Zinc smelting

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 eg iron because in contrast zinc has a low boiling pointAt 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...

Discussion and Conclusion

For example when separating the iron salt and sand mixture we were able to use a magnet to remove the majority of the iron from the mixture This form of physical separation works because even though the components are mixed together they retain their own characteristics so iron remained magnetic even though it was a part of the mixture...
