Using Life Cycle Assessment To Evaluate Some Environmental

Using life cycle assessment to evaluate some environmental

technological developments in gold ore processing such as hpgr, in-place leaching, innovative flotation techniques, pre-concentration using gravity concentration, oxygen injection, biological oxidation and microwave heating have the potential to reduce the environmental footprint of gold production, but any environmental benefits from these technologies will be strongly dependent on the characteristics of the ore



one percent. the gold content of a good grade gold ore may be only a few one-hundredths of a percent. therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called ‘beneficiation.’ milling is one of the most costly parts of
