It is shown that mixed tolyl arsonic acid was much superior to either para- or ortho-isomer alone for cassiterite flotation. Mixing ratios between paraand ortho-tolyl arsonic acids ranging from 50:50 to 30:70 were effective with a peak value at 45:55 in which a maximum collecting capacity was obtained. The preparation of mixed tolyl arsonic acid was more convenient than that of paraisomer, a conventional collecting agent for cassiterite flotation. In the plantscale flotation of cassiterite slimes assaying from 0.6 to 0.7 percent Sn, tin concentrates with the grade of about 25.65％ were obtained, the total recovery being about 58.64％. Cassiterite flotation using mixed tolyl arsonic acid as collectors and sodium carbonyl methyl cellulose as despressing agents for calcite have already been put into industrial practice. 收稿日期: 1978-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I1/17 [1] Topfer, E., Freiber.
