Problems solved by technology

[0007] At present, there are still few researches on high-efficiency selective collectors for copper-cobalt separation, especially the copper-cobalt separation combined collectors developed for a certain copper-cobalt ore resource are even rarer.

Embodiment 1

[0020] Preferential flotation of copper and cobalt from a copper-cobalt ore in a Baluba ore body abroad.

[0021] The ore composition of the copper-cobalt ore in the Baluba ore body is very complex and there are many types of minerals. The ore is mainly composed of copper, sulfur and iron, followed by cobalt, titanium, and trace amounts of bismuth, silver and other metal elements, of which copper and cobalt are beneficial components. Through the optical microscope identification of ore light, thin slices, and agglomerates, and the scanning electron microscope energy spectrum analysis of metal minerals in the light slices, it was found that the copper minerals in the ore are mainly chalcopyrite, and its content is 3.33%. Followed by bornite, its content is 0.11%, and a small amount of chalcocite, blue chalcocite, copper blue, etc.; cobalt minerals are mainly sulfur copper cobalt ore, its content is 0.08%, followed by a small amount of sulfur cobalt ore The sulfur mineral is py...

Embodiment 2

[0029] Copper-cobalt separation and flotation of copper-cobalt ore in a Baluba ore body abroad.

[0030] The properties of the ore are the same as those in Example 1. A mixed flotation process is applied to the ore to obtain a copper-cobalt mixed concentrate containing 20.2% copper and 1.08% cobalt. Use activated carbon to remove drugs (200g / t), lime (400g / t, pH 12.5) + BP (combined inhibitor 400g / t) to inhibit cobalt minerals, cobalt pyrite and pyrite, and use different collectors respectively Copper and cobalt separation. Process flow and process conditions see figure 2 , the test results are shown in Table 2.

Embodiment 3

[0036] A copper-lead-zinc polymetallic sulfide ore in China is preferentially selected for copper.

[0037] For the test process and process conditions, see image 3 , the test results are shown in Table 3.

Abstract

The invention relates to combined collector for separation of copper-cobalt sulfide ores. The combined collector is characterized by being made with, by weight, 35-45% of isopropyl ethyl thionocarbamate, 35-45% of kerosene, 10-20% of terpenic oil, and 2-8% of No.120 solvent oil. The combined collector is novel efficient selective collector designed for copper-cobalt separation or preferential copper flotation for copper-cobalt sulfide ores; the combined collector has good selectivity against iron pyrite and cobalt pyrite and high collecting capacity against copper ores; copper recovery rate is increased, cobalt content of copper concentrate is greatly lowered, and cobalt recovery rate is also increased.

Description

technical field [0001] The invention relates to an ore dressing reagent, in particular to a combined collector for sorting copper-cobalt sulfide ore, which belongs to the category of flotation reagents in the mineral processing discipline. Background technique [0002] Flotation is commonly used to recover beneficial elements from copper-cobalt sulfide ores, which generally includes two aspects: one is the separation of sulfide minerals (copper sulfide and iron sulfide minerals) from gangue, and sulfur-based collectors are widely used; It is the separation of copper sulfide minerals and iron sulfide minerals. In addition to the inhibitor of iron sulfide minerals, high-selectivity copper collectors are gradually receiving people's attention. [0003] In terms of pharmacy research, collectors for flotation of copper-cobalt sulfide ore are developing in two ways: improving collection capacity and improving selectivity. A collector with good selectivity for iron sulfide mineral...
