Abstract

The invention relates to a mineral separating process for recovering useful components in tailings and particularly relates to a process for comprehensively recovering ferrum, molybdenum and sericite from gold concentrator tailings. The ferrum, molybdenum and sericite in the gold concentrator tailings are sufficiently recovered by using primary grinding, primary magnetic separation and secondary flotation processes, the recovery rate of Fe in the obtained magnetic concentrate is larger than 75%, the recovery rate of Mo in a molybdenum concentrate is larger than 70%, and the recovery rate of the sericite in a sericite concentrate is larger than 61%. The process provided by the invention is advanced, stable in operation and capable of increasing the utilization efficiency of resources of the gold concentrator tailings.

Description

technical field [0001] The invention relates to a process for comprehensively recovering iron, molybdenum and sericite from gold dressing tailings, which is especially suitable for comprehensively recovering iron, molybdenum and sericite from tailings in quartz vein type gold-bearing pyrite flotation. Background technique [0002] With the development and utilization of mineral resources, resources are becoming increasingly depleted, tailings as a secondary resource have received more attention, a large amount of tailings discharge not only covers a large area, but also pollutes the environment. Recovery of useful components from tailings is conducive to improving resource utilization efficiency, reducing floor space, and providing more raw materials for industrial development. Carrying out comprehensive utilization of tailings is one of the most promising development directions to improve the utilization efficiency of secondary resources. Gold beneficiation tailings have t...
