摘要:
为了较好地实现磷矿反浮选脱硅,选取适宜的胺类捕收剂及合理的浮选条件非常关键. 通过单泡管试验,对比研究椰油二胺、工业二胺、十二胺、86D(脂肪一胺)等4种不同胺类捕收剂对胶磷矿的浮选效果. 纯矿物试验结果表明:不同的胺类捕收剂具有不同的浮选性能,在不同的pH值下同一胺类捕收剂的浮选能力不同;在低用量、弱酸性介质中,十二胺对胶磷矿的捕收能力优于椰油二胺、工业二胺,最低是长碳链的一胺86D;在相同pH值条件下,碳链组成相同的脂肪二胺捕收能力强于脂肪一胺,碳链较长的脂肪一胺比碳链短的脂肪一胺捕收能力弱;在酸性介质中胺类捕收剂对胶磷矿的捕收能力比在碱性介质中弱. 实际矿物试验结果表明:胺类捕收剂对磷酸盐和硅酸盐矿物均具有较好的捕收能力;通过改变药剂加入量,调整其选择性,可更好地分离磷矿物与脉石矿物.
Abstract:
To desiliconize in reverse flotation of phosphate, it is important to select appropriate amine collector and reasonable conditions. In this paper, we compared the performance of coco diamine, diammonium hydrogenphosphate, dodecanamine and aliphatic amine 86D in flotation of collophane by HaLimond tube test. The result of pure mineral test shows that the flotation properties of different amine collectors are different, and the same amine collectors have different flotation properties under various pH values; the properties in collecting collophane of dodecanamine are better than that in coco diamine and diammonium hydrogenphosphate, and aliphatic amine 86D which has longer carbon chain performs worst at low dosage and mild acid medium; under the same pH value, aliphatic diamine performs better than aliphatic amine with the same carbon chain, and aliphatic amine with short carbon chain performs better than the one with long carbon chain; amine collector performs better in basic medium than in acid medium. The result of the actual mineral shows that amine collector performs well in collecting cellophane and silicate mineral; phosphate is separated from gangue mineral well by modifying the dosage and selectivity of agent.
