Problems solved by technology

Therefore, the above-mentioned strong magnetic flotation process is more complicated, the production cost is higher, and the dosage of chemicals is large, which has a certain impact on environmental protection.
More importantly, flotation requires fine grinding particle size, which is easy to cause over-grinding, which has a certain impact on the recovery of ilmenite, so that the recovery rate is low and the tailings TiO 2 higher grade

Abstract

The invention provides a sorting system and method for ilmenite. The sorting system for the ilmenite comprises an ore grinding device used for conducting ore grinding on raw ore, a screening device, an iron separation device, a sorting device and a titanium strong magnetic separation device, wherein the screening device, the iron separation device, the sorting device and the titanium strong magnetic separation device are sequentially connected with the ore grinding device. The sorting device comprises a roughing device with a feeding port connected with a tailings outlet of the iron separationdevice, a precise separation device with a feeding port connected with the roughing device, a first scavenging device with a feeding port connected with a tailings outlet of the roughing device and atailings outlet of the precise separation device, and a second scavenging device with a feeding port connected with a tailings outlet of the first scavenging device. Compared with the prior art, a one-time roughing, one-time precise separation and two-time scavenging sorting technology is adopted, sorting of ilmenite is completed through cooperation of specific technological steps, and in addition, the recycling rate is high and the grade of tailings TiO2 is low on the basis that the grade of concentrates TiO2 meets the requirement.

Description

technical field [0001] The invention relates to the technical field of mineral processing, and more specifically relates to a sorting system and method for ilmenite. Background technique [0002] Ilmenite is an oxide mineral of iron and titanium, also known as titanium magnetite, and its main component is FeTiO 3 , containing TiO 2 52.66%, is the main mineral for extracting titanium and titanium dioxide. Ilmenite is distributed between magnetite particles or in cracks, and forms large deposits. The chemical composition of ilmenite is related to the formation conditions: ilmenite produced in ultrabasic rocks and basic rocks has a high MgO content and basically does not contain Nb and Ta; ilmenite produced in alkaline rocks, The content of MnO is relatively high, and contains Nb and Ta; ilmenite produced in acidic rocks has high content of FeO and MnO, and relatively high content of Nb and Ta. [0003] At present, the separation of ilmenite generally adopts the method of s...
