Abstract
Stanniferous materials low in gangue and containing zinc, such as ores, oxides, &c., are heated with a flux such as sodium carbonate under such conditions as to volatilize the whole of the zinc and part of the tin as oxides, the greater part of the tin remaining in the residue, which is afterwards treated for the recovery of the metals.ALSO:In a process for recovering tin from stanniferous materials low in gangue, such as ores, oxides, &c., containing or free from zinc, the material is mixed with a substance such as sodium carbonate or borax and carbon, and is heated in a muffle, electric, or other furnace, the temperature being so regulated as to preclude the formation of a molten slag, whereupon any zinc present distils off, and the tin and other metals are recovered in metallic form in the residues. In some cases the material is first preliminarily heated with a flux such as sodium carbonate under such conditions as to volatilize the whole of the zinc and a part of the tin as oxides, the greater part of the tin remaining behind, whereafter the residue is mixed with sodium carbonate and carbon and treated as above.
