| titleOfInvention | Beneficiation method for associated low-grade gold and cobalt in iron ore |
| abstract | The application relates to the technical field of ore dressing, in particular to an ore dressing method for associated low-grade gold and cobalt in iron ore. The method mainly comprises the following steps: a roughing step, namely obtaining gold-cobalt mixed rough concentrate and first tailings; grinding: grinding until the fineness of the rough gold-cobalt mixed concentrate is less than 10 mu m and accounts for 70-90 wt%. Gold concentrate beneficiation step: obtaining gold concentrate and gold scavenging tailings; and (3) cobalt concentrate beneficiation: and obtaining the cobalt concentrate. The method provided by the application adopts the step of grinding in sections, selective separation, and by utilizing the floatability of minerals, under the condition of a coarse granularity, the gold-cobalt minerals are separated from iron ores in a roughing mode, the gold-cobalt minerals are floated out, then the gold-cobalt minerals with complex embedding relations are subjected to superfine grinding and regrinding, the monomer separation of the gold and the cobalt is realized, and the step of grinding in sections can effectively reduce the grinding energy consumption and strengthen the gold-cobalt separation degree. Realizes the comprehensive recovery of associated gold and cobalt. |
