when designing process flowsheets.
typology of the mined substance, waste deposit and mining systems and ore processing method, an estimation, on the basis of the different processes employed throughout the production chain in mining operations and their management at each level, of the main types of waste generated over the last five or ten years.
companies lifecycle emissions, with the aim of improving the methodology further. Decarbonisation strategies for mining companies Diversified mining companies extract a wide variety of natural resources from the earths crust, from energy products to ores requiring processing (e.g. iron ore into steel, or bauxite into
It is more expensive and wasteful to extract a metal from a low grade ore, but most high grade ores have already been used. Extraction methods The extraction method used depends upon the metal's ...
