Experimental Study on Producing Super Iron Concentrate from an Ordinary Iron Concentrate in Shandong Province
摘要
Abstract
An ordinary iron concentrate from Shandong Province contains 65.46% TFe with SiO2 as the main gangue mineral and trace of harmful elements such as sulfur and phosphorus.Iron mainly exists in form of magnetite with a distribution rate of 96.40%.To prepare super iron concentrate from the ordinary iron concentrate,relevant separation technology had been studied systematically.Consequently,beneficiation experiments of preconcentration-stage grinding and stage magnetic separation-reverse flotation were applied.As a result,the super iron concentrate with iron grade of 71.88%,recovery of 63.98%,silica content of 0.30% and acid insoluble content of 0.19% was obtained after treatment.Meanwhile,other impurities contents were controlled under the standard range.Therefore,using the above process,super iron concentrate with ideal separation indexes could be produced from ordinary iron concentrate,which provided significant reference for the separation of similar iron concentrate.关键词
