摘要:

综述了7种含钴原料生产电池级硫酸钴的工艺技术。含钴原料不同,生产电池级硫酸钴的工艺技术也有较大差别。根据含钴原料特性将含钴原料细分为7种:含钴氧化矿、含钴硫化矿、副产钴渣、含钴合金废料、废钴催化剂、钴中间品、含钴电池废料。以含钴原料为出发点,对各种含钴原料生产电池级硫酸钴的工艺进行了综述。详细介绍和总结了浸出和精炼工艺的进展,并展望了电池级硫酸钴生产工艺的发展方向。

关键词: 电池级硫酸钴, 含钴原料, 生产工艺

Abstract:

The main technological processes for producing battery grade cobalt sulfate from seven kinds of cobalt-containing raw materials were reviewed.The preparation technologies of cobalt sulfate for battery use varied with different raw materials.According to the characteristics of cobalt containing raw materials,cobalt containing materials were subdivided into seven kinds:cobalt-containing oxide ore,cobalt-containing sulfide ore,cobalt residue of byproduct,cobalt-containing alloyed scrap,cobalt-containing dead catalyst,cobalt-containing intermediately materials,and cobalt-containing waste batteries.In this pa-per,the processes of producing cobalt sulfide by various cobalt materials were reviewed with cobalt containing raw materials as the starting point.The progress in the processes of leaching and refining in production was introduced and summarized in detail,and the development direction of the production process of battery grade cobalt sulfate was also prospected.

Key words: battery grade cobalt sulfate, cobalt-containing raw materials, production technology
