Problems solved by technology

The commonly used traditional collector is butyl xanthate. Although butyl xanthate has a strong collection capacity, it has the disadvantages of poor selectivity, long beneficiation process, and large reagent consumption, which leads to high production costs and is difficult to form. Due to economic benefits, some copper mining enterprises were forced to suspend production, especially in the case of low metal copper product prices in recent years, the situation is even more severe

Embodiment 1

[0028] The composite collector described in this example is firstly mixed according to the mass ratio of butyl xanthate: aviation kerosene: transformer oil = 80:1:1, and then adding water with a mass percentage of 95% for ultrasonic emulsification for 2 minutes. made.

[0029] In this example, a copper oxide ore in Yunnan Province has a grade of Cu0.95% and a copper oxidation rate of 31.13%. The raw ore is ground to -0.074mm (200 mesh / inch), and the sieved material accounts for 70% of the raw ore quality, and the sieved material is added to adopt the traditional collector butyl xanthate and the composite collector prepared by the present embodiment respectively. In the flotation operation, the respective preferred dosages of the two collectors, and under the same conditions of other technological conditions (such as the amount of sodium sulfide, etc.) (see Table 1 for details), carried out the comparative test of the closed-circuit flotation process, and the process is shown i...

Embodiment 2

[0036] The composite collector described in this example is pre-mixed according to the mass ratio of butyl xanthate: aviation kerosene: transformer oil = 80:1:1, and then adding water with a mass percentage of 92% for ultrasonic emulsification and solubilization treatment 2 prepared in minutes.

[0037] In this example, the scale of the flotation plant is 2,000 tons / day, the annual production is 300 days, the butyl xanthate is 8,000 yuan / ton, and the composite collector is 8,500 yuan / ton. A copper oxide ore in Yunnan Province has a selected grade of Cu0.85%, a copper oxidation rate of 42.20%, and the raw ore is ground to -0.074mm. The sieved material accounts for 80% of the raw ore quality. The traditional collector butyl xanthate and this example are used respectively. Prepared composite collector, under the same situation (see Table 3 for details) of two kinds of collectors in each flotation operation, and other technical conditions (such as sodium sulfide consumption, etc.)...

Embodiment 3

[0044] The composite collector described in this example is pre-mixed according to the mass ratio of butyl xanthate: aviation kerosene: transformer oil = 80:1:1, and then add water with a mass percentage of 90% for ultrasonic emulsification and solubilization treatment Prepared in 3 minutes.

[0045] In this example, a copper oxide ore in Sichuan Province has a grade of Cu of 1.32% and a copper oxidation rate of 64%. The raw ore is ground to -0.074mm, and the sieved material accounts for 70%-90% of the raw ore quality. The traditional collector butyl xanthate and the composite collector prepared in this embodiment are respectively used in each flotation operation. The respective preferred dosages of the collectors, and under the same conditions of other technological conditions (such as the amount of sodium sulfide, etc.) (see Table 5 for details), a comparative test of the closed-circuit flotation process was carried out, and the results of the comparative tests of the two co...

Abstract

The invention relates to preparation and application of a copper oxide ore flotation composite collecting agent. The composite collecting agent comprises sodium n-butylxanthate, aviation kerosene and transformer oil, and the mass ratio of the sodium n-butylxanthate to the aviation kerosene to the transformer oil is 80:1:1 through mixing. The composite collecting agent further comprises water, and the mass of the water accounts for 90%-95% of the mass of the composite collecting agent. According to the composite collecting agent, the original nature of components can be kept, and an efficient synergistic effect can be generated. The composite collecting agent is used for replacing sodium n-butylxanthate of a traditional collecting agent, the number of times of copper concentration operation can be shortened by one time, and the total quantity of the collecting agent is reduced by 20%-30%; the beneficial effects of shortening the beneficiation process and reducing reagent consumption are achieved; the aims of reducing the production cost and improving economic benefits are achieved; and the copper oxide ore flotation composite collecting agent is suitable for copper oxide ore flotation.

Description

technical field [0001] The present invention relates to a composite collector, specifically a composite collector for copper oxide ore flotation, and also relates to a preparation method thereof and a method for using the composite collector for copper oxide ore flotation, belonging to flotation separation field. Background technique [0002] my country is rich in copper ore resources, which are divided into three categories: copper sulfide ore, mixed copper ore and copper oxide ore, with a total reserve of 96.896 million tons, ranking sixth in the world, of which copper oxide ore reserves account for a large proportion. With the continuous development and utilization of copper ore resources, there are fewer and fewer easy-to-handle copper sulfide ores and mixed copper ores, and a large number of copper oxide ores have become the main object of mineral processing. [0003] At present, the commonly used beneficiation methods for copper oxide ore include flotation, acid leach...
