In a typical grinding circuit, ore is fed into the mills where abrasion, attrition and impact reduce its size, ABB says. Usually, the grinding circuit contains at least two interconnected mills with material classifiers (eg cyclones) separating the fine material from the coarse (that then goes for regrinding).
metallic copper has been trialled in two major copper mines. The losses in the float circuit are associated with visible, free, metallic copper. The reduction of copper in the grinding circuit recirculating load reduced the coarse, metallic copper load in the float feed. An overall increase in copper recovery on a specific ore

Crushing and Grinding You will note that the Oracle Ridge project has utilized a twostage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all 5 material for the cone mill with a screen in closed circuit. Normally a threestage crushing circuit would have been more conventional, but with the type of ...
1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
