Abstract:
A large number of surrounding rocks and sandwiched rocks without minerals are produced in the process of ore mining, which are called waste rocks. Waste rocks are solid wastes which are usually stored in storage. With the continuous improvement of mine environmental protection requirements in China, the waste rock storage and its environmental pollution have become an urgent problem. This paper comprehensively introduces the comprehensive utilization status of waste rocks and the harm caused by mine waste rocks to surrounding water, soil and atmosphere. The comprehensive utilization methods of the kind of waste rocks are points out, which mainly includes valuable metal extraction, engineering utilization and building materials manufacturing. It can provide references for the subsequent harmless and resource comprehensive utilization of mine waste rocks.
