三年前,我们开始试验粒浮白钨时,采用油酸作为捕集剂。但油酸本身具有某些缺点,使选别效率不能令人满意。后来,发现菜油比油酸本质优良,适宜浮选白钨;价格较廉,及可就地取材等优点,就采用菜油浮选白钨,选别效果很好。据了解,中南有的选矿厂,也是采用菜油浮选白钨的。但是,菜油是人民生活中必不可少的一种主食品,因此大量消耗食油是不恰当的。在这种情形下我
Three years ago, we started experimenting with levulinic acid, using oleic acid as a collector. However, oleic acid itself has some disadvantages, making the sorting efficiency unsatisfactory. Later, it was found that vegetable oil is superior to oleic acid in nature and is suitable for flotation of scheelite; its advantages are relatively low price and availability on the spot.

However, vegetable oil is an indispensable staple food for people’s lives, so it is not appropriate to consume a large amount of cooking oil. In this situation, I
