采用还原熔炼方法处理DY10 5 -11富钴结壳得到富锰渣和熔炼合金 ,在还原剂焦粉配比为 9.5 % ,炉渣碱度 0 .2 9,熔分温度 13 60℃的优化条件下 ,Co、Ni等有价金属入合金率接近 10 0 % ,富集倍数达 5以上 ;Mn入渣率达 97.85 % ,渣含Mn3 2 .89% ,实现了Mn与Co、Ni等有价金属间的有效分离及富集 ,为进一步回收创造了较好的条件 The reduction and smelting method was used to treat the cobalt-rich crusts of DY10 5 -11 to obtain the manganese-rich slag and the smelting alloy. Under the optimal conditions of the reductant coke ratio of 9.5%, the basicity of slag 0.229, the melting temperature 1360 ℃ , Co, Ni and other valuable metals into the alloy rate close to 10% enrichment factor of 5 or more; Mn into the slag rate of 97.85%, slag containing Mn2 2 .89%, to achieve the Mn and Co, Ni and other valuable metals Between the effective separation and enrichment, to create better conditions for further recovery
