Energy Consumption in Mining Comminution

2.1 Energy Consumption in Open Pit/ Underground Mines There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where

26-06-2012A ball mill at the old White Pine mine. This was one of many attempts to make mining the Nonesuch Shale pay -- a bed of sandstone with extremely fine copper embedded in it. The Nonesuch mine (in the Porcupine Mountains) was the first attempt, with the old White Pine coming again later. It took quite a long time -- until the 1950's! -- for the Copper Range Company to solve the problem (at

Energy Use of Fine Grinding in Mineral Processing

18-12-2013The smallest ball size typically charged into ball mills and tower mills is inch (12.5 mm), although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al .,[ 7 ] a GIS mill charged with 5-mm steel shot, and with other operating conditions similarly optimized, achieved high energy efficiencies when grinding to less than 20 μ m.

The Rosebery crushing circuit consists of a Primary Jaw Crusher and a Secondary Cone Crusher. During Crushing the ore size is reduced from around 650mm to P80 of 20mm. The Grinding Circuit consists of 2 x Primary Ball Mills and 3 x Secondary Ball Mills.

Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
