Embodiment Construction

[0039] The current smelting method for non-ferrous metal regenerated materials containing lead, zinc, copper, gold, silver and rare precious metals is: first use a reduction furnace to reduce crude lead (and enrich a large amount of gold, silver and other rare and precious metals); Water-quenched water-quenched slag is sent to the rotary kiln to volatilize and extract zinc oxide (or directly hoist the slag bag into the fuming furnace to recover zinc oxide without water-quenching); The separated poor matte is sent to the matte furnace to be enriched into rich matte, and then the rich matte is sent to the converting furnace to be blown into blister copper. The technological process of each process is summarized as follows:

[0040] 1. The process flow of the reduction furnace process is as follows:

[0041] Such as figure 1 As shown, the materials from each silo are mixed and put into the oxygen-enriched side-blown reduction furnace for smelting. Crude lead (enriched in a lar...

Abstract

The invention relates to a comprehensive recovery device and process for various nonferrous metal materials. According to the comprehensive recovery device for the various nonferrous metal materials, a reduction furnace, a fuming furnace and a converter which are used for working procedures of recovering lead, zinc and copper are connected into a whole through thermal insulation external crucibles. The process has the characteristics of feeding at a time and continuous output of lead bullion, raw copper and zinc oxide. The comprehensive recovery device and process have the beneficial effects that raw materials are input at a time, all valuable metalsare extracted and purified, the working procedure of smelting is omitted, the production cycle is shortened, and the smelting process is simplified; heat energy in the smelting process is fully used, heat energy is greatly saved, and energy consumption is reduced; and the cost is saved for enterprises, the economic benefits are increased for the enterprises, the production cost is lowered for the enterprises, and the one-time fixed asset investment is reduced for the enterprises.

Description

technical field [0001] The invention belongs to the field of metal smelting, and in particular relates to a comprehensive recovery equipment and process for various nonferrous metal materials. Background technique [0002] There are two methods of smelting recycled materials containing lead, zinc, copper, gold, silver and other non-ferrous metals, including pyro-smelting and hydro-smelting. The international hydro-smelting process is not yet mature and is in the experimental stage. Therefore, the smelting methods at home and abroad all adopt the pyrometallurgy process. [0003] At present, different smelting furnaces are adopted at home and abroad according to the characteristics of each metal, and they are built into independent smelting and recycling processes, and a metal is recovered in one process. Lead (copper) is recovered in the smelting process of the first oxygen-enriched side-blown reduction furnace, and then the poor matte precipitated and separated from the sla...
