Abstract

The invention provides a zinc oxide ore floatation agent. The zinc oxide ore floatation agent comprises a collecting agent, a foaming agent and an emulsifying agent, wherein the mass ratio of the foaming agent to the collecting agent is 1:6-1:1, and the mass ratio of the emulsifying agent to the collecting agent is 1:6-1:1. A preparation method comprises the steps that (1) the foaming agent is added into the collecting agent, dissolved at the temperature of 25-80 DEG C and stirred evenly, and the mass ratio of the foaming agent to the collecting agent is 1:6-1:1; (2) an appropriate amount of water is added into the mixture evenly mixed in the first step to obtain a solution with the mass concentration being 0.1-10%; and (3) the emulsifying agent is added to the solution obtained in the second step, so that the collecting agent and the foaming agent are fully emulsified in the aqueous solution, and the mass ratio of the emulsifying agent to the collecting agent is 1:6-1:1. The floatation agent has the advantages of being good in floatation effect and water solubility, high in dispersing capacity, low in cost, high in recovery rate and the like.

Description

Technical field [0001] The invention belongs to the technical field of flotation agents, and specifically relates to a zinc oxide ore flotation agent and a preparation method thereof. Background technique [0002] The development of zinc resources in my country is also facing the following two major problems. The first problem is that my country’s self-produced zinc concentrate cannot meet the demand, and a large amount of zinc concentrate needs to be imported every year; the second problem is that most of the proven sulfide ores in my country have been or are being developed and utilized, and the reserve resources are extremely scarce. Therefore, the development of difficult-to-select zinc oxide mineral resources is extremely urgent. [0003] Flotation is an important method for processing zinc oxide ore. Conventional flotation methods are mainly collected by primary amine collectors after sulfidation. However, because zinc oxide ore is generally a lead-zinc symbiosis ore, its m...
