Silver Mining and Refining Education

In this process, crushed ore is placed in a bath. Air bubbles are blown through the mixture to carry the silver to the top of the bath where it forms froth. The silver-rich froth is skimmed from the bath and smelted so that it can be separated from other metals. A diagram illustrating the froth flotation process.
