摘要: 武汉钢铁(集团)公司程潮铁矿生产的铁精矿含硫约0.3%,为使其降至0.1%以下,进行了实验室浮选试验。试验结果表明:采用乙黄药与丁黄药的混合药剂作为捕收剂直接进行浮选,可使程潮铁精矿硫含量降至0.095%,但捕收剂用量需500 g/t;将铁精矿磨至-400目占82%后再浮选,则捕收剂用量可减少为200 g/t,而且铁精矿硫含量进一步下降到0.080%。

Abstract: The iron concentrate of WuSteel Chengchao Iron Mine contained about 0.3% sulfur. To reduce the sulfur content to below 0.1%, laboratory flotation test was made. Flotation using the ethyl xanthate and butyl xanthate collector combination could reduce the sulfur in the iron concentrate to 0.095% but needed a collector dosage of 500 g/t, which could be reduced to 200 g/t when the iron concentrate was ground to 82% -400 mesh. Moreover, the sulfur content in the iron concentrate could be further reduced to 0.080%.
