Background
With the development of society, titanium metal gradually plays an important role in a series of high-end technical fields such as aerospace, marine ships and the like, and becomes a strategic resource for supporting the development of important fields. Most of the titanium elements in nature exist in the form of ilmenite (iron titanate, feO.2TiO 2 compound). Ilmenite is a major mineral species with industrial and economic value. China is a country with very abundant ilmenite reserves, the reserves reach the second world, but most ilmenite has the characteristic of lean and fine impurities, in order to effectively realize the flotation separation of various minerals, the wettability of the surfaces of the minerals must be artificially controlled through a flotation reagent, the floatable difference among the minerals is enlarged, the effective separation of titanium concentrate and gangue minerals is realized, and the high-efficiency separation of lean and fine impurities ilmenite is realized. The conventional flotation collector has low sorting efficiency. Therefore, the research on the flotation collector with high efficiency and good cost performance of ilmenite is particularly important.

In order to achieve the above purpose, the following technical scheme is adopted:
the preparation method of the ilmenite collecting agent based on the modified plant asphalt comprises the following steps:
Carrying out hydroxylation reaction on plant asphalt and liquid alkali in a high-pressure reaction kettle for 1-2 h;
Cooling to 80-100deg.C, adding complexing agent and surfactant, stirring, and mixing to obtain collecting agent.
According to the scheme, the raw materials are as follows in percentage by mass:
52-58% of plant asphalt, 25% of liquid alkali, 2-8% of complexing agent and 12-18% of surfactant.
According to the scheme, the plant asphalt is plant cotton oil asphalt.
According to the scheme, the liquid alkali is industrial liquid alkali with concentration of 32wt% or 45wt% potassium hydroxide solution.
According to the scheme, the complexing agent is benzyl arsinic acid or benzyl hydroxamic acid.
According to the scheme, the surfactant is at least one of sodium dodecyl benzene sulfonate, sodium fatty alcohol polyoxyethylene ether sulfate and coco diethanolamide.
Compared with the conventional ilmenite collecting agent, the invention has the following beneficial effects:

The hydroxyl and ilmenite ions have certain chelation effect, and chelating adsorption occurs on the surface of minerals, so that the ilmenite has better selectivity. The surfactant molecules adsorb to the mine surface in the mine liquor, changing the surface tension of the liquor. The collector can effectively improve the enrichment of titanium ore, increase the selectivity, and has low price and easy preparation.
