Autogenous Grinding Mining Fundamentals

Feb 18, 2019 Autogenous grinding is a process of grinding ore in a rotating cylinder using large pieces of the same ore. such as talc, asbestos, and mica, dry semi-autogenous milling is the preferred choice. Grinding is easily enabled in autogenous mills by attrition. Also, autogenous mills have grate discharges, so as to retain the coarse grinding

Autogenous and Semi-Autogenous Mills

Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding 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
