Energy Consumption in Mining Comminution

mineral bearing rock, either chemically or physically. Prior to this the ore must be crushed to a size suitable for grinding. Grinding is then done to produce fine particles which can be processed either chemically or physically. Although this paper concentrates on energy consumed in comminution (particle size reduction: crushing and grinding), the minimization of environmental toxicity or

Mineral dressing (= Orebeneficiation)

• Crushing and grinding are usually carried out in a sequence of operations by which the lump size is reduced step by step. There are 3 stages of crushing and 2 stages of grinding. – i. Primary Crushing (coarse crushing): In primary crushing, ore or run-of-mine ore (up to 1 m in size) is crushed down to

Table 12.1 lists some commonly analyzed radioisotopes, their volatile chemical form, and the boiling point of that species at standard pressure. Note that the boiling point may vary depending upon solution, matrix, etc. Often the moisture content, and thus, the chemical composition of a solid is altered during grinding and crushing (Dean, 1995).

Blasting has an important impact on mining and milling well beyond the necessary ability to dig and load the ore efficiently. There is an increasing body of blasting research indicating significant impacts in crushing and grinding. These include increased production through higher output and fewer delays for bridging and jamming by oversize. In addition, fragmentation better suited to the

Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry
