secondary refining process of copper sheets


Posted on May 21, 2019



Copper Processing - P2 InfoHouseThe second method for refining copper is called the hydrometallurgical process. This process begins with oxidized copper ores or oxidized copper wastes. The oxidized material is leached with sulfuric acid from the smelting process. The sulfuric acid is percolated through piles of oxidized metal and collected with acid.secondary refining process of copper sheets,secondary refining process of copper sheets,Simplified flow sheet of black copper smelter process (secondary .See figure: 'Simplified flow sheet of black copper smelter process (secondary copper smelting) [59]..' from publication 'Metal Extraction .
