Experimental Study on Mineral Processing for a Sulfur-bearing Iron Ore from Mongolia
摘要
Abstract
The iron ore from Mongolia has a sulfur content of 3.93 ％.So a mineral processing test was conducted for reducing the sulfur content in the iron concentrate.It adopted a flowsheet of low-intensity magnetic separation-floatation.The results showed that an iron concentrate with a TFe grade of 66.52％,sulfur content of 3.44％ was achieved with the grinding size being-0.074mm 55％.In the desulfurization tests,the iron concentrate is regrounded with the grinding size being-0.074mm 65％.Using sulfuric acid and copper sulfate as regulators and butyl xanthate as collector,and using a reverse flotation flowsheet of one roughing and four cleanings,an iron concentrate of sulfur content at 0.35％ was could obtained.关键词
