The purpose and significance of mineral

The purpose is to remove the mineral ore and gangue contained a large number of harmful elements, so that useful minerals were enriched, or make a variety of useful minerals symbiotic separated from each other by one or several useful minerals in the concentrate product.
In general, the primary ore can not be directly applied as a metal or products, must be carried out to obtain mineral processing applications, such as the native mineral ore grade is generally a result of mineral resources for the full, rational use and development of national economy is of great significance

Ore mined from the ground called the ore, ore generally by the composition of useful minerals and gangue. Relatively low grade ore generally, not directly smelting, need to be processed to remove most of the gangue and the harmful elements, and thus useful to integrate the rich mineral concentrate for further use.

For the processing of ore dressing process is called. For example, generally contains large amounts of tungsten ore gangue, such as quartz, after dressing removal of a large number of quartz veins like stone, so that tungsten was enriched mineral composition, as concentrate products. </ P>
<p> some ore smelting process contains harmful elements such as sulfur and phosphorus in iron ore, and their content can not be too high, or make the iron brittle. In particular, some symbiotic polymetallic ores, which contain the metal components, such as Cu-Pb-Zn-Fe in the smelting often harm each other, and only after a dressing product can be a variety of concentrates for smelting, respectively. </ P>
<p> In addition, mineral smelting technology on the economic effect is also very obvious, for example, copper concentrate grade from 15% to 16%, can smelting recovery rate of 0.1 ~ 0.15%, production increased by 6 to 8% fuel consumption by 6 to 7%; Another example of iron concentrate grade increased by 1%, the blast furnace pig iron production to increase 2.5%, coke rate decreased by 1.5%. </ P>
<p> In summary, the purpose is to remove the mineral ore and gangue contained a large number of harmful elements, so that useful minerals were enriched, or make a variety of useful minerals symbiotic separated from each other by one or several useful mineral concentrate products. Visible, dressing for the development of mining, mineral resources, make full use of great significance.
