在酸性氯化物溶液中,用锰结核和含锰氧化矿石氧化浸出镍冰铜。用X射线衍射和扫描电镜研究浸出残渣的矿物学。结果发现,溶解镍冰铜过程很复杂。镍冰铜溶解时,颗粒表面裂开,浸出过程中形成的元素硫作为粘结剂将碎裂物聚集成团。在低酸浓度(0.5mol/LHCl)下,冰铜中的镍可被选择性浸 Nickel matte is oxidized and leached with manganese nodules and manganese-bearing ores in an acid chloride solution. Study on Mineralogy of Leaching Residue by X - ray Diffraction and Scanning Electron Microscopy. The results show that the process of dissolving nickel matte is very complicated. Nickel matte is dissolved, the surface of the particles is cracked, and the elemental sulfur formed during the leaching process aggregates the chippings into clusters. Nickel in matte can be selectively impregnated at low acid concentrations (0.5 mol / LHCl)
