Copper Mountains concentrator was commissioned in May 2011. The circuit consists of a 34 x 20 EGL SAG mill, a Raptor 900 pebble crusher and two 24 x 396 ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 #181;m (325100 mesh), thus determining the ball mill work index (Wi B or BWi).
Industrial Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the toe of the mill when the force of gravity exceeds friction and centrifugal forces.
By this summer, a grinding mill that is bigger around than a Boeing 747 will turn chunks of copper ore into gravelsized bits for smelting and refining. The largest ring gear will make it happen
After ball mill grinding copper ore fine material into the next process: grading. Read More. Ore Crushing Chemistry Department Elmhurst College. Then two ball mills grind the ore to about mm with 3inch steel balls. This copper ore slurry is finally pumped to the flotation deck.
The 24 x Ball Mill The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [ feet] long. They are overflow discharge ball mills with inside diameters of 7315 mm [24 feet] and grinding lengths of 11887 mm [39 feet]. Each Ball mill

Copper ore ball mill in India ensures low operating expenses, high throughput rates and metallurgical advantages in the downstream process stages. Because of the short material dwell time in the mill, the machine settings can be quickly altered, making the process easy to control and permitting rapid compensation for fluctuations in the properties of the feed ore.
percent of the original copper ore) suspended in a waterbased slurry that is emplaced in a tailings storage facility (TSF). Water is required for many activities at a minemill site, including ore production and beneficiation, dust and fire suppression, drinking and sanitation, and minesite reclamation. Assessing
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Copper Ore Ball Mill Description of Copper Ore Ball Mill According to the different beneficiation process, the equipment for copper ore dressing are different, in general, jaw crusher, impact crusher, vibrating screen, ball mill, classifier, flotation machine and dryer.
The ore is ground into a fine powder by large rotating mills. South Mill are called SAG (semiautogenous grinding) mills and ball mills. Only then are the copper minerals broken free of the rest of the rock to be separated by flotation. Read More
