size reduction in ore processing
Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level.

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the

Size Reduction In Ore Processing Chile In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution size reduction followed by classification separation by particle size either for further grinding or the next step, concentration of the ore.

size reduction, mixing, forming Homogenisation, Conching The aim of homogenisation is to attain a more even particle size or a more homogeneous blend of materials. It is, for example, applied to whole milk to reduce the size of fat globules so that they stay evenly divided in the milk, thereby preventing skimming of the fat. The liquid (whole

Generally speaking, the purpose of ore concentration is to increase the value of an ore by recovering most of its valuable contents in one or more concentrated products. The simplest case may be represented by a low grade copper ore which in its natural state could not be economically shipped or smelted.

Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.
