| description | Provided is a beneficiation method for high carbonate iron ore, and belongs to the technical field of the mineral processing. The method comprises the following steps: firstly, ore grinding processing is carried out on the high carbonate iron ore after the carbonate iron ore is crushed; secondly, weak magnetic separation, first-stage strong magnetic separation and second-stage strong magnetic separation are carried out on hierarchic flooding products to separate tailings, and concentrates are merged to be used as mixed roughs; thirdly, filtration is carried out on the mixed roughs, heating is carried out to eliminate water, heat preservation is carried out on the mixed roughs for three min to sixty min under a reducing atmosphere condition, and air cooling is carried out on the mixed roughs; fourthly, ore pulp is prepared by adding water, and pre-selection is carried out after stirring; fifthly, fine selection is carried out by an electromagnetic fine selecting machine after fine grinding is carried out, and water is eliminated by filtration. According to the method, the strong magnetic separation and the weak magnetic separation are adopted, baking and reducing are carried out, pre-selection, namely, ore grinding and fine selecting, is carried out, and the products with iron grade larger than sixty percent are obtained. The method has the advantages that the product index is stable, the economical efficiency is good, and resources can be efficiently utilized. |
