Meaning and Purpose
Only high grade ore can be transported into furnace directly, but the amount of high grade ore is little, which can not satisfy the need of metallurgy industry. While it is not economy for processing the low grade ore. So it is necessary to processing the mineral ore in order to improve the economic index of smelting technology.
Except for the useful minerals in the ore, it also contains gangue and other impurities. Mineral processing can separate useful ore from impurities, then achieving one or more kind of useful ore.
Final Product
Final product is concentrate and tailings.
Concentrate is useful ore through mineral processing and suitable for smelting processing, the grade should be high. Tailing is a kind of waste product that most of which is gangue with low useful mineral content. In order to kame full use of mineral resource, the tailings grade should be reduced so as to improve the metal recovery rate.
Sometimes in the process of dressing, there is an intermediate product (called middling). In which the quality of useful mineral component and gangue are rich, so middling is an semi-finished product that need to take further processing.
Scale of Dressing Plant
The dressing plant can be divided into flotation mill, gravity mill, magnetic separation plant, contain flotation ,gravity ,air separation plant and combined dressing plant according to the ways of mineral processing and the need of customer.
The dressing plant can be divided into ferrous metal dressing plant, nonferrous metal dressing plant, precious & rare metal and other nonmetal dressing plant in accordance with raw material property. No matter what kind of dressing plant, its scale should be confirmed before planning, then is the factory site, technical process and so on.
