Problems solved by technology

However, whether it is lead ore smelting or waste lead recovery and smelting, the refined lead slag derived from the smelting process generally contains 8%-10% lead, 8%-18% antimony, 20%-30 % reduction, for the refined lead slag that has not reached the standard discharge standard stipulated by the national environmental protection department, the enterprises mostly pile them up in a centralized manner, and do not perform harmless treatment

Abstract

The invention discloses a device and method for separating lead, antimony slag and alkaline liquor from lead-refined alkali slag by using a one-step method, which relate to the technical field of lead ore smelting. The device and the method are mainly applied to waste refined lead slag of derivatives in the lead ore smelting process and waste lead recovery smelting and renewable resource smelting process and further can be used for separating and extracting the lead, antimony slag and alkaline liquor contained in the waste refined lead slag. The hazardous waste refined lead slag generated in the lead ore smelting process, waste lead recovery smelting and renewable resource smelting process is comprehensively utilized, thus the risk of pollution to the environment is eliminated, a higher economic benefit is obtained, and the comprehensive and effective utilization of refined lead slag derived in the smelting process of the lead is realized.

Description

technical field [0001] The invention relates to the technical field of lead ore smelting, in particular to a device and method for separating lead, antimony slag and lye in one step from lead refining alkali slag. Background technique [0002] Lead is widely used in pillar industries such as national defense construction, chemical industry, printing and dyeing, automobile, communication, etc. It is a basic material closely related to industrial development and people's life. Due to the limited resources of lead ore, various countries pay more attention to the recycling and recycling of lead-containing waste while mining lead ore. However, whether it is lead ore smelting or waste lead recovery and smelting, the refined lead slag derived from the smelting process generally contains 8%-10% lead, 8%-18% antimony, 20%-30 % reduction, for the refined lead slag that has not reached the standard discharge standard stipulated by the national environmental protection department, ente...
