process flow of gold processing mills fp

Jan 13, 2016 As about 40 per cent, of the ore will pass through a 6,400 sieve, there must be much over-stamping, resulting, no doubt, in the pro duction of a great deal of float-gold and slimes. After the mill has been running for a longer or shorter period, according to circumstances, a clean-up takes place. The crushed ore is carried out in large wooden pails to a Chinaman, who washes it, squatting down by the …

Developing a stepwise approach to simulate a hammer mill

1. Introduction. Comminution represents a large portion of the capital and operating cost of a mineral processing plant. Cohen (1983) estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, up to 70% for tough ores, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to the reduction of ...
