Abstract

The invention discloses a copper matte bottom blowing converting process and a copper matte bottom blowing converting furnace. The copper matte bottom blowing converting process comprises the following steps: adding copper matte and non-alkaline flux into the copper matte bottom blowing converting furnace, blowing oxygen-containing gas continuously into melt in the copper matte bottom blowing converting furnace from the bottom of the copper matte bottom blowing converting furnace with a bottom blowing spraying gun, and discharging blister copper and converting residue from the copper matte bottom blowing converting furnace. According to the copper matte bottom blowing converting process and the copper matte bottom blowing converting furnace, continuous converting of the copper matte can be realized, less fume is produced, the SO2 concentration is stable, the environment is well protected, the efficiency is high, and the blister copper and sulfuric acid are low in production cost.

Description

technical field [0001] The invention relates to the technical field of nonferrous metallurgy, in particular to a copper matte bottom-blowing converting process and a copper matte bottom-blowing converting furnace. Background technique [0002] The metallurgical methods of copper are divided into fire method and wet method. The technological process of pyrometallurgy copper smelting is mainly to obtain copper concentrate after flotation of copper sulfide concentrate, and then smelt it in electric furnace, flash furnace and other smelting furnaces to obtain copper matte , The copper matte is blown to obtain blister copper, the blister copper is fire-refined to obtain anode copper, and then electrolytically refined to obtain electric copper. At present, PS converter is usually used for blowing of copper matte. Liquid copper matte is added into PS converter, and oxygen is blown from the side of PS converter to obtain blister copper and blowing slag. After one batch of copper ma...
