Picking of ore

Extraction metallurgical beneficiation of antimony and antimony ores are closely related, which is mainly manifested in: (1) can be used to provide raw materials for mineral smelting; (2) there is any smelting process include mineral content; (3) with dressing The combination of metallurgical technology can achieve the purpose of comprehensive utilization of mineral raw materials.
The ore dressing method of strontium ore is utilized due to the large number of minerals, hand selection, re-election (including heavy medium dressing), flotation, and separation flotation.
The hand selection of strontium ore is based on the difference in color and gloss shape of strontium-bearing minerals and gangue minerals in strontium ore. By means of the worker's eyesight, the method of hand picking on the belt for conveying ore is a primitive. Beneficiation method, but because the strontium minerals are often produced by coarse crystals or massive aggregates, the hand selection can obtain higher grade massive strontium concentrate, which is suitable for the requirements of bismuth metallurgy technology. Therefore, some major puerperium countries in the world There are still some hand-selected roles. The following table lists the technical conditions and reference indicators for belt hand selection.

Hand-selected block-type antimony concentrate, as long as the antimony concentrate containing more than 10% of antimony can be directly calcined and calcined in a vertical well roasting furnace to prepare antimony trioxide; In the mine, pure strontium trisulfide (commonly known as oyster) can be obtained by melting.
