The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine.ball mill of size 4.6 dia * 16 long. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
The ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium.increasing efficiency of ball mill recycle.

Grinding Cost Analysis. According to the relevant data analysis, grinding mill has an impact on grinding cost and performance, accounted for 30% in overall mineral operating costs, accounted for 50% in whole grinding cost, so the grinding mill has a great influence on manufacturing operating rates, total grinding efficiency and total operation cost.
The mine is a porphyry copper mine. The technological process is SABC. The Proctor hardness of minerals is f = 5-8, and the feed particle size of ball mill is F80 = 15mm. Because the minerals are hard and the feed particle size is large, the design of the ball mill shell liners are the combination of waveform and T-shape, so the design ...
Apr 24, 2020 The ball mill will be a 5.80 m diameter x 9.86 m EGL overflow mill, with a 5,500 kW fixed speed motor. The mill will operate with between 30% to 35% ball charge. Product from the ball mill will discharge over a trommel, with oversize reporting to the rejects bin. Trommel undersize will gravitate back to the cyclone feed hopper to be classified again.
In a typical copper concentration plant, for example, crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen ﬁ lters undersized ore, normally minus inch, to a ball mill discharge sump. The combined mill discharg-.laboratory ball mill for stone
In the ever-increasing quest for reduced mineral processing costs and increased throughput tonnages, there has been a worldwide move towards larger and larger mill sizes. As such, FLSmidth has supplied some of the world’s largest horisontal grinding mills with ball mills up to 28ft in diameter (22MW) and SAG mills up to 40ft in diameter (28 MW).
