Title:
EFFICIENT FLOTATION REAGENT SUITABLE FOR DIRECT FLOTATION PRODUCTION OF POTASSIUM CHLORIDE
Document Type and Number:
WIPO Patent Application WO/2024/000083
Kind Code:
A1
Abstract:
An efficient flotation reagent suitable for direct flotation production of potassium chloride, which reagent comprises a collecting agent and a foaming agent. The collecting agent is selected from one or more of amine nitrates, amine sulfates, amine acetates and amine formates; and the foaming agent is selected from one or more of alcohol ether substances comprising one hydroxyl group and two ether groups. A new flotation reagent is used to replace a traditional collecting agent octadecylamine and hydrochloric acid, and a foaming agent #2 oil, for direct flotation of potassium chloride, which overcomes the shortcoming of hydrochloric acid being required in an original reagent preparation process, eliminates environmental pollution resulting from the volatilization of #2 oil, improves the reagent collection performance, reduces the dosage of the reagent, improves the single-pass potassium recovery rate in the flotation process, and forms a chlorine-free potassium chloride flotation reagent system.
