铜镍硫化矿鼓风炉熔炼时,降低渣含镍(铜、钴),是提高金属回收率的主要途径。我矿从1964年以来,开展了以降低渣含镍提高金属回收率为目的的生产試驗,狠抓技术措施和生产管理,使渣含镍逐步下降。到1965年3月,渣含镍平均己降至0.1228％,最低月份渣含镍为0.076％,赶上了国外的先进水平。 Copper-nickel sulfide ore blast furnace smelting, reducing slag containing nickel (copper, cobalt), is to improve the metal recovery of the main ways. Since 1964, our mine has carried out the production test aimed at reducing the residue nickel content and increasing the metal recovery rate. We pay close attention to the technical measures and production management so as to gradually reduce the slag nickel content. By March 1965, the average content of nickel in the slag dropped to 0.1228%, and the lowest nickel residue in the month amounted to 0.076%, keeping up with the advanced foreign countries.
