Practice of Capacity Enlargement and Energy Saving Transformation of an Iron Ore Dressing Plant in Shaanxi
In order to expand the processing capacity of raw ore from 700 thousand t/a to 2 million t/a and increase the output of iron concentrate,a high pressure roller mill and wet pre-concentration test were carried out on a magnetite ore in Shaanxi.Through the comparison of multi-technical schemes,it is concluded that the addition of high-pressure roller mill and pre-concentration process in the concentrator can reduce the amount of grinding by 860 thousand tons per year,reduce the power consumption of per ton raw ore by 11.94%,and reduce the emission of solid waste by 500 thousand tons per year.The concentrator has achieved energy saving and emission reduction,consumption reduction and efficiency increase.The economic and so-cial benefits of the enterprise are remarkable,and the purpose of improving the production capacity of iron concentrate is achieved.
