Abstract

The invention discloses a recovery method of fine-grained ilmenite. The recovery method includes the steps that first-section high-intensity magnetic separation treatment is conducted on fine-grainedtailings, and first-section fine-grained high-intensity magnetic concentrate is obtained; screening and classifying treatment is conducted on the first-section fine-grained high-intensity magnetic concentrate, and screen overflow and screen underflow are obtained; spiral concentration is conducted on the screen overflow, and spiral concentrate is obtained; after ore grinding treatment is conductedon the spiral concentrate, ore grinding products are subjected to second-section high-intensity magnetic separation treatment, and second-section fine-grained high-intensity magnetic concentrate is obtained; and flotation is conducted on the second-section fine-grained high-intensity magnetic concentrate, and titanium concentrate is obtained. By means of the recovery method of the ilmenite, the effect of enrichment operation can be effectively improved, the operation cost of recovery can be reduced, and the industrial environment-friendly and high-efficiency recovery of limburgite type low-grade ilmenite is achieved.

Description

technical field [0001] The invention relates to the field of metal recovery, in particular to a method for recovering fine-grained ilmenite. Background technique [0002] Ilmenite is an oxide of titanium and iron, accounting for more than 85% of the world's titanium sources, and is the main ore for extracting titanium. How to reduce the cost of refining and improve the recovery rate of titanium concentrate in the refining process has always been one of the most concerned issues in the industry. [0003] With the increase in demand for titanium products, TiO 2 There is also market space for low-grade ilmenite with a grade of 1.5%-3.0%. However, in the industrial recovery of this type of ilmenite, due to the poor enrichment effect of the strong magnetic operation, the problem of the high cost of the reagents required for the flotation operation is caused, and the final recovery rate of the ilmenite is also not high. not tall. Contents of the invention [0004] The purpos...
