Beneficiation process for wet-type concentration of titanium concentrate from titanium middlings

Abstract

The invention discloses a beneficiation process for wet-type concentration of titanium concentrate from titanium middlings. The beneficiation process comprises the following steps that S1, titanium middlings raw materials are subjected to sulfur roughing and then divided into sulfur concentration primary ores and sulfur scavenged primary ores; S2, the sulfur scavenged primary ores are scavenged and washed and then divided into sulfur scavenged ores I and sulfur scavenged ores II; S3, the sulfur scavenged ores I and the sulfur concentration primary ores are mixed and then subjected to first-time sulfur concentration to obtain sulfur concentration ores I and middling ores I; S4, the sulfur concentrate ores I are subjected to secondary sulfur concentration to obtain a sulfur concentrate finished product and middling ores II; S5, the scavenged ores II are subjected to iron removal to obtain an iron ore concentrate finished product and titanium coarse ores; S6, the titanium coarse ores aresubjected to roughing to obtain titanium coarse ores I and titanium coarse ores II; S7, the titanium coarse ores II are scavenged to obtain titanium scavenged ores I and tailings; and S8, the titaniumscavenged ores I and the titanium coarse ores I are combined to obtain a titanium concentrate finished product. According to the beneficiation process for wet-type concentration of the titanium concentrate from the titanium middlings, the floating sulfur-magnetic separation concentration process technology is employed, and the quality of the titanium concentrate is improved.

Description

technical field [0001] The invention relates to the field of ore beneficiation, in particular to a beneficiation process for titanium medium ore wet-type beneficiation of titanium concentrate. Background technique [0002] The beneficiation process of titanium ore depends on the composition of the material, and generally uses gravity separation, magnetic separation, electric separation, flotation and other beneficiation processes. [0003] The titanium separation system of titanium ore includes strong magnetic-flotation to produce titanium concentrate, strong magnetic-gravity separation, and single gravity separation process to produce titanium medium ore. Since the Qinggangping mine belongs to the Baima mining area of ​​Panzhihua, the titanium content in the vanadium-titanium magnetite in the Panxi area is relatively low, and it is a refractory ilmenite. The recovery rate of titanium concentrate produced by flotation is low and the production cost is high; The production c...

AI Technical Summary

Problems solved by technology

Since the Qinggangping mine belongs to the Baima mining area of ​​Panzhihua, the titanium content in the vanadium-titanium magnetite in the Panxi area is relatively low, and it is a refractory ilmenite. The recovery rate of titanium concentrate produced by flotation is low and the production cost is high; The production cost of titanium medium ore (TiO2 content 38%) is low, but the sulfur content of titanium medium ore (SO2 content 4%) is relatively high. Due to the high sulfur content, the quality of titanium medium ore is not high, and the stockpiling is less than one month Oxidation, yellowing and agglomeration seriously affect the quality and sales price of the product, causing greater economic losses
