一、前言一、1955年曾以硫化钠作为铜钼分离浮选上的抑制剂进行了两种不同铜钼鑛石的二次小型试验,并经工业生产证明:以硫化钠单独或与氰化物合用作为铜钼分离的抑制剂,元论在经济指标上或技术操作指标上,均优于目前之单独使用氰化物。东北鑛山在1950年,曾以氰化钠作为铜钼浮选上的铜抑制剂。1955年以该鑛石先后用氰化物与硫化钠分别进行试验,结果看出;氰化钠的药剂使用成本要高于硫化钠的二倍以上;同时硫化钠作抑制剂
I. Preface I. The second small-scale experiment of two different copper-molybdenum ores with sodium sulfide as the inhibitor on flotation separation of copper and molybdenum was conducted in 1955 and proved by industrial production that sodium sulfide alone or in combination with cyanide Combined as an inhibitor of copper and molybdenum separation, the metamorphosis is superior to the current use of cyanide alone in economic indicators or technical operation indicators. Northeast mine in 1950, had sodium cyanide copper copper molybdenum flotation on the copper inhibitor. In 1955, the ore was tested with cyanide and sodium sulfide respectively. The results showed that the cost of using sodium cyanide was more than twice that of sodium sulfide; meanwhile, sodium sulfide was used as inhibitor
