Recovering Low-Grade Precious Metals

     

The method for recovering low-grade precious metals from beneficiation tailings includes the following steps: flotation of raw tailings, gravity separation with a Knelson concentrator, oxidizing roasting pretreatment of Knelson tailings, and cyanide leaching of roasted slag.

Tailings flotation enriches gold into flotation concentrate, which is then processed by Knelson concentrator gravity separation to further recover the coarse-grained gold contained therein. The Knelson tailings are pretreated via oxidizing roasting, and the obtained roasted slag is treated with the cyanide leaching process to recover the micro-fine grained gold lost in the Knelson tailings.

This method realizes gold recovery in stages and improves the gold recovery rate. It solves the problem of low precious metal recovery rate when treating flotation tailings with traditional processes, and further lifts the recovery rate of precious metals. Meanwhile, it produces both gold concentrate and iron concentrate, which improves the comprehensive utilization rate of tailings. It also achieves zero discharge of solid waste, completely eliminates the impact of tailings ponds on the surrounding environment, and removes pollution sources and potential safety hazards.
