WebbSelective Leaching – Selective Corrosion. Selective leaching or selective corrosion is the removal of one element from a solid alloy by corrosion process. The most common example is the dezincification of brass, in which zinc is selectively leached from a copper–zinc brass alloy. This process produces a weakened porous copper structure. WebbRoasting is frequently followed by leaching with water or acid solutions to remove impurities made soluble by roasting. After appropriate preparation, the furnace feed for smelting comprises tin oxide and some impurities, including iron oxides, that were not removed in mineral processing or roasting.
