    Ore from the mine has an average copper grade of 0.49% and an average gold grade of 0.39g/t. Crushed ore is further reduced in size by Semi-Autogenous Grinding and ball mills. Once milled it is sent through a flotation circuit which produces a concentrate with a grade of 32% copper and 19.9g/t gold. The mill realizes a copper recovery of 89%.Autogenous and Semi-Autogenous Mills Fruitful,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.MEI Blog: Is the Autogenous Mill a Cornish invention?,An AG mill is a tumbling mill that uses the ore itself as grinding media. The ore must contain sufficient competent pieces to act as grinding media and preferably be high specific gravity which, for example, favors AG milling of iron ores and early deployment of AG mills can be attributed primarily to a need in the iron ore industry to
