本文叙述从二氧化硫浸出锰矿溶液中分离钴、镍、铜的离子浮选方法。从溶液(42.05Mn,3.24Fe,0.0996Co,0.128Ni和0.148Cu克/升)中,以硫化钠、乙基黄原酸盐作为沉淀剂,实现钴,镍、铜的分离。由于硫化铜、钴镍的黄原酸盐具有强烈疏水性,可用离子浮选方法从溶液中除去硫化铜、钴镍黄原酸盐的沉淀物。铜在硫化铜精矿中,钴、镍在钴镍的黄原酸盐精矿中,均有98%得到回收。扩大试验取得了和小型试验相同的指标。该过程包括分两段加入6%NaOH到钴、镍黄原酸盐中,使钴镍获得有效的分离,约60%的乙基黄原酸盐得到回收。
This article describes the ionic liquid flotation method for separating cobalt, nickel and copper from manganese dioxide solution leached by sulfur dioxide. Separation of cobalt, nickel and copper was achieved with sodium sulfide and ethyl xanthate as precipitants from solutions (42.05 Mn, 3.24 Fe, 0.0996 Co, 0.128 Ni and 0.148 Cu / g). Due to the strong hydrophobicity of copper sulphate and cobalt-nickel xanthates, the precipitate of copper sulphide and cobalt-nickel-xanthate can be removed from the solution by means of ionic flotation. Copper In the copper sulfide concentrate, cobalt and nickel are recovered in 98% of the cobalt and nickel xanthate concentrate. Expand the test to obtain the same indicators and small trials. The process includes the addition of 6% NaOH to cobalt and nickel xanthate in two stages so as to effectively separate the cobalt and nickel, and recover about 60% of the ethyl xanthate.
