Preconcentration of copper ores by high voltage pulses

Abstract The JKMRC has recently reported a novel ore preconcentration method using high voltage electrical pulses (Part 1 of this paper). The technique utilises metalliferous graininduced selective breakage under a controlled pulse energy input, and sizebased screening to separate the feed ore into body breakage and surface breakage components, leading to ore grade splitting.

Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.

IsaMill Wikipedia

The IsaMill usually consists of a series of eight disks mounted on a rotating shaft inside a cylindrical shell (see Figure 2). The mill is 70–80% filled with the grinding medium, and is operated under a pressure of 100 to 200 kilopascals. The disks contain slots to allow the ore slurry to pass from the feed end to the discharge end (see Figure 3).
