【摘要】：会泽铅锌矿为世界罕见的特富铅锌矿产,深部资源开采条件较为复杂,集"水、深、碎、难"于一体,且为复杂难选多金属氧-硫混合矿石。通过采用机械化盘区上向进路充填采矿法为主、机械化盘区下向进路充填采矿法为辅的采矿工艺,有效防止了井下突水水害,成功控制了深井开采地压活动,可靠缓减了深井开采岩爆,提高了采矿作业安全性,实现了资源高效回收;通过采用先硫后氧分段选别主干流程、等可浮-优先浮选原则流程、多碎少磨-阶段磨矿阶段选别工艺流程等多种流程结构并存的综合选矿新工艺,实现了矿石中有用组分的充分回收;构建了以膏体充填和选矿废水处理回用为核心的废弃物处理与资源化利用技术,不仅实现了生产流程废石、尾矿、矿井水、选矿废水及历史遗留尾矿、水淬渣的资源化利用,而且彻底消除了新生高危污染物膏体制备溢流水、选矿废水处理污泥的潜在危害。在生产中取得了采矿回采率98.95%、贫化率6.50%及选矿金属回收率锌95.70%、铅86.35%、银66.01%、锗77.13%,为金属矿山矿产资源综合利用及清洁生产提供了宝贵的经验。
[Abstract]:Huize lead-zinc deposit is a rare lead-zinc deposit in the world. The mining conditions of deep resources are more complex, which gather "water, deep, broken, difficult" in one body. And for the complex refractory polymetallic oxygen-sulfur mixed ore, the mining process is mainly by using mechanized disk area upward approach filling mining method, and mechanized disk area down path filling method is used as the supplementary mining technology. It can effectively prevent the damage of water inrush, control the ground pressure activity of deep well mining successfully, reduce the rock burst of deep well mining reliably, improve the safety of mining operation, and realize the efficient recovery of resources. By adopting the main separation process of sulfur and then oxygen, the floating-priority flotation principle process, the separation process of multi-stage grinding stage with more crushing and less grinding, and so on, the new comprehensive mineral processing technology is developed, such as the coexistence of various process structures and so on. The full recovery of the useful components in the ore has been realized. The technology of waste treatment and utilization based on paste filling and mineral processing wastewater treatment and reuse is constructed. It not only realizes the production process of waste rock, tailings, mine water, mineral processing wastewater and historical tailings. The utilization of water quenched slag completely eliminated the potential harm of overflow water preparation by paste preparation of newborn and high risk pollutants and the treatment of sludge from mineral processing wastewater. A mining recovery rate of 98.95% was obtained in the production. The dilution rate of 6.50% and the recovery rate of zinc 95.70, lead 86.35, silver 66.01 and germanium 77.13%. It provides valuable experience for comprehensive utilization and clean production of mineral resources in metal mines.
