Embodiment 1

[0019] Embodiment 1, a low-copper and high-molybdenum ore collector is composed of the following raw materials in parts by weight: 20-25 fractional kerosene higher than 220°C; 6-9 heavy wax; 2-3 motor oil; 1 tricyclic aromatic hydrocarbon ~ 2; emulsifier ⅴ fatty acid polyethanol ester 1 ~ 3. The preparation of the fractionated grade kerosene higher than 220°C is the product of petroleum fractionation when the boiling point is higher than 220°C; the preparation of the heavy wax is: kerosene extracted from petroleum with a boiling range of 220-350°C, The kerosene is a mixture of naphthenes, naphthenes and aromatics. The normal alkanes produced by the action of urea and kerosene account for more than 90% of the heavy wax.

Embodiment 2

[0020] Embodiment 2, in the low-copper and high-molybdenum ore collector according to embodiment 1, it is composed of the following raw materials in parts by weight: kerosene of fractionated grade higher than 220°C 20; heavy wax 6; motor oil 2; tricyclic aromatic hydrocarbons 1 ; Emulsifier v fatty acid polyglycol ester 1;

Embodiment 3

[0021] Embodiment 3, in the low-copper and high-molybdenum ore collector according to embodiment 1 or 2, it is composed of the following raw materials in parts by weight: 25% higher than 220°C fractionated grade kerosene; heavy wax 9; motor oil 3; tricyclic Aromatics 2; Emulsifier v Fatty acid polyglycol esters 3.

Abstract

The invention relates to a low-copper high-molybdenum ore collecting agent and a preparation method thereof. The low-copper high-molybdenum ore collecting agent comprises the following components in parts by weight: 20-25 parts of fractionation-grade kerosene higher than 220 DEG C, 6-9 parts of heavy wax, 2-3 parts of 100/100 motor oil, 1-2 parts of tricyclic aromatic hydrocarbon, and 1-3 parts ofv fatty acid polyglycolate serving as an emulsifier. Fractionation-grade kerosene with the temperature higher than 220 DEG C serves as a main body, a single collecting agent is synthesized into a composite collecting agent in an emulsifying mode, and the collecting agent has the advantages of being simple in preparation method, low in synthesis cost and the like. The collecting agent is good in stability, high in viscosity, high in collecting capacity and capable of effectively improving the recovery rate of molybdenum in the low-copper high-molybdenum ore, has a certain amount of macromolecular aromatic hydrocarbon and easily adsorbs coarse-particle ore.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a low-copper and high-molybdenum ore collector and a preparation method thereof. Background technique [0002] At present, the effective method of recovering copper-molybdenum ore is flotation. The essence is that under strong mechanical agitation, oil droplets are adsorbed and unfolded on the mineral surface to form a hydrophobic oil film, and the oil droplets adhere to the surface of the ore particles, making it have a certain hydrophobicity and buoyancy. However, in actual production, because the grinding fineness of low-copper and high-molybdenum ore does not meet the requirements and the ore particles are relatively coarse, conventional collectors cannot recover copper and molybdenum well, especially the recovery rate of molybdenum is low. [0003] In order to effectively recover copper-molybdenum ore and improve the recovery rate of molybdenum, it is necessary t...
