  • Flexible Milling And Grinding Solutions That Last Flsmidth

    It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. autogenous grinding mills involve no grinding media as the ore itself acts as the grinding media. our ball mills are the most robust design in the industry, available with either geared or gearless drive arrangements.semi-autogenous grinding uses a minimal ball charge in the range of while autogenous grinding uses ore only. sag and AG mills operate by lifting oregrinding media and dropping it on the operating bed of the mill charge. high impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in each mill is tailor-made according to the requirements nelson machinery worldwide sales of used mining used mining mineral process equipment minerals grinding, there are ball mill, ultrafine mill As a powdering or pulverizing process, there are both wet grinding and dry grinding; both open circuit grinding and closed circuit grinding.the largest gold mine in the united states is the homestake mine at lead, south dakota. this mine, which is 8,000 feet deep, has accounted for almost percent of total united states gold production since it opened in 1876.
