Mining Industry Profile Department of EnergyIron processing Britannica

The US mining industry consists of the search for extraction beneficiation and processing of naturally occurring solid minerals from the earth These mined minerals include coal metals such as iron copper or zinc and industrial minerals such as potash limestone and other crushed rocks Oil and natural gas extraction NAICS code 211 is not included in this industryIron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Iron Fe is a relatively dense metal with a silvery white appearance and distinctive

Coal GekkoCoal Wikipedia

Gekko specializes in liberation and gravity processing ultimately providing operations with flexible solutions with emphasis on increased returns for all involved stakeholders The concepts founded within minerals processing have been successfully applied to coal for the benefit of the industryCoal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil Mixing in biomass and using CCS would emit slightly less than the oil process but at a high cost
