Grinding Aids - Metallurgist & Mineral Processing Engineer

Marble showed the same general characteristics but, in this case, water vapour, which led to a 60% increase in speed of grinding compared with a dry atmosphere was the most effective additive. For the grinding of quartz, polar and non-polar atmospheres led to about the same increase in the rate of grind.

What is the chemical composition of quartz?

Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.

Effects of mechanical grinding on pozzolanic activity and ...

At 20 min of grinding, the PSD curve of the ground quartz was typically bimodal, although the ground quartz contained a greater number of smaller particles (<6.0 μm) compared with quartz ground for 5 min; furthermore, the PSD showed a narrowing trend, and the median diameter (D 50) fell to 5.80 μm from 11.16 μm. At 40 min of grinding, the ...

Effect of additives on grinding of magnetite ore ...

12%These investigations established that an addition of 200 g of CaO per metric ton of ore was the most effective in grinding quartz preferentially over magnetite at 75% solids concentration by weight. The limited rheological studies conducted suggest that the effect could either be due to dispersion or the structural modification of quartz.
