Problems solved by technology

Efficient selection of increasingly lean and refined ferro-titanium ore is the main problem in beneficiation, but the existing collectors mainly use oleic acid and fatty acids as the main raw materials, such as MOS collectors, whose main component is oleic acid, and also contains Toxic arsenic component, easy to cause environmental pollution, high cost and equipment corrosion, and the separation selectivity of ferro-titanium ore and its gangue is not ideal

Embodiment 1

[0047] In order to verify the sorting effect in each component mixed mineral when the flotation main collector (collector A) of the present invention is used alone, adopt the ferro-titanium ore, titanolite and olivine concentrate of Panzhihua, Sichuan in Table 1, and adopt figure 1 Flotation is carried out in the flotation process of the single ore shown. Use the collector A (see Table 2) and foaming agent 2# oil in this embodiment as the flotation agent to carry out flotation to the above three different minerals respectively. The parameters of each group of flotation process are the same, the difference is only in the collection Collector A is different, so as to compare the flotation and sorting effects of different collectors A of the present invention.

[0048] The flotation agent in the present embodiment consists of collector A (in formula I, R 1 and R 2 is a variable), 2# oil is composed in the ratio of 0.095mol:0.005mol. Add the above molar ratio of collector A an...

Embodiment 2

[0055] In order to verify the separation effect of the main collector (collector A) and auxiliary collector (collector B) in the mixed minerals of each component when the main collector (collector A) and the auxiliary collector (collector B) are used in combination in the present invention, the iron and titanium in Panzhihua, Sichuan in Table 1 are adopted. ore, titanopyroxene and olivine concentrates, and using figure 1 The process shown is for flotation. The experiment was divided into 4 groups, two of which used the combination of main collector (collector A) and auxiliary collector (collector B) and 2# oil, in which collector B was benzohydroxamic acid or dodecylamine. The other two groups of experiments are: using the main collector (collector A), and oleic acid (assistant collector), 2# oil combined medication; using the main collector (collector A) and styrene phosphoric acid ( collector), 2# oil in combination.

[0056] Then each flotation reagent is used to float t...

Embodiment 3

[0063] In order to verify the sorting effect of the change in the ratio of the main collector (collector A) and auxiliary collector (collector B) in the present invention in the mixed minerals of each component, the table 1 ferro-titanium ore, titanopyroxene and olivine concentrates from Panzhihua, Sichuan, and used figure 1 The process shown is for flotation. The flotation reagents with different proportions of reagents in this example are used to carry out flotation of the above three different minerals respectively. The parameters of the flotation process in each group are the same. The flotation and sorting effects of flotation reagents with different reagent ratios.

[0064] Each flotation reagent in this embodiment: by collector A (in formula I, R 1 is phenyl, R 2 hydrogen), collector B (dodecylamine), and 2# oil in different proportions (0.1mol in total, see Table 4 for specific proportions). Add collector A, collector B and 2# oil in the above molar ratio to 1L dei...

Abstract

The invention provides a flotation collecting agent, a flotation reagent and a flotation method for improving the separation efficiency of ilmenite and gangue of ilmenite.The flotation collecting agent comprises a collecting agent A, the collecting agent A has a formula shown in the specification. In the formula, R1 is C1-C15 alkyl, C4-C15 cycloalkyl, allyl, ethynyl, phenyl, benzyl or benzyloxy; and R2 is hydrogen, C1-C15 alkyl, C4-C15 naphthenic base, propenyl, ethynyl, phenyl or benzyl. The collecting agent A serves as the flotation collecting agent of the ilmenite, benefited from the special synergistic effect of the benzene ring and the phosphate group, the collecting agent A shows good flotation selectivity and recovery rate, and the recovery rate and grade of the ilmenite can be improved.

Description

technical field [0001] The invention belongs to the technical field of mineral flotation, and in particular relates to a flotation collector for improving the separation efficiency of ilmenite and its gangue, a flotation agent and a flotation method. Background technique [0002] Flotation is a method of separating minerals by using the difference between the hydrophobicity and hydrophilicity of the mineral surface. It is the most widely used mineral processing method. Almost all ores can be sorted by flotation. Such as gold, silver, galena, sphalerite, chalcopyrite, chalcocite, molybdenite, pentlandite and other sulfide minerals, malachite, white lead ore, smithsonite, hemimorphite and Separation of oxide minerals such as hematite, cassiterite, wolframite, ferro-titanium, beryl, spodumene, rare earth metal minerals, and uranium ore. Graphite, sulfur, diamond, quartz, mica, feldspar and other non-metallic minerals and silicate minerals, fluorite, apatite, barite and other ...
