(1) pH之定義及表示法在浮選上除了過去谈過的黄藥與松根油外,鑛液的酸碱性亦有很重要之關係,其原因有二:第一 鑛物因浮游度之不同,有的在酸性鑛液中浮游,有的在碱性中浮游,因此在浮選時一定要加以调整,使鑛物有适当的酸碱性,以充分發揮浮游力。第二酸性鑛液处理时,对 (1) Definition and representation of pH In flotation, in addition to the xanthones and pine root oils mentioned in the past, there is also a very important relationship between the acidity and the alkalinity of mineral liquids for two reasons: Different, some in the acidic mineral solution in the planktonic, and some floating in the alkaline, it must be adjusted in the flotation, the minerals have the appropriate acid-base, in order to give full play to the floating force. Second acidic mineral processing, right
