Tin multi metal mine comprehensive utilization technology has four innovations: (1) Based on independent silver minerals and temperatures with silver copper minerals and silver copper mineral floating differences, complex silver minerals have developed key technologies for asynchronous and efficient recovery of complex silver minerals. The efficient enrichment of minerals; (2) studied the activation mechanism of the inhibited silver flash zinc ore and difficult to select iron-flash zinc ore in low alkaline medium, developed new high-efficiency activators and capping, and achieved two synchronization Efficient recovery of activation and zinc, silver minerals; (3) Based on physics and chemical properties of tin ore ore ore, developed grading group - synergistic and quasi-selection technology, solving the recycling of micron-based hard choosable stone, realization The refined separation and high value use of tin products; (4) based on tail mine solid waste properties, using strong magnetic separation technology to achieve silicon separation, realize silicon sand resource utilization and tail mining reduce emission reduction, eliminate tailings accumulation Bringing safety hazards.
