前言关于氯化钠的捕收剂,国外近年来陆续有过报导。我国可溶盐矿物资源丰富,但并没有开展过氯化钠的捕收剂研究工作。使用合成氯化钠的捕收剂,浮选分离除去混合盐矿中的氯化钠,以利于光齿石、钾盐镁矾等矿物进一步加工,这是盐类加工的新途径。本实验合成的N-烷基吗啉和脂肪酰胺两类捕收剂,可分别从察尔汗盐田光齿石矿、 Preface About sodium chloride collector, foreign countries have reported in succession in recent years. China is rich in soluble salt mineral resources, but has not carried out sodium chloride collector research. The use of synthetic sodium chloride collector, flotation separation of mixed salt and remove the sodium chloride, in order to facilitate the light tooth stone, potassium and other mineral magnesium ore further processing, which is a new way of salt processing. The experimental synthesis of N-alkyl morpholine and fatty acid amide two kinds of collectors, respectively, from Chaerhan Yantian Guangde quarry,
