Treating equipment for recycling lead, zinc and copper from tailings

Abstract

The invention discloses treating equipment for recycling lead, zinc and copper from tailings. The equipment comprises a ball mill, an activation bin, a collection bin, a restraining bin, a discharger,a conveying assembly and a control assembly. The top ends of the activation bin, the collection bin and the restraining bin are each provided with a liquid filler. The liquid fillers are provided with a first agent storage bin, a second agent storage bin and a third agent storage bin, zinc sulfate is contained in the first agent storage bin, carbon acetate, second oil and lime are contained in the second agent storage bin, carbon acetate, lime and sodium sulfite are contained in the third agent storage bin, the conveying assembly comprises an air pump and a conveying pipe, the control assembly comprises a processor, a weight sensor, a liquid level sensor, a liquid conveying amount sensor and an electromagnetic valve. Due to the design of adding zinc sulfate, the effect of an activating agent is achieved; due to the design of adding ethyl-sulfur carbon, the effect of a collecting agent is achieved; due to the design of adding second oil, the effect of a foaming agent is achieved; and due to the design of adding carbon acetate, lime and sodium sulfite, the effect of a restraining agent is achieved. The recycling efficiency of lead, zinc and copper is improved.

Description

technical field [0001] The invention relates to the technical field of tailings recovery, in particular to a processing device for recovering lead, zinc and copper from tailings. Background technique [0002] As we all know, copper, lead, and zinc are the main non-ferrous metals, and they are widely used in various fields of industrial or civil products. At present, the world's annual copper consumption is 20 million tons, China's is 5 million tons, and China's output is 2.5 million tons; the world's annual lead consumption is 7.1 million tons, China's is 1 million tons, and China's output is 1.5 million tons tons; the world's annual zinc consumption is 11 million tons, China's is 2.2 million tons, and China's output is 3 million tons. Therefore, in order to ensure domestic supply and external sales, the recovery of lead, zinc and copper from tailings Particularly important. [0003] In the existing process of recovering lead, zinc and copper from tailings, the recovery ac...
