A large number of tailings are piled up in traditional metal ore processing plants, which contain a certain amount of unseparated metal minerals and fine monomer ores. Restricted by backward traditional processes, these residual metal resources cannot be recovered, resulting in serious resource waste and long-term environmental hidden dangers. A large number of tailings stacking occupies land resources and brings potential safety hazards such as dam collapse and water pollution.

Tailings re-crushing and secondary beneficiation is an important way to realize zero-waste mining and resource reuse. The residual metal minerals in tailings are finely disseminated and wrapped in gangue, which requires professional fine crushing and dissociation technology to realize secondary recovery. Ordinary crushing equipment cannot achieve ultra-fine crushing and effective dissociation of tailings minerals.

SMP professional tailings re-crushing and recovery system adopts high-precision fine crushing and graded dissociation technology. The optimized ultra-fine crushing equipment fully breaks tailings aggregates, dissociates wrapped residual metal monomers, and cooperates with multi-stage beneficiation equipment to recover iron, copper, manganese and other valuable metals. The processed tailings waste can also be made into recycled aggregate and building materials.

This tailings resource reuse technology turns mining waste into high-value resources, not only improving the comprehensive recovery rate of metal mines, increasing enterprise economic benefits, but also solving the environmental pollution and safety hazards of tailings stacking, realizing the integration of economic benefits and green environmental protection benefits of mines.
