Embodiment 1

[0062] like figure 1 As shown, put 600g TiO 2 Add water to the raw ore with a grade of 18.92% to prepare a titanium-containing slurry with a concentration of 55%, and mix it with acid flotation agents: 0.12g fenugreek, 0.048g 2# oil, and 12g of 5% dilute sulfuric acid, and the pH is less than 7 Under acidic conditions, acidic impurity removal roughing, acidic impurity removal sweeping 1, and acidic impurity removal sweeping 2 are carried out sequentially, and the foam products of acidic impurity removal roughing, acidic impurity removal sweeping 1, and acidic impurity removal sweeping 2 are used as Impurities are discarded, and the pulp of acidic impurity removal roughing and acidic impurity removal sweeping one enters acidic impurity removal sweeping one, acidic impurity removal sweeping two, acidic impurity removal sweeping two pulp and 0.5g diesel oil, 0.4g containing 15wt Component B of % oxalic acid, 15wt% sulfamic acid and 70wt% sodium fluorosilicate was mixed for 0.5m...

Embodiment 2

[0065] like figure 2 As shown, put 600g TiO 2 The raw ore with a grade of 18.92% is added with water to form a titanium-containing slurry with a concentration of 45%, and mixed with alkaline flotation reagents: 0.12g fenugreek, 0.048g 2# oil, 1g10% sodium hydroxide, the pH is greater than Under the alkaline condition of 7, carry out alkaline impurity removal rough selection, alkaline impurity removal sweeping one, and alkaline impurity removal sweeping two in sequence. The foam product of impurity removal and sweeping second is discarded as impurities, and the ore pulp of alkaline impurity removal roughing and alkaline impurity removal and sweeping first enters alkaline impurity removal and sweeping first, alkaline impurity removal and sweeping second, and alkaline impurity removal After the ore pulp of sweeping second is mixed with acid flotation agent 0.12g butyl xanthate, 0.048g 2# oil, 12g5% sulfuric acid, acidic impurity removal roughing, acidic impurity removal sweepin...

Abstract

The invention relates to a titanium selection agent and a titanium selection method, and belongs to the technical field of titanium selection. The titanium-selected agent comprises a component A and acomponent B which are packaged in independent units, wherein the component A is at least one of oleoyl sodium glycinate, oleoyl sodium sarcosinate, sodium cocoyl glycinate and sodium cocoyl sarcosinate; and the component B is at least one of oxalic acid, sulfamic acid and sodium fluosilicate. The titanium selecting agent does not contain highly toxic arsine, the dosage of the agent is small, health of workers is protected, sewage is easier to treat, and the requirement for equipment is low. The titanium selecting agent is good in titanium selecting effect and small in use amount, the use amount of the titanium selecting agent is reduced by about 30% compared with an existing titanium selecting agent, and the cost is lower.

Description

technical field [0001] The invention relates to a titanium selection agent and a titanium selection method, belonging to the technical field of titanium selection. Background technique [0002] The titanium selection process of the prior art is as image 3 As shown, the titanium-containing raw ore is firstly subjected to acidic impurity removal pretreatment flotation to remove some impurities, and then adds titanium selection reagents under acidic conditions for flotation. Generally, flotation includes roughing, sweeping and beneficiation, and finally Get Titanium Concentrate. The existing pretreatment method of titanium ore is to add xanthate, 2# oil and other agents to the titanium-containing raw material ore under acidic conditions, and remove foam impurities through a process of roughing and sweeping. [0003] There are many kinds of flotation reagents, including arsines, fatty acids, phosphines, hydroxamic acids and so on. However, due to various reasons, the mixture ...
