What is refining and how liquation process is used for refining of metals? |
|
Answer» The process of purifying the crude metals is called refining of metals. Low melting metals like tin and lead are refined by liquation since the melting points of these metals are lower than those of refining. The impure metals are melted on a sloping hearth of a furnace. Pure metals melt earlier than impurities and flow on the loping surface leaving behind the unmelted impurities. |
