Problems solved by technology

Xanthate collectors have relatively strong collection capacity, but poor selectivity. Copper concentrates carry more impurities, which is not conducive to mineral separation, and it is difficult to improve copper grade; Good, but the collection capacity is relatively poor, and the copper recovery rate is difficult to improve
The combined application of xanthates, black medicines, esters, etc., in production, there are many types of medicines, dispensing and dosing are cumbersome, it is difficult to control in practice, and the dosage is unstable, resulting in fluctuations in production indicators, which is not conducive to full play. The effect of the medicine

Embodiment 1

[0028] Embodiment 1: copper smelting reverberatory slag flotation copper:

[0029] The copper sulfide mineral high-efficiency composite collector using reflective slag flotation copper is composed of: isoamyl xanthate ethyl formate 20%, isopropyl ethyl thiocarbamate 65%, pine oil 5% , kerosene 5%, industrial heptane 5%.

[0030] The reverberatory furnace copper slag can be roughly divided into four phases under the microscope, which are metal sulfide phase, magnetite phase, iron silicate phase and glassy phase, of which iron silicate, glassy and magnetite are mostly contained , the metal sulfide content is less, mainly including chalcopyrite, bornite, copper blue, chalcocite, blue chalcocite, sulfur cobalt ore, sulfur copper cobalt ore, pyrrhotite, etc., among which the recyclable elements are copper.

[0031] Metal sulfides are mostly in the form of pellets and drops, and a small amount of them are small and irregular. They are often concentrated in the slag, and the partic...

Embodiment 2

[0038] Example 2: Flotation of copper with converter slag from a certain copper smelting

[0039] Copper sulfide mineral high-efficiency composite collector for flotation copper smelting converter slag is composed of: 30% isoamyl xanthate ethyl formate, 45% isopropyl ethyl thiocarbamate, terpineol oil 10%, kerosene 8%, industrial heptane 7%.

[0040] The copper sulfide minerals in a copper smelting converter slag are mainly chalcocite, followed by a small amount of bornite and copper blue. Chalcocite mostly forms copper sulfide particles alone, and a small amount intersperses bornite in a grid pattern to form aggregates of copper sulfide, and the boundary between bornite and bornite is not clear; Crystals form copper sulfide. Copper sulfide is mainly distributed in the slag in the shape of pellets and drops of varying thickness, and a small amount is in small irregular shape, which is often dispersed in the slag. Spherical natural copper and fine-grained cuprous oxide are o...

Embodiment 3

[0044] Embodiment 3: certain copper-zinc ore sorting

[0045] The copper sulfide mineral high-efficiency composite collector using the copper-zinc ore is composed of: isoamyl xanthate ethyl formate 10%, isopropyl ethyl thiocarbamate 70%, pine oil 5%, Kerosene 10%, industrial heptane 5%.

[0046] The copper-zinc ore belongs to skarn-type copper-zinc sulfide ore. The main metal minerals in the ore are chalcopyrite, sphalerite, pyrite, limonite, followed by copper blue, malachite, etc.; the gangue minerals are mainly quartz, tremolite, olivine, pyroxene and carbonate etc.; precious metal minerals are natural silver, a very small amount of silver-gold mine and gold-silver mine. The raw ore contains 1.45% copper and 2.50% zinc; the oxidation rate of copper is 5.88%, and the oxidation rate of zinc is 6.65%.

[0047] The experimental research adopts the priority sorting process. When the grinding fineness is -0.075mm and accounts for 70%, the copper recovery rate of this collector...

Abstract

The invention relates to an efficient composite collector for copper sulfide minerals and application of the collector. The collector is characterized by comprising ethyl isopropylxanthogenic formate, isopropyl ethyl thiocarbamate, terpenic oil, kerosene and industrial heptane. A preparation method includes: injecting a certain amount of the isopropyl ethyl thiocarbamate into a container at the temperature of 15-30 DEG C, then sequentially adding the ethyl isopropylxanthogenic formate, the erpenic oil, the kerosene and the industrial heptane under the condition of stirring, stirring for 60 minutes to allow the components to be totally dissolved, and finally subjecting the materials to standing to obtain a brownish red transparent liquid product, namely the efficient composite collector for the copper sulfide minerals. Practical application proves that the collector has the advantages of good selectivity, high in copper sulfide mineral collecting capability, simple production process and no other hazardous substances.

Description

technical field [0001] The present invention relates to a kind of flotation agent and its use, especially to a high-efficiency composite collector of complex copper sulfide minerals and its use. The flotation agent with strong collecting ability and good selectivity belongs to the field of ore dressing agents. Background technique [0002] In the process of flotation beneficiation, in order to change the physical and chemical properties of the mineral surface and the properties of the medium, improve or reduce the buoyancy of the minerals, so as to expand the difference in the buoyancy of various minerals in the pulp, and achieve useful minerals and gangue and useful minerals For the purpose of separating each other, it is usually necessary to add flotation reagents. [0003] At present, the commonly used collectors for flotation of copper sulfide minerals include combined reagents and single reagents. The use of combined agents is beneficial to improve the separation effe...
