Pentlandite Crushing Milling Circuit From Ethiopia

AMIT 135: Lesson 6 Grinding Circuit – Mining Mill Operator

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG

AN ASSESSMENT OF PENTLANDITE OCCURRENCE IN

pentlandite in the ore occurs as exsolutions in the pyrrhotite and the grain sizes ranges from 8 to 38 m. about 25% of the nickel bearing pentlandite is medium grained and subhedral. This kind of pentlandite occurs along the cracks of pyrrhotite or as inclusions in pyrrhotite. The rest of pentlandite present is disseminated in the gangue matrix
