大冶铁矿选矿试验室和沈阳冶金选矿药剂厂于1980年10月14～29日在大冶铁矿选矿车间进行了捕收剂“234”浮选铜硫工业试验。试验共处理原矿122001吨。结果表明,“234”捕收剂和Z-200捕收剂在用量相近情况下,获得相似的分选指标。“234”学名N-Z丙醚基-丁基硫逐氨基甲酸酯,分子式C_2H_5OC_3H_6NHSCOC_4H_9,是无毒高效捕收剂,对铜、锌、金、钼等金属矿物有良好的捕收性能,对黄铁矿捕收能力较差,适用多金属矿物的分离。大冶铁矿矿床是多金属矿床。主要矿物有磁铁矿、赤铁矿、菱铁矿、黄铜矿及少量辉铜矿、铜
Daye Iron Ore Dressing Laboratory and Shenyang Metallurgical Flotation Pharmacy Factory conducted “234” flotation tests for copper and sulfur in the Daye Iron Ore Dressing Workshop from October 14 to October 29, 1980. Test a total of 122001 tons of ore processing. The results show that “234” collector and Z-200 collector in the case of similar dosage, access to similar sorting index. “234” Scientific name NZ propyl ether-butyl sulfocarbamate, molecular formula C_2H_5OC_3H_6NHSCOC_4H_9, is non-toxic and efficient collector, copper, zinc, gold, molybdenum and other metal minerals have good harvesting properties, the yellow iron Mine collection capacity is poor, for the separation of polymetallic minerals. Daye iron ore deposit is a polymetallic deposit. The main minerals are magnetite, hematite, siderite, chalcopyrite and a small amount of chalcocite, copper
