我厂处理高鎢錫砷硫等矿,曾经使用枱浮选矿作业进行脫硫。枱浮設备是4500×1800公厘普通搖床。由于橡皮布制的床面不能抗酸,在实际生产中使用不到20天床面就要起泡,卽影响生产又不經济。現在改用生漆代替橡皮布做床面,经生产实踐証明,这种生漆床面不仅能耐酸,并且也符合技术上的要求。这种生漆床面每平方公尺的用料为:淨生漆1(1/2)市斤;西烟1/16市斤;石墨10/16市斤;水砂紙1/4張。制作程序是:先靠板漆1次后放夏布;再刮漆灰3次;磨光加漆2次后完工。同时应该注意在每次加工后必须干 I plant processing tungsten tungsten arsenic sulfur and other mines, Taiwan flotation beneficiation operations have been used for desulfurization. Floating equipment is 4500 × 1800 mm ordinary shaker. As the blanket made of the bed can not be acid-resistant, less than 20 days in the actual production of the bed will have to foam, 卽 affect the production and not economical. Lacquer is now used instead of blankets instead of bed, the production proved that this lacquer bed not only acid, but also meet the technical requirements. This raw paint bed per square meter of materials used: net lacquer 1 (1/2) jin; West smoke 1/16 jin; graphite 10/16 jin; water sandpaper 1/4. Production process is: first by the plate after the release of summer cloth; then scraping the paint 3 times; polished plus paint 2 times completed. At the same time it should be noted that after each processing must be dry
