Abstract

The invention discloses a method for smelting a lead-containing material, relating to the technological process for processing complex lead materials by utilizing a smelting method. The method is characterized in that a flash furnace and a depletion furnace are combined for smelting during the smelting process. The method of the invention has the advantages of short and continuous flow, energy saving, large capacity, efficient source utilization, environment protection, good safety and good industrial hygiene, no danger of foam slag exploration and safe production. The lead smelting process with high smelting strength and various advantages realizes single-step lead smelting, and has stronger adaptability on materials. The process is not only suitable for treating lead ore with complex components, but also suitable for treating wet smelting zinc slag, wet smelting copper slag and lead noble metal system slag, can do complementation of lead, zinc and copper and has more advantages overlead, zinc and copper jointed enterprises. The recovery rates of lead and concomitant valuable metals of copper, zinc and noble metals are higher.

Description

technical field

[0001] The invention discloses a smelting method for lead-containing materials, which relates to a technological process for processing complex lead materials by adopting a smelting method. Background technique

[0002] Lead is an important basic raw material for the development of the national economy. China is the world's largest lead producer and the second lead consumer after the United States. Lead smelting methods can be simply summarized into two categories: traditional method and direct lead smelting method. The traditional method is sintering-blast furnace smelting method (including sintering machine, sintering pot, sintering pan, etc.); the direct lead smelting method is a method in which the sintering process of lead sulfide concentrate is cancelled, and the raw concentrate is directly smelted in the furnace. The traditional sintering-blast furnace smelting method has been the main production method of lead for many years, and even now, its output...
