Bismuth: extractionMetalpedia
Bismuth: extraction; Brife introduction; Bismuth is extracted from its ores by dry, wet, or electrometallurgical methods, the choice depending upon the composition of the ore and economic conditions; The dry process is more frequently practised, due to the easy reducibility of the oxide and sulphide, together with the low meltingpoint of the metal, which renders it possible to effect aThe ores of copper are usually associated with minerals containing arsenic, antimony and bismuthWhatever the means adopted for extracting the copper, these metals are usually found, to a greater or less extent, in the product There is, however, usually some elimination in the various metallurgical operations to which the ores are subjected, and some attempt is made here toHow to Remove Arsenic, Antimony & Bismuth from Copper
