Foam sorting activator and application thereof

Abstract

The invention discloses a foam separation activating agent, which comprises the following components in parts by weight: 0-10 parts of a soluble copper salt, 5-200 parts of an ammonium / amine salt and1-100 parts of a reducing active agent, wherein the soluble copper salt is selected from at least one of copper sulfate, copper nitrate, copper chloride or copper carbonate, the ammonium / amine salt isselected from at least one of ammonia water, ammonium carbonate, ammonium sulfate, ammonium chloride, diamine hydrogen phosphate, ammonium humate or ethylenediamine phosphate, and the reducing activeagent is selected from at least one of ascorbic acid, hydrazine hydrate, hydroxylamine hydrochloride or hydroxylamine sulfate. The foam separation activating agent is high in activating efficiency, stable and firm in activating effect, good in hydrophobicity of activated materials and high in flotation rate, can effectively improve the foam sorting capacity of the to-be-activated materials, and achieves the efficient foam separation and recycling of target components in the materials.

Description

technical field

[0001] The invention belongs to the technical field of foam separation, in particular to a foam separation activator, and in particular to the application of the foam separation activator. Background technique

[0002] Contains Cu 2+ Soluble copper salts are often used as activation regulators in the froth separation process of metal components, such as copper sulfate as flotation of polymetallic sulfide ore or oxide ores. Studies have shown that Cu 2+ The activation of material foam separation is based on its reaction with the material to be treated to form a hydrophobic film, thereby promoting the interaction between the material and the collector, such as the formation of CuS, Cu(OH) 2 , Cu film. Cu 2+ Activated foam sorting, the main performance is as follows:

[0003] 1) Inhibitory film on dissolved mineral surface

[0004] For example, in mixed sulfide ores, sulfur needs to be recovered, because the ferric hydroxide film on the surface of pyrite h...
