Dec 24, 2017 Ore grinding is a major cost operation for the mineral processing industry. The U.S. mining industry consumes more than 400,000 st of grinding rods, balls, and mill liners in wet grinding operations at an annual cost of 300 million a significant portion of the milling cost. A section of a commercial ore grinding operation is shown in figure 1.
May 24, 2019 Hematite positive flotation process is a method of using anionic collectors to float iron ore from raw ore. It can achieve discarding tailings under the coarse particles without desliming. Hematite positive flotation process is featured with simple dosage, low processing cost, which is especially suitable for a single hematite.

The critical pH for passivation of steel balls during wet grinding of hematite ore was found to be 10.5. With slurry pH below this critical value, corrosion played a significant role in the total wear of steel and the wear was temperature dependent. Above this critical value, corrosion was prevented and wear of steel, mainly due to abrasion, was independent of grinding temperature.

Jan 01, 1991 During wet grinding of hematite ore in a synthetic mill water containing 2.0 gL S04 and 0.5 g L Cl , the amount of ball wear in a 30 min run was 0.78 mgmm2. 2. Ball wear can be reduced by the use of inhibitor ranging from 11 to 31 for single
Jan 01, 1990 Corrosion is observed to be limited under the conditions..Studies on ball wear 219 CONCLUSIONS The following major conclusions could be drawn on the basis of this work a In the grinding of Kudremukh iron ore, the ball wear was found to increase with time and with decrease in the product particles size with increase in surface area of ground product for all the three types of balls, namely, cast hyper steel, high chrome cast iron and EN-31 under all grinding
Aug 01, 1990 The behaviour of high chrome cast iron balls under different wet grinding conditions was thus different when compared to that of hyper steel balls. The difference in media wear for the three types of balls in the wet grinding of the hematite-magnetite ore, between nitrogen and oxygen flushing condi- tions for a 60-min period is detailed in Table II.
