浅谈金川高冰镍传统精炼工艺技改方案和镍产品结构调整

论述了金川有色金属公司现行高冰镍精炼工艺技改的必要性。在综合国内外高冰镍精炼技术的基础上 ,结合金川有色金属公司的实际情况 ,重点阐述了高冰镍硫酸湿法精炼和氯化精炼工艺的优缺点。指出 ,现行高冰镍精炼工艺的改造应吸取氯化精炼和硫酸湿法精炼两种工艺的长处 ,稳妥地向高冰镍全湿法精炼过渡。文中还对该公司镍产品结构调整提出看法

SUPERFICIAL VIEWS ON TECHNICAL TRANSFORMATION OF JINCHUAN HIGH GRADE NICKEL MATTE REFINING TECHNOLOGY AND ADJUSTMENT OF NICKEL PRODUCT STRUCTURE

The necessity for technical transformation of present high grade nickle matte refining technology in Jinchuan Nonferrous Metals Complex is discussed Based on the summarization of high grade nickel matte refining techniques both at home and abroad, and in the light of practical production of the Complex, the advantages and shortcomings of sulfur acid hydrometallurgical refining technology of high grade nickel matte are emphatically set forth It is pointed out that through absorbing the quintessence of both chlorination refining and sulfur acid hydrometallurgical refining processes, present traditional refining technology should be transformed so as to reliably transit to completely hydrometallurgical refining of high grade nickel matte Readjustment of nickel product structure is also discussed
