The mining ore, in addition to a small number of rich in useful minerals bonanza, the vast majority of low grade ore containing gangue. The metallurgical industry, these low grade ore due to low content of useful component of the complex mineral composition, for smelting to extract metals, energy consumption, high production costs. In order to more economic development and utilization of low grade ore, and to expand the sources of mineral raw materials. Before the ore in the smelting must first be subjected to sorting or enrichment to abandon most of the dirty stone, so that the content of useful minerals to meet the requirements of smelting.
In the beneficiation process. There are two basic processes, one is crushing, the crusher machine to a variety of mineral particles to dissociate from the ore. Another is the sorting. Differences in dissociation of mineral particles according to their physical and chemical properties is to be selected as the different products. This points to leave the vast majority of useful minerals in nature are in close symbiosis with the gangue, and often has the sewing of micro-particles embedded in the cloth, if you do not first make a variety of minerals or ingredients, even though their nature there is another big The difference can not be sorting. Therefore, the full dissociation of useful minerals and gangue, is a prerequisite of any sorting method, crushing and grinding purpose is to make useful minerals closely linked to raw ore and gangue dissociation.
In the concentrator. Crusher machine and grinding operations, equipment investment, production costs, often the proportion of electricity consumption and consumption of steel: the cost of equipment accounted for 60% of production costs accounted for 40% to 60%; electricity consumption accounted for 50% of a 65 % of steel consumption accounts for about 50% or more. Computing choices and operational management of the crushing and grinding equipment is good or bad, largely determines the economic efficiency of the concentrator.
