Tech Tip: How Water Quality Affects Coolant Performance

Factors that affect water quality are water hardness, pH, and the presence of chlorides, sulfates, and lead [2]. Generally speaking, hard water is the amount of calcium and magnesium salts, expressed in milligrams of calcium carbonate (CaCO3) per liter of water (ppm). The ideal hardness levels for glass working coolant are between 80 to 110 ppm. Water with hardness value below 70 ppm is ...

Influence of grinding media and water quality on

The grinding of pyrite ore was performed in a Magotteaux Mill® which allowed better simulation of plant chemical conditions by controlling pH and pulp potential during the grinding. Cupric ions were added as an activator prior to the grinding. This work demonstrated that there is no significant effect of water quality on flotation performance of pyrite. The results also showed that the pyrite ...
