程潮铁精矿降硫试验研究

Experimental Research on Sulphur Reducing Dressing Test of Chengchao Undersized Iron Concentrate

介绍了程潮磁铁矿筛下铁精矿的主要回收铁矿物为磁铁矿,其铁、硫品位分别为TFe65.51%,S 0.51%,硫含量比较高。通过反浮选及原矿和产品的岩矿物相鉴定,对其进行降硫试验研究。结果表明,通过浮选可将筛下产品精矿的硫含量最低降至0.15%。

The main recovered iron minerals of Chengchao undersized iron concentrate was magnetite, of which the grades of iron and sulphur were TFe65.51% and content was relatively high. The sulphur reducing tests were made on SO. 51%, respectively. The sulphur the iron concentrate through reverse flotation and identification of mineral phases of run-of-mine ore and products. The results indicated that the sulphur content in the concentrate was minimally dropped to 0.15% through flotation.
