在土耳其迪夫里伊铁矿山所生产的磁铁矿石，在选矿厂进行选矿，其综合尾矿倒进恰尔特河。为了回收有用金属（Cu、Ni、Co、Fe3O4）和减少环境污染，已进行实验室和半工业试验。根据试验结果，已设计出尾矿处理流程；并对一个能力为33万t／a的选矿厂进行了初步可行性研究。一个年产40920t磁铁矿精矿（精矿含铁64．2％）、1074．5tCoS－NiS精矿（Ni回收率为29．8％，Co回收率为67．1％）和1747t硫化铜（回收率为71．1％）的选矿厂已完成设计。 Magnetite produced at Turkey’s Devry Iron Mine is beneficiated at a beneficiation plant and its integrated tailings are poured into the Chatill River. In order to recover useful metals (Cu, Ni, Co, Fe3O4) and reduce environmental pollution, laboratory and semi-industrial tests have been conducted. According to the test results, the tailings treatment process has been designed; and a preliminary feasibility study has been carried out on a concentrator with a capacity of 330,000 t / a. An annual output of 40920t magnetite concentrate (64.2% iron concentrate), 1074.5tCoS-NiS concentrate (Ni recovery of 29.8%, Co recovery of 67.1%) and 1747t copper sulfide (Recovery rate of 71.1%) of the concentrator has completed the design.
