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

Embodiment 1
[0059] The beneficiation process of the titanium middle ore wet type beneficiation titanium concentrate of the present embodiment comprises the following steps:
[0060] In S1, the raw materials of titanium medium ore are roughly separated into sulfur-selected primary ore and sulfur-scavenged primary ore;
[0061] After the titanium medium ore is concentrated by the cloud tin type grading box, the concentration of 30-35% enters 1m 3 Stir in the mixing tank, add 10% H2SO4 25.8L / h to the mixing tank to adjust the pH value to 5.5-6; add foaming agent 2# oil 72g / h; add collector xanthate and black medicine mixed agent, concentration 10% Xanthate 18.9L / h, concentration 10% black medicine 6.3L / h; enter 1.1m after stirring 3 The flotation machine (2 sets) is used for separation, the foam concentrate is the primary ore of sulfur concentrate, and the tailings enter the scavenging from the tank to become the primary ore of sulfur scavenging.
[0062] S2 divides the primary ore of sulf...

Abstract
The invention discloses a beneficiation process for wet type concentration of titanium concentrate from titanium middlings. The process comprises the following steps of S1, carrying out sulfur rough separation on a titanium middling raw material, and then dividing the titanium middling raw material into a sulfur concentration primary ore and a sulfur scavenging primary ore; S2, scavenging the sulfur scavenging primary ore and then dividing the sulfur scavenging primary ore into a first sulfur scavenging ore and a second sulfur scavenging ore; S3, mixing the first sulfur scavenging ore and thesulfur concentration primary ore, and performing primary sulfur concentration to obtain a first sulfur concentration ore and a first intermediate concentration ore; S4, carrying out secondary sulfur concentration on the first sulfur concentration ore to obtain a sulfur concentrate finished product and a second intermediate concentration ore; S5, removing iron from the second scavenging ore to obtain an iron concentrate finished product and a titanium coarse ore; S6, carrying out rough separation on the titanium coarse ore to obtain a first titanium coarse ore and a second titanium coarse ore;S7, carrying out scavenging on the second titanium coarse ore to obtain a first titanium scavenging ore and tailings; and S8, combining the first titanium scavenging ore and the first titanium coarseore to obtain a titanium concentrate finished product. According to the beneficiation process for the wet type concentration of the titanium concentrate from the titanium middlings, a floating sulfur-magnetic separation concentration process technology is adopted, 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...
