A comparative study on the effects of dry and wet grinding

Water scarcity dictates to limit the use of water in ore processing plants particularly in arid regions. Since wet grinding is the most common method for particle size reduction and mineral liberation, there is a lack of understanding about the effects of dry grinding on downstream separation processes such as flotation.

Introduction to Mineral Processing cpchem

The froth, enriched in copper and molybdenum, is removed from the flotation roughers and scavengers. This enriched material is now called the rougher concentrate or cleaner feed. The combined rougher scavenger concentrate may be 5% Cu and 0.06% Mo (a concentration factor of 3 to 10 times is typical).

In direct flotation, columns have been used mainly for cleaner stages due to their capacity for generating high grade froths with fine material. The most common configuration involves a rougher with mechanical cells and a cleaner with columns, after regrinding the intermediate concentrates. This type of flowsheet aims at minimizing grinding costs.
