Abstract

The invention discloses a quartz sand tailings treatment and resource utilization process, and belongs to the technical field of quartz sand tailings production. The quartz sand tailings treatment andresource utilization process solves the problem that existing quartz sand tailings serve as pollutants to be discharged, and cannot be effectively used. The process comprises the following steps of firstly, quartz sand tailings purification; secondly, quartz sand tailings primary grading; thirdly, quartz sand tailings magnetic separation; fourthly, quartz sand tailings water removal; fifthly, quartz sand tailings drying; sixthly, quartz sand tailings secondary grading; seventhly, quartz sand tailings resource utilization. The process is suitable for quartz sand tailings treatment and resourceutilization.

Description

technical field [0001] The invention belongs to the technical field of quartz sand tailings production, and in particular relates to a process for the treatment and resource utilization of quartz sand tailings. Background technique [0002] Quartz sand tailings are valuable mineral resources. According to the statistics of relevant agencies, the annual discharge of quartz sand tailings in my country is about 10 million tons. Discharging such a large amount of quartz sand tailings will cause serious environmental pollution, resulting in the occupation of cultivated land, rivers, Reservoir silting and other adverse consequences. Therefore, resource utilization of quartz sand tailings has become an inevitable trend, and how to resource utilization of quartz sand tailings has become a key research topic for many domestic enterprises. Many domestic enterprises are relatively backward in production technology and dust prevention, especially in the process of dry processing of quar...
