The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm 2 in. and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh.
Hematite - An oxide of iron, and one of that metals most common ore minerals. High grade - Rich ore. As a verb, it refers to selective mining of the best ore in a deposit. High-grader - One who steals rich ore, especially gold, from a mine. Hoist - The machine used for raising and lowering the cage or other conveyance in a shaft.
With a paltry amount of ore stockpiled, a dump laden with debris, or an old mine map showing the lost ore body, the developer spends the last dime of every investor getting ready to treat the mineral-rich rock. The 500,000 mill, designed to treat 500 tons per day, mills nothing, and the dreams of many become a nightmare. Recovery Process

Bioleaching and mineral bio-oxidation are in commercial use today 1 in dumps to scavenge copper from run-of-mine rock 2 in heaps to leach copper from secondary copper ores and to pretreat precious-metal ores in which the gold and silver are locked in a sulfide-mineral matrix and 3 in aerated, stirred-tank reactors to pretreat precious ...
Talc ores also differ according to their mineralogical composition i.e. the type and proportion of associated minerals present. They can be divided into two main types of deposits talc-chlorite and talc-carbonate. Talc-chlorite ore bodies consist mainly of talc sometimes 100 and chlorite, which is hydrated magnesium and aluminium silicate.
Mill Sizing. The ore throughput rate of a mill is largely dependent on the mining production rate. Generally, it closely related to the mining rate of ore only. The goal is to have the mill operating with little to no downtime, without having to stockpile massive quantities of ore for a feed supply.
