Metal mining subverts the seven traditional mining technologies

Fourth, mining technology change

7, no waste mining technology

The goal of waste free mining is to minimize the output and discharge of waste, improve the comprehensive utilization rate of resources, and reduce or eliminate the negative impact of mineral resource development.

Therefore, mining activities should follow the view of industrial ecology, connect the mine ecological environment, resource environment and economic environment, obtain the maximum amount of resources and economic benefits with the minimum emission, and make the ecological environment fully protected.

In order to realize waste free mining, it is necessary to adopt a small mining method, reduce the ore dilution rate, minimize the waste output, and control the waste rock yield from the source.

At the same time, it is necessary to improve the technical level of mineral processing, improve the recovery rate of mineral processing, the comprehensive utilization degree and utilization rate of resources as much as possible, and reduce the discharge of tailings; Develop innovative beneficiation technology and equipment to minimize the unusable components in ore resources due to the low level of beneficiation.

Through underground preselection, the selection plant is built in the underground and other methods, so that waste rock and tailings do not go out of the well, used to backfill the goaf, to realize the effective use of mining waste in situ.

Strengthen comprehensive recycling, realize the recycling of waste, improve the overall utilization level of waste, and strive to achieve zero discharge and zero storage of mine solid waste.
