摘要:
针对传统脂肪酸捕收剂选择性差、常温下分散性和溶解性差的问题，以工业棉籽油酸为原料，经高温高压使脂肪酸的双键水解而引入羟基活性基团，进一步与助剂按比例复配得到一种高效反浮选捕收剂HY.将其用于宜昌某高镁磷矿的浮选试验，经一反一扫简单浮选工艺流程获得了精矿五氧化二磷品位34.59%，五氧化二磷回收率96.46%，氧化镁品位0.28%的良好浮选选指标，氧化镁脱除率高达95%，各指标优于公开招标各项指标要求，且浮选在常温下进行，药剂用量仅0.84 kg/t.表明反选捕收剂HY具有良好的浮选性能，其化学修饰改性改善了捕收剂的常温溶解性同时增强了其对钙离子、镁离子的选择性.
Abstract:
Aimed at the bad selectivity, poor watersolubility and intolerant at low temperatures of conventional fatty acid carbonate flotation collector, an efficient reverse flotation collector HY was synthesized using industrial cottonseed acid as the raw material, which was doublebonding hydrolyzed under high temperatures and high pressures to introduce hydroxyl active group and was compounded with additive in a certain percentage. The HY was applied to the flotation test in Yichang high magnesium phosphate ore. The concentrate grade of phosphorus pentoxide was 34.59%, the recovery of phosphorus pentoxide was 96.46%, the content of magnesium oxide was 0.28%, the removal rate of magnesium oxide was up to 95% with simply flotation process and 0.84 kg/t reagent dosage under the normal temperatures. The flotation result is better than the open tender requirements of the indicators, and shows that the reverse flotation collector HY has better flotation performance, watersolubility and selectivity for calcium ions and magnesium ions under the normal temperatures.
