Problems solved by technology

[0004] The technical problem to be solved in the present invention is that conventional zinc oxide mineral collectors are often used to collect gangue minerals together with zinc oxide minerals in the process of flotation zinc oxide in peaty slate lead-zinc ore, which has poor collection capacity and selectivity. Floating, resulting in low zinc oxide concentrate grade and recovery rate, it is difficult to realize the efficient recycling of zinc oxide minerals, resulting in the loss of zinc metal resources and other problems, to provide a high-efficiency, cheap, good flotation effect, collection capacity and selection Good performance, can reduce the loss of zinc oxide metal resources in the flotation process, a new type of composite collector for recovering zinc oxide from peaty slate lead-zinc oxide ore, preparation method and application with better economic benefits

Embodiment 1

[0023] Embodiment 1: In this embodiment, an oxidized lead-zinc ore containing peaty slate in a lead-zinc mine in Sichuan is used as the application object, and the oxidation rate of lead and zinc in the lead-zinc ore is greater than 35%. The flotation process is completed under laboratory conditions, and tap water is used as the water for flotation in the flotation process.

[0024] This embodiment is a comparative test of the effects of different collectors, and the test process is strictly in accordance with figure 1 The process shown is carried out. Weigh 1000g of the sample, and grind it for 7.5 minutes at a slurry concentration of 62.5% so that the proportion of mineral particles <200 mesh is 65%, carry out flotation experiments, and use the tailings of zinc sulfide minerals as the zinc oxide mineral selection operation to mine. Stir the ore slurry in the XFD 3L flotation tank for 2 minutes, then add regulator, activator, collector and foaming agent in turn, and stir fo...

Abstract

The invention discloses a novel composite collecting agent for recovering zinc oxide from peat slate lead-zinc oxide ore and a preparation method and application thereof. The collecting agent XK-301 is prepared from the following raw materials: 5-40% of a yellow hydrochloride collecting agent, 5-20% of a hydroxamic acid collecting agent and 60-80% of fatty amine. According to the collecting agentXK-301 disclosed by the invention, the mutual synergistic effect among three different types of collecting agent functional groups is utilized, in the flotation process of the peat slate lead-zinc oxide ore, good selectivity and collecting capacity are shown on zinc oxide minerals, the problem that the zinc oxide minerals and gangue minerals are difficult to separate is effectively solved, the flotation recovery rate and grade of the zinc oxide minerals are improved, and loss of zinc oxide metal in tailings is reduced. Compared with the improved mineral separation process and equipment for thepeat slate lead-zinc ore, the peat slate lead-zinc ore can be prepared by compounding conventional flotation reagents, manpower and material resources are saved to a great extent, the used flotationreagents are easy to prepare, and the raw materials are cheap and easy to obtain.

Description

technical field [0001] The invention relates to the technical field of beneficiation of non-ferrous metal minerals, in particular to a collector for recovering zinc oxide from peaty slate lead-zinc oxide ore, a preparation method and application. Background technique [0002] The beneficiation of lead-zinc oxide ore has always been a difficult problem in the field of beneficiation. In recent years, the flotation principle of "selecting lead-zinc sulfide ore first-selecting lead-zinc oxide ore" is often used at home and abroad to process lead-zinc oxide ore. Flotation", "Direct fatty acid flotation", "Chating agent collector flotation", "Flocculation flotation", "Leaching-flotation", etc., combined with the properties of the ore to be treated are also widely used The combined process of gravity separation, magnetic separation, hydrometallurgy, and photoelectric beneficiation has been developed. Commonly used flotation agents for lead-zinc oxide minerals include: 2-hydroxyl-...
