Tin tailings gravity separation method

Tin tailings gravity separation method

Tin is an important non-ferrous metal widely used in fields such as electronics, military industry, aerospace, etc. However, the tailings generated during the mining and processing of tin ore resources not only occupy a large amount of land, but also cause environmental pollution. Therefore, the treatment and resource utilization of tin tailings have become a hot topic at present. This article will introduce a tin tailings gravity separation method to provide reference for related industries.

1、 Characteristics of Tin Tailings

Tin tailings refer to the ore that cannot be selected during the tin ore beneficiation process. Due to the complex composition and structure of tin ore, tin tailings often contain various metal elements such as lead, zinc, copper, etc. In addition, the particle size of tin tailings is relatively fine, generally below 0.074mm, making it difficult to treat them through traditional physical and chemical beneficiation methods.

2 II. Principle of Tin Tailings Gravity Separation Method

The tin tailings gravity separation method is a mineral processing method based on the principle of gravity separation. This method separates metal elements such as tin, lead, zinc, copper, etc. from tin tailings through multi-level sorting such as rough selection, selection, and scanning. The specific sorting process is as follows:

1. Coarse separation: Tin tailings are crushed to a certain particle size through a jaw crusher, and then screened through a vibrating screen to separate ores larger than 2mm as coarse separation products.

2. Selection: The coarse selected products are finely ground by a ball mill, and then classified by a spiral classifier to separate fine-grained ores below 0.074mm as selected products.

3. Scanning: The selected products are scanned and selected through a flotation machine, using a copper exciter and xanthate as reagents to separate metal elements such as lead, zinc, and copper to obtain a tin concentrate.

3、 Advantages of Tin Tailings Gravity Separation Method

Compared with traditional physical and chemical beneficiation methods, the tin tailings gravity separation method has the following advantages:

1. Wide application scope: The tin tailings gravity separation method is suitable for the situation where tin tailings contain various metal elements such as lead, zinc, copper, etc., and has strong adaptability.

2. Good beneficiation effect: The tin tailings gravity separation method adopts multi-level separation, which can separate metal elements such as tin, lead, zinc, copper, etc., and has a good beneficiation effect.

3. Environmental protection and energy conservation: The tin tailings gravity separation method adopts the principle of gravity separation, without the use of chemical agents, reducing environmental pollution and energy consumption.

4、 Application prospects of tin tailings gravity separation method

With the rapid development of China's economy and the increasing demand for non-ferrous metals, the treatment and resource utilization of tin tailings have become a hot topic at present. The tin tailings gravity separation method, as a new type of mineral processing method, has broad application prospects. In the future, we can apply the gravity concentration method of tin tailings to the treatment and resource utilization of Xikuangshan Mine tailings, so as to realize the sustainable utilization of tin resources.

In short, the tin tailings gravity separation method is a new type of beneficiation method with wide applicability, good beneficiation effect, and environmental protection and energy conservation. In the future, we should strengthen the research and application of tin tailings gravity separation methods, and make contributions to the sustainable utilization of tin ore resources.
