Zinc smelting

10 ensp 0183 ensp Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure zinc Zinc smelting has historically been more difficult than the smelting of other metals e g iron because in contrast zinc has a low boiling point At temperatures typically used for smelting metals zinc is a gas that will escape from a furnace with the flue gas and be lost unless specific

Roasting of Gold Ore in the Circulating Fluidized Bed

The degree of SO 2 capture in the CFB shows a high degree of temperature dependence The sorbent demand increases if the combustion temperature is outside the optimum range of about 800–850 176 C The temperature effect can be attributed to insufficient calcination at lower temperature and possibly to a faster pore mouth closure that limits SO 2 diffusion to the inner sorbent surface at
