During comminution there is a generation of abraded iron surfaces from grinding media and the broken particles can be deposited on gold surface changing gold particles characteristics and its behavior during recovery processes such as flotation and leaching. In this way, gold particles are smeared and its natural properties are affected.
Cobalt is used in the manufacture of cutting and grinding tools, in pigments and paints, coloured glass, medical implants, electroplating, and increasingly in lithium-ion battery production. Weapons-grade tungsten alloys (tungsten, 91–93%; nickel, 3–5%; and cobalt, 2–4%) are used in armour-penetrating munitions.

As a result, the reduction performance of antimony (III) is unaffected by moisture and high grinding/storing temperatures. Several tests performed in our Central R&D facilities have demonstrated how the reducing properties of antimony (III) remain unchanged even after more than one year. 4. MA.P.E./C05 - MAPEI'S REVOLUTIONARY r
1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C.
