Method for recovering co-produced low-grade valuable elements from lepidolite flotation concentrate using atmospheric pressure alkaline leaching method

Abstract

The present disclosure discloses a method for recovering co-produced low-grade valuable elements from a lepidolite flotation concentrate using an atmospheric pressure alkaline leaching method, and belongs to the technical field of lithium, rubidium, and cesium resource recovery and recycling. The present disclosure adopts an atmospheric pressure alkaline leaching method to recover valuable elements such as lithium, rubidium, and cesium in a lepidolite flotation concentrate, and lithium, rubidium, and cesium are green and have an efficient synergistic leaching rate. In response to the problems such as resource waste, high energy consumption, and secondary environmental pollution caused by the prior art, there is provided efficient synergistic recovery of lithium, rubidium, and cesium in lepidolite ores using high reactivity provided by a non-conventional alkali medium. The process flow of the present disclosure is less time consuming, the equipment operation is simple and safe, the lithium, rubidium.
