遵照伟大领袖毛主席“备战、备荒、为人民”的教导,为了降低丁基黄药用量,节约工业用粮,提高选矿指标,我们于一九七六年六月十四日至七月二十日在卡房前进矿进行了新型浮选捕收剂丁黄酸烯丙酯(简称OS—43)的工业试验。工业试验进行了80个小班,共处理矿石7266.94吨,工业试验的结果表明.在卡房前进矿现有条件下使用新药剂OS—43与丁基黄药混用,比单用丁基黄药时丁基 In accordance with the teachings of Chairman Mao, the great leader, “preparing for war, preparing for war and for the people”, in order to reduce the consumption of butyl xanthines, save industrial grain, and raise the ore dressing targets, we conducted the training from June 14 to July 2, On the 10th, a new type of flotation collector, allyl butyrate (OS-43), was industrially tested in advance at the kerbside. Industrial tests carried out 80 small classes with a total of 7266.94 tons of ore processed, the results of industrial tests show that the use of the new agent OS-43 in combination with butyl xanthate in the existing conditions in the card room forward mine, Butyl
