| Abstract: | A new copper collector, CYC-20, was introduced in the flotation tests of the associated copper minerals from a Shandong iron mine. A laboratory closed-circuit test resulted in a copper concentrate grading 17.20% Cu at 66.37% recovery, while the commercial test produced a copper concentrate grading 20.33% Cu at 73.03% recovery. The problem of xanthate ion content in tailings water exceeding the standard was also resolved. This practice has testified that CYC-20 is an excellent copper collector with good application prospect. |
