More Information
Summary:The invention belongs to the technical field of flotation reagent emulsification, and discloses an emulsifier-free coal flotation O/W emulsion type collecting agent and a preparation method and application thereof.The emulsifier-free coal flotation O/W emulsion type collecting agent is composed of 10-50% of collecting reagent, 0.01-2% of polysaccharide additive and the balance water, and the total weight of all the raw materials is 100 parts. When the O/W emulsion type collecting agent is prepared, a subject-object inclusion supramolecular effect is generated between the polysaccharide additive and hydrophobic carbon chains in the collecting agent, a supramolecular structure similar to amphiphilic characteristics of a surfactant is formed, and then the collecting agent is prepared into an O/W emulsion which is uniformly dispersed and small in particle size under the condition of no emulsifier. And meanwhile, a trace amount of alpha-amylase is added in the subsequent flotation process, so that the O/W emulsion
