Status and Prospect of Room Temperature on the Flotation of Fluorite
摘要
Abstract
Room temperature flotation of refractory fluorite ore is one of the difficult points in mineral processing.Fluorite at room temperature (15 ℃)flotation reagent research comprises the application status of flotation reagents in different types of fluorite ores,a collection agent modified research and development,fluorite new room temperature (15 ℃)collector fluorite flotation collectors,and efficient gangue inhibitor of fluorite.Based on the present situation of the difficulties of fluorite ore and gangue and calcium silicate gangue flotation separation,traditional oleic acid and its modified products have limitations as fluorite flotation collector.In order to achieve better development and utilization of fluorite resources,this paper executive summary of fluorite ore classification and conventional flotation reagent scheme,focusing on the flotation of fluorite new room temperature(15℃)capture agent types and catchability,oleic acid low-temperature flotation reagent change research,fluorite flotation adjustment agent and its mechanism of action,and suitable polar groups of fluorite flotation collectors at room temperature,in the fluorite surface adsorption capacity is better than that of gangue,less affected by temperature,the melting point is low oleic acid,anti hard water,can maintain its solubility and basic properties of dispersion ability at low temperature,etc.Finally it is pointed out that the fluorite ore dressing of the problems and the research direction in the future.关键词
