Corrosion Rates of Grinding Media in Mill Water

100,000 tons of ore per day may spend approximately $25,000 daily to replace media consumed just in ball milling. Similarly, the iron industry consumed approximately 708,000 tons of grinding media to produce pellets in 1978. The Bureau of Mines is investigating the corrosion of grind­

Beneficiation of Iron Ore - Mineral Processing & Metallurgy

Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500 ...
