Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

This is basically a volumetric issue. you have a mill with a defined volume, and as you put new feed in, it displaces the ore already in the mill. First you need the volumetric capacity of the mill, this is the volume of the mill at rest where the ore just reaches the discharge level (often about 1/3 of the internal volume).
An industrial ball mill operating in closedcircuit with hydrocyclones was studied by five sampling surveys. The aim of the present study was to optimise operating parameters ( charge volume, makeup ball size regime, slurry mean residence time, number of hydrocyclones in operation and hydrocyclone''s feed solids content (S f)) with respect to increasing throughout from 225 to 300 tons ...

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
