Embodiment 1

[0012] The compounding method of the combination agent for the activation and collection of this complex copper-lead-zinc sulfide ore: first at room temperature, according to the mass fraction, 2kg of butyl xanthate and 0.5kg of kerosene were stirred and mixed at 1000 rpm for 5min, and finally 1kg of lemon was added. The acid was stirred and mixed at 800 rpm for 10 minutes to prepare a complex copper-lead-zinc sulfide ore activation and collection combination agent.

[0013] Taking a fine-grained complex copper-lead-zinc sulfide ore in Zhaotong, Yunnan as an example, the ore contains pyrrhotite, sphalerite, galena, chalcopyrite, magnetite, pyrite, arsenite, Siderite, etc. Non-metallic minerals include quartz, calcite, dolomite, chlorite, sericite, carbonaceous, argillaceous, zircon, and feldspar. The components are shown in Table 1.

Abstract

The invention relates to a preparation method of an activating and collecting combined agent for complex copper-lead-zinc sulfide ore and belongs to the technical field of ore beneficiation. The preparation method of the activating and collecting combined agent for the complex copper-lead-zinc sulfide ore comprises the steps that firstly, under the indoor temperature condition, 2-3 parts of sodium n-butylxanthate by mass and 0.25-0.5 part of kerosene by mass are stirred and mixed for 5-8 min at the speed of 800-1000 revolutions per minute; and finally, 0.8-1.6 parts of citric acid is added, and stirring and mixing are conducted for 7-12 min at the speed of 600-800 revolutions per minute, so that the activating and collecting combined agent for the complex copper-lead-zinc sulfide ore is prepared. According to the preparation method, the citric acid, the kerosene and the sodium n-butylxanthate are combined for use, and thus selective activating and collecting effects which are better than the activating and collecting effects of a traditional collecting agent and a traditional activating agent can be achieved on site under the normal temperature condition.

Description

technical field [0001] The invention relates to a preparation method of an activation-collecting combination agent for complex copper-lead-zinc sulfide ores, and belongs to the technical field of mineral processing. Background technique [0002] Although many micro-fine mineral processing plants at home and abroad, especially fine-grained polymetallic sulfide mineral processing plants, the collection effect is not very good. Most of the reasons are that the oxidized fine-grained useful minerals are difficult to effectively recover. It is difficult to effectively solve the problem of recovery and separation of such polymetallics only by adding collectors or activators such as copper sulfate. Because of the difference in floatability and oxidation rate of these polymetallic minerals, their collection and sorting effects are different. The use of citric acid and kerosene combined with assisted xanthate for collection can not only activate the oxidized fine-grained sulfide mine...
