Ceramic Grinding Kinetics of Fine Magnetite Ores in the Batch Ball Mill
Aiming to reveal the kinetic characteristics of ceramic ball grinding of fine magnetite comprehensively, two types of ceramic balls ground with the same filling rate and total weight as steel balls were researched. The results show that the breakage rate of ceramic ball grinding is only half of that of steel ball grinding with the same media filling rate. With …
Magnetite
As magnetite ore has lower iron content it must be upgraded to make it suitable for steelmaking. Magnetite requires crushing, screening, grinding, magnetic separation, filtering and drying. The final product is a high iron grade magnetite concentrate (+65% Fe), with typically very low impurities. Further processing produces pellets, which can ...
Mining – Karara Mining
The end result is a high iron grade magnetite concentrate (+65% Fe), with typically very low impurities. The additional processing cost for the production of magnetite concentrate can be offset by the premium price which it attracts from steel mills because of the high iron content compared to benchmark DSO hematite products.
