Characteristics of Sulphide Iron Ore

Sulphide iron ore deposits are mainly formed under endogenous action, and the crystals are commonly hexagonal, octahedral and pentagonal dodecahedral. Sometimes it is golden yellow, sometimes brassy, and has a bright yellow metallic luster. Specific gravity 4.95-5.20, hardness 6.0-6.5, streaks of greenish-black, brittle, easily broken by knocking, broken surface is uneven. When burned, it has blue flame and pungent sulphur-yellow odour, and should not be stored in open air or poorly ventilated warehouses.

Uses of Sulphurous Iron Ore

1, the most important use is the production of sulfuric acid and sulfur. Sulphuric acid is the largest consumer of sulphur, and more than 70% of China's sulphur is used in sulphuric acid production. Fertiliser is the largest consumer of sulphuric acid, consumption accounts for more than 70% of the total amount of sulphuric acid, especially phosphate fertiliser consumes the most sulphuric acid and has the largest increase.

2, sulfuric acid in addition to chemical fertilizers, but also for the production of phenol, potassium sulfate and other 90 kinds of chemical products; light industrial system of bicycles, leather industry; textile system of viscose, fibre, vinylon and other products; metallurgical system of steel pickling, fluoride salt production sector; petroleum systems, crude oil processing, petroleum catalysts, additives, as well as the pharmaceutical industry and so on, can not do without sulfuric acid.

3, high-grade sulfuric iron ore slag can be recycled iron, etc.; low-grade slag can be used as cement ingredients, slag can also be recycled a small amount of silver, gold, copper, aluminium, zinc and cobalt.

4, in addition to the above applications, the consumption of sulphur in the industry and the manufacture of matches, cement sleeper treatment, medicine, gunpowder and so on.

Introduction of Sulphide Iron Ore Process

There are two commonly used methods of sulphide iron ore beneficiation, one is re-election method and the other is flotation method. The re-election method has its advantages for the beneficiation of coarse and medium grained sulphurous iron ore, which is more practical, and the flotation method mainly deals with micro-fine grained sulphurous iron ore, and this method can obtain higher beneficiation indexes. In its beneficiation process, generally use jaw crusher, impact crusher, electromagnetic vibrating feeder, rod mill, ball mill, flotation machine and other major equipment, no matter which beneficiation method, the user should be based on their own raw ore situation to choose, so that it is a reasonable investment.
