Technologies for Small Scale Primary Gold Mining
- danger of over milling - mills gold to very thin flakes, - stains the gold with iron - not good for batch processing - in non-mining countries, balls difficult to find - high investment costs compared to capacity Ball mill Advantages: - product size can be very fine (e.g. for flotation, < 150µm) - works with very hard material - can be built,Production of Gold - West Virginia University,The Ball Mill, B-101, grinds the 0.25” ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill,,For overflow ball mills, the charge should not exceed 45% of the mill volume .
