The general use of chemical grinding aids involving several different mechanisms for increasing throughput in the wet grinding of ores has been discussed in a number of recent publications. It appears from industrial scale testing that the use of selective dispersants with certain prespecified operating conditions is an approach which can produce two important results first, increased feed
aids. A grinding aid is typically a polar organic liquid, such as amine, glycol, or water, thats added to a ball mill at a low level less than 0.25 percent. This can increase the grinding rate by 20 to 100 percent compared to a system that doesnt use a grinding aid. Many theories have been postulated to explain how grinding aids improve the

Grinding aids include solutions of glycols, esters of glycols, alkanolamines or carboxylates of alkanolamines. Synthex Organics manufactures a broad range of chemicals for the mining and minerals processing industries
Zalta Grinding Aids for Mining Environments Solenis. Zalta grinding aids lead to gains in grinding productivity by reducing cohesion and adhesion in the ore slurry. This decreases the viscosity andor yield stress as the slurry moves through the ball mill, improving grindability by both cascading motion and freefall ballstriking motion.

The presence of a large mining sector in African countries is a strong influence on the severity of a countrys TB epidemic, especially in countries with a high HIV prevalence, and more needs to be done in the mining industry to control TB, a new Oxford Universityled study has found.
In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high for prolonged periods.
Mining has been identified as one of the global megatrends that the chemical industry is focusing on, since a growing world population and increasing wealth can be expected to result in an increasing need for raw materials to produce consumer goods, and to build infrastructure for housing and transportation.
