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. WebbResidual Ore Deposits - substances are concentrated by chemical weathering processes. During chemical weathering and original body of rock is greatly reduced in volume by the process of leaching, which removes ions from the original rock. Elements that are not leached form the rock thus occur in higher concentration in the residual rock.
