肯皮尔赛矿床(西哈萨克斯坦)顿河选矿厂的工作经验表明,重选法(重介质分选、跳汰)完全保证铬铁矿的顺利选别(见表1)。乌拉尔选矿研究设计院于西伯利亚电钢厂进行的研究以及B.H.沙欣的研究证实,该过程的应用可扩大到更细的粒级。按B.H.沙欣的资料,10-4毫米粒级的重悬浮液分选结果较OMTK-4(?)型跳汰机的分选结果更好。特别是整个细粒级矿流在重悬浮液中分选,精矿中三氧化二铬的含量提高4.4％。分选效率系
Work experience at the Don River beneficiation plant in Kamppiyel (West Kazakhstan) shows that the re-election method (HM separation and jigging) fully guarantees the smooth selection of chromite (Table 1). Research conducted by the Ural Mineral Research Institute at the Siberian steel mills and research by B.H. Sahin confirmed that the process can be extended to finer fractions. According to B.H. Sahin, the 10-4 mm fraction of the resuspension results were better than those of the OMTK-4 (?) Jig. In particular, the entire fine-grained ore stream was separated in the resuspension solution, and the content of chromium oxide in the concentrate increased by 4.4%. Sorting efficiency
