galena ore grind

Towards prediction of oxidation during grinding I. Galena flotation

One hundred g galena, combined with 400 cm 3 water, was ground with 4 kg balls in a specialised mill for 30 min so that 90 wt% of the particles present were less than 53 μm in diameter. The specific surface areas of galena particles measured by BET after grinding with mild steel and chromium media are 1.03 and 0.54 m 2 / g, respectively.
