Abstract

Separating complicated linked fluorite and calcium-containing gangue minerals efficiently is challenging with a standard oleate (NaOL) collector due to its limited selectivity and flexibility. In order to improve the efficiency of separating fluorite ore through flotation, a new collector called (E)-N-(2-hydroxyethyl)octadec-9-enamide (NOE) was created and compared to the standard collector sodium oleate (NaOL). The experimental results indicate that the optimal pH for flotation is 9, while the optimal dosages of NOE and NaOL are 150 g/t and 300 g/t, respectively. During bench-scale flotation studies, the use of a novel collector (NOE) at half the dose of the usual collector NaOL (175 g/t compared to 350 g/t) resulted in a 9.15 % improvement in the recovery of fluorite.

使用(E)-N-(2-羟乙基)十八-9-烯酰胺作为浮选捕收剂对萤石矿进行浮选分离

由于标准油酸酯（NaOL）捕收剂的选择性和灵活性有限，因此高效分离复杂的萤石和含钙杂质矿物具有挑战性。为了提高浮选分离萤石矿的效率，我们创造了一种名为(E)-N-(2-羟乙基)十八-9-烯酰胺（NOE）的新型捕收剂，并将其与标准捕收剂油酸钠（NaOL）进行了比较。实验结果表明，浮选的最佳 pH 值为 9，NOE 和 NaOL 的最佳用量分别为 150 克/吨和 300 克/吨。在台式浮选研究中，使用新型捕收剂（NOE）的剂量是普通捕收剂 NaOL 的一半（175 克/吨，而 NaOL 为 350 克/吨），因此萤石的回收率提高了 9.15%。
