Abstract
1,224,059. Recovery of tin. INSTITUTO DE INVESTIGACIONES MINERO METALURGICAS. 24 May, 1968, No. 24921/68. Heading C1A. [Also in Divisions C6-C7 and F3-F4] Cassiterite containing tin concentrates, together with fluxes, are smelted on sloping hearth 6 of smelting zone 3 of a reverberating furnace, to produce crude molten tin withdrawn through taphole 7, and a molten slag containing tin oxide, which overflows into volatilization zone 4 in which a reducing atmosphere is maintained. Further low grade tin concentrates such as old slags and tailing washings, together with an excess of iron pyrite, elemental sulphur, pyritic tin concentrates or stanniferous iron pyritees, are introduced through chargehole 9 into zone 4 to form tin sulphide which, due to the furnace temperature, volatilizes. An air supply from inlet 10 then converts this volatilized tin sulphide to tin oxide which is recovered in powder form in a baghouse or electrostatic precipitator (not shown) downstream of duet 15, for recycling to zone 3 or conversion to the metal in a separate electric furnace. The residual slag withdrawn through taphole 11 is granulated and dumped. In a modification (Fig. 1, not shown), a regenerative reverberatory furnace is employed.
