A comparative study on the effects of dry and wet

01/09/2019  In mineral processing plants, the choice between wet or dry grinding is one of the critical issues, particularly in dry climate countries. In arid areas such as North Western Australia, the Andes and the Sahara Desert, and Africa, the shortage of water dictates the use of dry grinding methods. However, in the industry, wet grinding is the common method for particle size reduction, except in ...

Effect of Grinding Environment on Galena Flotation

The influence of two types of grinding media in wet and dry grinding of galena on the formation of hydrogen peroxide and its flotation response was examined. Galena ground in mild steel grinding media generated more hydrogen peroxide compared to stainless steel media. Thus, lower flotation recovery of galena ground in mild steel could also be attributed due to the presence of higher amounts of ...

Dry Grinding VS Wet Grinding - Mineral Processing

The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...

Recovery of nickel-bearing pentlandite is adversely affected when the pentlandite grains are coated with serpentine slimes. Using CMC depresses the slimes and allows better flotation of pentlandite. However, adding CMC in a typical 1% to 3% solution requires a handling system so large as to negate any metallurgical gains in the circuit; therefore, an economical and effective method of dry CMC ...
