the media was not occurring in the grinding tests and con­ cluded that the iron ore was more abrasive than the sulfide ore, which resulted in higher abrasion of the steel surface and therefore a reduced proportion of the wear caused by corro­ sion. Remark (16) tested inhibitors to reduce galvanic corrosion currents of grinding media and ...

Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth's crust; surface mining is assumed.
