摘要:
磷矿反浮选捕收剂大多数是由天然脂肪酸制成的，种类繁多，性能各异.从市场快速、准确地选择磷矿反浮选捕收剂，对浮选实践和浮选研究十分重要.浮选捕收剂的评价有助于掌握捕收剂的浮选性能，了解其在浮选过程中的作用.浮选法是浮选捕收剂的传统评价方法，程序复杂，耗时耗力.提出了一种新的浮选研究方法：燃烧-吸附量评价法，通过燃烧无机的矿石样品来测定其表面吸附的有机捕收剂量，评价磷矿反浮选捕收剂的性能.通过对油酸、硬脂酸和软脂酸这些结构明确且浮选工作者熟悉的脂肪酸的浮选性能和在白云石上的吸附量，建立了一个评价模型，验证燃烧-吸附量评价法的可行性.
Abstract:
Most reverse flotation collectors for phosphate ores are made from natural fatty acids with considerable differences in origin and flotation performance. It is very important in both flotation practice and flotation research to make a rapid and accurate choice from the numerous collectors available on the market. The evaluation of a flotation collector is also important for the mastering of the collector’s flotation performance, and for the understanding its role in flotation process. Traditionally, flotation collectors are appraised through their flotation performance using flotation tests. But the procedure for flotation method is very complex and timeconsuming. Combustion of inorganic ore sample to determine the adsorption capacity of organic collector on ore surface is a newly developed method in flotation research. A new collector evaluation method for phosphate rock reverse flotation collector performance，namely combustionadsorption capacity evaluation method, was proposed. An evaluation model was constructed and appraised using collectors such as oleic acid, stearic acid and palmitic acid whose structure and composition are familiar to flotation workers, according their flotation performances and their adsorption capacity on dolomite. The feasibility of combustionadsorption capacity evaluation method in phosphate flotation was experimentally tested.
