Grinding - Mineral Processing

Ball mill. The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Getting intense about grinding - CIM

The original flowsheet involved grinding in two AG mills and a secondary pebble mill, sequential copper flotation and then nickel flotation in order to produce two separate concentrates. However, about 12 per cent of the copper was not recovered during the copper flotation stage because of poor liberation and grade-recovery constraints.
