Tungsten iron ore is an important rare metal ore, mainly used for manufacturing materials such as high-speed steel, alloy steel, tungsten steel, and wear-resistant steel. The process of selecting wolframite is the process of extracting tungsten from wolframite. This article will provide a detailed introduction to the process of selecting wolframite and its operating steps.
Overview of the process flow for selecting tungsten iron ore
The technological process of tungsten iron ore dressing mainly includes ore crushing, ore grinding, ore flotation, tungsten concentrate concentration, tungsten concentrate oxidation, Sodium tungstate reduction, tungsten powder preparation and other steps. Among them, flotation is the core step and the most critical link in the process of selecting tungsten iron ore.
2、 Ore crushing
Ore crushing is the first step in the process of selecting tungsten iron ore, with the aim of crushing the tungsten iron ore into suitable particle sizes for grinding. Ore crushing is usually carried out using equipment such as jaw crushers, cone crushers, and impact crushers.
3、 Ore grinding
Ore grinding is the second step in the process of selecting tungsten iron ore, with the aim of further refining the crushed tungsten iron ore to achieve a particle size suitable for flotation. Ore grinding is usually carried out using equipment such as ball mills and rod mills.
4、 Ore flotation
ore flotation is the core step in the process of selecting tungsten iron ore, with the aim of separating tungsten minerals from other impurities in tungsten iron ore. In the flotation process, it is necessary to use flotation agents and foam agents to float tungsten minerals, and then separate them from other impurities by mechanical separation. Ore flotation is usually carried out using mechanical flotation machines.
5、 Tungsten concentrate concentration
Tungsten concentrate concentration is the fourth step in the process of selecting tungsten iron ore, with the aim of further concentrating the tungsten concentrate obtained from flotation and increasing the tungsten content. Tungsten concentrate concentration is usually carried out through methods such as heavy medium separation, magnetic separation, and gravity separation.
6、 Tungsten concentrate oxidation
The oxidation of tungsten concentrate is the fifth step in the technological process of wolframite separation. Its purpose is to oxidize tungsten in tungsten concentrate into Sodium tungstate. Tungsten concentrate oxidation is usually carried out using high-temperature oxidation method.
7、 Sodium tungstate reduction
Reduction of Sodium tungstate is the sixth step in the technological process of wolframite separation, which aims to reduce Sodium tungstate into tungsten powder. The reduction of Sodium tungstate is usually carried out by hydrogen reduction.
8、 Tungsten powder preparation
The preparation of tungsten powder is the final step in the process of selecting tungsten iron ore, with the aim of processing the reduced tungsten powder into the desired shape and size. The preparation of tungsten powder is usually carried out using powder metallurgy technology.
Summary:
The process of selecting tungsten iron ore is a complex project that requires the cooperation of various equipment and technologies. This paper introduces each step in the technological process of tungsten iron ore dressing, including ore crushing, ore grinding, ore flotation, tungsten concentrate concentration, tungsten concentrate oxidation, Sodium tungstate reduction, tungsten powder preparation, etc., hoping to help you understand the technological process of tungsten iron ore dressing.
