How to Obtain Arsenic

Obtain arsenic as a by-product of mining and refining other metals Recover the flue dusts produced from copper nickel and tin which are high in the arsenides of these metals Heat them in air to sublimate the arsenic and cool the gas to condense the arsenic back into a solid This method accounts for most of the arsenic production in the world
