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 ...

ESR is similar to VAR, except a slag material is feed between the VIM ingot and the crucible. The molten metal droplets pass through the slag. Impurities in the metal, such as sulfur, react with and are trapped in slag. This results in refining and increasing the purity of the ESR ingot. NETL can produce up to 8-inch diameter ESR ingots.

Apr 23, 2016. #2. No you will not be able to skim the base metals of the top of a melt to reduce the volume you are going to have to process. The molten metal will want to have a rolling action cause some stirring of the metals. It is not generally a good idea to melt your material like this into bars and then to process the material with nitric.
