Tin processing | BritannicaThe most important of these is in Southeast Asia and includes the tin-mining areas of China—which accounted for nearly half of all tin production in the early 21st century. Myanmar . This process produces a pool of molten tin, on top of which floats a slag containing most of the unwanted impurities. At the completion of.processing mining slags,Slag - WikipediaSlag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic. A good example is steelmaking slag:.
