Polyacrylamide used for improving flotation recovery in the mining industry

Polyacrylamide (PAM) is a high molecular polymer with strong water solubility and water absorption, so it is widely used in mine beneficiation. The use of polyacrylamide can increase the ore recovery rate and improve the beneficiation effect. This article will introduce how to use polyacrylamide to improve the ore recovery rate and its application in the beneficiation process;

Pulp Conditioning

Polyacrylamide can be used for pulp conditioning to improve its fluidity and stability. In the process of mine beneficiation, the particle size of the ore is different, and the solid particle content in the slurry is different, which will lead to a higher viscosity of the slurry, poor fluidity, and even problems such as layering of the slurry. The use of polyacrylamide can improve the fluidity and stability of the pulp, reduce the paste of the pulp, reduce the loss, and increase the recovery rate of the ore.

flotation

Polyacrylamide can be used in the flotation process to improve the stability of the flotation foam and the hydrophobicity of the ore surface. In the flotation process, the use of polyacrylamide can increase the stability of the foam, so that it is not easy to break during the flotation process and improve the beneficiation effect. At the same time, polyacrylamide can also absorb time on the surface of ore, improve its hydrophobicity, and make it difficult for impurities to adhere to the surface of ore, thereby improving the beneficiation effect and ore recovery rate.

Pulp Filtration

Polyacrylamide can be used in mineral filtration to improve the filtration effect. In the process of ore-based filtration, the neck particles in the ore will block the filter and reduce the filtration efficiency. However, the use of polyacrylamide can improve the fluidity and stability of the ore, reduce the viscosity of the ore, and thus reduce the resistance of the filter. Cold, improve filtration efficiency and ore recovery.

Slurry transportation

Polyacrylamide can be used in the conveying process of mineral tight to improve the fluidity and stability of mineral tight. In the mine beneficiation process, the ore needs to be transported to different processing loads for processing, and the solid particles in the mine will increase the viscosity of the mine and deteriorate the fluidity. The use of polyacrylamide can improve the fluidity and stability of the mine, reduce the stickiness of the mine, thereby reducing the loss of ore pulp and increasing the recovery rate of ore.

environmental protection

The use of polyacrylamide can also reduce the pollution of mines to the environment. In the process of mine beneficiation, it is often necessary to use chemicals for ore leaching, flotation and other treatments, and these chemicals will pollute the environment. Polyacrylamide is a non-toxic, harmless and easy-to-decompose polymer material, which can replace some harmful chemicals and reduce the pollution of mines to the environment.

Summary: The use of polyacrylamide can improve the fluidity and stability of ore pulp, improve the stability of flotation foam and the hydrophobicity of ore surface, reduce the viscosity of ore pulp, reduce loss, improve filtration efficiency and ore recovery rate, and at the same time reduce Environmental pollution from mines. Therefore, the wide application of polyacrylamide in the mine beneficiation process can improve the beneficiation effect, reduce costs and achieve sustainable development.
