Autogenous and Semi Autogenous Mills FLMetallurgy Mineral Processing SRK

Rely on our proven track record of SAG and AG Mill superiority Since the early s we have been designing and manufacturing Semi Autogenous SAG and Autogenous AG Grinding Mills under the Fuller Traylor brand Semi autogenous grinding uses a minimal ball charge in the range of 6 15 while autogenous grinding uses ore onlyMine to mill optimisation continued If drill and blast costs need to be increased to improve the quality of fragmentation these costs are far outweighed by the reduction in mill operating costs typically 7 to 10 times any increase in mine costs At the same time the concentrator must be prepared to take advantage

The process design of gold leaching and carbon in pulp Choosing a SAG Mill to Achieve Design Performance

Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carbon in pulp circuit CIP The reagent and utilities operating costs associated with leaching adsorption elution and SAG mill itself and not on the test work program Stated another way money invested in a large SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rat
