Problems solved by technology

It is relatively easy to use oxygen-containing air to remove copper, precious metals, iron, zinc, lead, etc. in impurities other than nickel, but it is difficult to remove antimony. If it is necessary to obtain blister copper that reaches the copper anode grade, nickel or The transfer efficiency of valuable metals such as precious metals to slag becomes high and it is difficult to effectively remove impurities

Abstract

The objective of the invention is to provide a method for processing and refining copper and material containing copper with high quality and efficiency from industrial waste, valence waste containing copper. The method for processing and refining materials containing copper at least includes: melting and reducing valence materials containing copper, noble metal, nickel, Fe, Sb with solvent and coke in a coke bed furnace of a straight-up furnace, a first working procedure of separating melt metal containing Cu and Fe as main components with slag containing calcium oxide, silicon dioxide, alumina and ferric oxide as main components, and a second working procedure of taking out melt metal generated in the first working procedure to a calcar of next working procedure, adding calcium carbonate into the melt metal in the calcar, insufflating gas containing O2 to the melt metal, making main impurities, such as Fe, and the like into slag, and taking out from the furnace.

Description

Method for processing and refining copper-containing raw materials Technical field The present invention relates to an incineration ash that can be obtained from industrial wastes, wastes containing valuables such as copper, incineration of combustible valuable raw materials containing copper, precious metals, nickel, iron, antimony, etc., or containing copper and precious metals , Nickel, iron, antimony and other valuable raw materials, copper-containing intermediate raw materials produced from the non-ferrous metal smelting process, a processing method to recover refined copper. Background technique In the past, in reverberatory furnace type smelting furnaces, industrial wastes, wastes containing valuables such as copper, and combustible valuable raw materials containing copper, precious metals, nickel, iron, and antimony were melted together with iron sulfide. The obtained incineration ash or valuable raw materials containing copper, precious metals, iron, nickel, antimony,...
