腐植酸钠(以下简称腐钠)是一种黑色粉末或黑亮色颗粒,易溶于水、无毒、无怪味。云南煤炭化工厂出品的腐钠,水可溶腐植酸含量>70％,水不溶物≤2％,水分≤15％。在浮选烂泥坪矿石中,用腐钠作为铜矿石的抑制剂,进行几次小型试验、工业试验及工业生产试验,均表明它能有效地抑制硅、铝等脉石,在回收率保持不下降的情况下,可提高精矿品位。按该厂年计划产铜计算,精矿品位提高2％,每年净增14万元。 Sodium humate (hereinafter referred to as rotten sodium) is a black powder or black bright particles, soluble in water, non-toxic, no smell. Yunnan coal chemical plant produced sodium, water-soluble humic acid content> 70%, water insoluble matter ≤ 2%, moisture ≤ 15%. In the flotation of khamping ores, the use of sodium as an inhibitor of copper ores, several small-scale tests, industrial tests and industrial production tests have shown that it can effectively inhibit the silicon, aluminum and other gangue, the recovery rate to maintain Do not drop the case, can improve concentrate grade. Calculated according to the plant plan copper production, concentrate grade increased by 2%, annual net increase of 140,000 yuan.
