Extraction Of Metals | Good Science

Only the least reactive metals, such as gold and silver, exist in their elemental metallic form. These metals are known as native metals. The chemical reactivity of metals also determines their method of extraction. Native metals undergo physical separation processes, such as froth flotation.

Separation And Recovery Of Components In A Ternary …

Mixtures can also be separated by chemical methods which involve selective reaction of one the of the components to form a new substance. The physical properties of the new substance can then be used toseparate it from the mixture. Once separated, a second reaction converts the new substance back to the original component.
