印度的铜铅锌选矿工业有许多优点,如井下粗碎、使用水力旋流器代替机械分级机与球磨机闭路、球磨机普遍使用橡胶衬板、浮选时混合用药、药耗少、浮选产品质量高、有用矿物回收率高等,这些都是值得我们借鉴的,因此译出下文,供有关同志参考。同时,该文中还列举了世界很多国家铅锌分离的药方,也是值得研究的。 India’s copper, lead and zinc beneficiation industry has many advantages, such as coarse crushing, the use of hydrocyclones instead of mechanical classifier and ball mill closed circuit, the ball mill commonly used rubber lining, mixed medication flotation, less drug consumption, flotation product quality High, high recovery rate of useful minerals, these are worth learning from, and therefore translated below, for the comrades for reference. At the same time, this article also lists the prescriptions of lead and zinc separation in many countries in the world and is also worth studying.
