Ure's description of the smelting process at Swansea, 1861. In 1861, Ure described the smelting processes used in Swansea. The predominant ores were cupreous pyrites and "gangue" (iron ore or rock), containing nearly equal parts of sulphide of copper and sulphide of iron. The processes were described as follows: 1. Calcination of the ore.
