Magnetizing Roasting and Magnetic Separation of Specularite Ore
摘要
Abstract
The iron content in a Xinjiang specularite was 35%, and the impurities of phosphorus and sulfur were 0.024%and 0.011%respectively.Part of the specularite occurred as fine and mi-cro-fine, and formed fine cryptocrystalline structure with the cryptocrystalline fine carbonate .La-boratory tests of magnetic roasting -low intensity magnetic separation were carried out with the run-of-mine.The sample(-2mm) was mixed with coal powder with a mass ratio of 100:12 and roasted at temperature of 800 ℃for 75 min.The as-roasted product was ground to -0.074 mm 90%, and then separated twice by low intensity magnetic separator at 120 kA/m.A concentrate with iron grade of 65 .95%and recovery of 77 .70%was obtained .关键词
