With the continuous development of modern industry, the demand for tin ore is also increasing. However, due to the Scarcity of tin ore resources and the complexity of non cassiterite tin ore, the mining and beneficiation of tin ore become more and more difficult. This article will introduce a non cassiterite tin ore beneficiation technology to help mining companies more efficiently mine and beneficiate.

1、 Characteristics of non cassiterite tin ore

Non cassiterite tin ore refers to ore containing tin in other stone minerals other than cassiterite minerals. Due to the complex mineral composition of non cassiterite tin ore, the extraction of tin ore is difficult due to quartz, Wollastonite, Calcite and other minerals. Therefore, the beneficiation technology of non cassiterite tin ore is more complex than that of tin ore containing cassiterite minerals.

2、 The principle of non cassiterite tin ore beneficiation technology

The principle of non cassiterite tin ore beneficiation technology is to separate useful minerals from useless minerals in the ore through physical, chemical, and biological methods during the beneficiation process, thereby improving the grade and recovery rate of tin ore. Among them, physical methods mainly include gravity separation, flotation, and magnetic separation; Chemical methods mainly include cyanide method and redox method, etc; Biological methods mainly include microbial leaching method and biological oxidation method.

3、 Operation steps of non cassiterite tin ore beneficiation technology

1. Pretreatment of ore

Firstly, it is necessary to pre-treat non cassiterite tin ore. The purpose of pre-treatment is to remove impurities and dust from the ore and reduce interference with subsequent beneficiation work. The pre-treatment methods mainly include screening, washing, and roasting.

2. Reselection

Gravity separation is a physical method of separating useful minerals from useless minerals in ores. The principle of gravity separation is to use the density difference of different minerals in the ore to separate the ore into different layers by gravity. The equipment for gravity separation mainly includes gravity concentrators, spiral separators, and centrifuges.

3. Flotation

Flotation is a physical method of separating useful minerals from useless minerals in ores. The principle of flotation is to use the difference in contact angle between minerals and water to float minerals onto the water surface through bubbles, thereby achieving the separation of minerals. The flotation equipment mainly includes flotation machines, stirring tanks, and air flotation machines.

4. Magnetic separation

Magnetic separation is a physical method of separating useful minerals from useless minerals in ores. The principle of magnetic separation is to use the different magnetic properties of minerals in a magnetic field to separate them through magnetic force. The equipment for magnetic separation mainly includes high-strength magnetic separators, wet magnetic separators, and dry magnetic separators.

Cyanidation is a chemical method that separates useful minerals from useless minerals in ores. The principle of cyanide method is to use the affinity of cyanide to metals to separate useful minerals from useless minerals in ores. The equipment for the cyanide process mainly includes cyanide tanks, adsorption towers, and desorption towers.

6. Bioleaching method

Bioleaching is a biological method to separate useful minerals from useless minerals in ores. The principle of Bioleaching method is to use the Bioleaching effect of microorganisms on useful minerals in ores to leach useful minerals. The equipment of Bioleaching method mainly includes bioreactor, filter, concentrator, etc.

Summary

非锡石锡矿选矿技术 Non cassiterite tin ore beneficiation technology is a method of separating useful minerals from useless minerals in ores. Its principles mainly include physical, chemical, and biological methods. In practical applications, it is necessary to choose appropriate beneficiation methods based on the characteristics of the ore to improve the grade and recovery rate of tin ore.
