| titleOfInvention | The enrichment method of low-grade phosphate rock based on mineral dissociation and modification |
| abstract | The invention discloses a method for enriching medium and low grade phosphate rock based on mineral dissociation and modification. The method includes: preparing a pulp with medium and low grade phosphate rock as raw material, adjusting the pH of the pulp to 2-6.5, and using a complexing agent and a directing agent to synergistically dissolve the interface between phosphorus-containing minerals and impurity minerals to achieve efficient dissociation of mineral particles; using amine Cationic-like surfactants adsorb silicon-containing minerals, and saponified fatty acid salts are used to adsorb gangue minerals containing calcium, magnesium, aluminum, and iron impurities; anionic flocculants or neutral flocculants are used to selectively adsorb and flocculate phosphorus-containing minerals; Phosphorus-containing minerals and impurity minerals are separated by a cyclone separation method to prepare phosphorus concentrates and tailings. The method realizes the efficient dissociation, separation and enrichment of phosphorus-containing minerals and impurity minerals in a medium and low-grade phosphate rock system through selective dissolution, adsorption, flocculation and cyclone separation, and has the advantages of high separation efficiency, low cost and short process flow. It provides a new way for the efficient enrichment of low- and medium-grade collophosphate ore. |
