Tin material fuming method using natural gas as fuel

The invention discloses a tin material fuming method using natural gas as fuel. The tin material fuming method specifically comprises the following steps: (1) adding a low-tin material, a flux and a vulcanizing agent into a fuming furnace; (2) carrying out fuming treatment by taking natural gas as fuel of a fuming furnace and taking combustion-supporting air as combustion-supporting of the natural gas; (3) introducing the tin-rich flue gas into a waste heat boiler; (4) introducing the tin-containing flue gas into a surface cooler; (5) performing smoke granulation on the boiler smoke and the surface cooling smoke; (6) introducing the surface-cooled flue gas into a cloth bag dust collector; (7) carrying out dust granulation on the dust in the cloth bag; (8) treating the tail gas of the cloth bag, and discharging after reaching the standard; (9) carrying out water quenching on the slag; and (10) loading and weighing to obtain tailings for resource utilization. The invention provides the method for smelting in th
