The authors range low-grade copper-nickel ore and mining waste represented by overburden dumps, mill tailings and slag in the territory of the Murmansk Region by the criterion of potential ecological hazard. The determinants of mobility of heavy metals formed in oxidation of sulphides are the content of barren minerals (silicate matrix), pH of pore solutions and exposure to atmospheric weathering (acid rains). The criteria of natural copper-nickel ore and mining waste processability are determined.

按生态危害和湿法冶金加工性对低品位铜镍矿和采矿废物进行分类

作者根据潜在生态危害的标准，对摩尔曼斯克地区境内以覆土垃圾场、工厂尾矿和矿渣为代表的低品位铜镍矿石和采矿废料进行了分类。硫化物氧化中形成的重金属迁移率的决定因素是贫瘠矿物（硅酸盐基质）的含量、孔隙溶液的 pH 值和暴露于大气风化（酸雨）。确定了天然铜镍矿和采矿废物可加工性的标准。
