Experimental Research on Comprehensive Recovery of Ironmaking Dedusting Ash
摘要
Abstract
According to the properties of ironmaking dedusting ash,the combined flowsheet of preimmersing desal ting-Flotation-magnetic separation-gravity separation was adopted to recover iron and carbon. When carbon was flo tated.the acidized water glass was adopted as dispersant. Meanwhile,it could be used to wash the surface of miner als, effectively inhibiting silicon and other non-metal oxides. When the neutral oil and the acidizing fatty alcohol were selected as mixed collector, the selectivity of the collector was improved. Under the certain technological con dition, the separation index with the carbon grade of 65.42 and its recovery of 81.59% and the iron grade of 54. 28% and its recovery of 67.95% were obtained.关键词
