Abstract

The invention discloses a zinc leaching slag treatment device and a zinc leaching slag treatment process using the same. The zinc leaching slag treatment device comprises a primary side-blown converter and a secondary side-blown converter, wherein the primary side-blown converter is used for smelting zinc leaching slag, and provided with a first furnace body and a first side-blown spray gun for blowing oxygen-containing gas and fuel into the first furnace body; and the secondary side-blown converter is used for smelting molten slag generated by the primary side-blown converter, and provided with a second furnace body connected with the first furnace body through a hot slag chute, and a second side-blown spray gun for blowing oxygen-containing gas and fuel into the second furnace body. The zinc leaching slag treatment device and the zinc leaching slag treatment process using the same have the advantages of low energy consumption, low production cost and high recovery rate of zinc, lead, silver and dissipated metals, and can improve the operating environment.

Description

technical field [0001] The invention relates to a treatment device and process for smelting nonferrous metals, especially zinc leaching slag. Background technique [0002] At present, the commonly used zinc leaching slag treatment process is the rotary kiln volatilization method. However, the rotary kiln volatilization method has obvious disadvantages, such as low equipment capacity, short furnace lining life, high comprehensive energy consumption, expensive coke, large equipment footprint, poor operating environment, and other valuable zinc leaching slag. Metals such as silver, indium, germanium and other valuable metals have a low recovery rate. Contents of the invention [0003] The present invention aims at solving the above-mentioned technical problems at least to a certain extent or at least providing a useful commercial choice. [0004] For this reason, the first object of the present invention is to propose a zinc leaching slag treatment device, which can perform...
