Lime is used extensively in the recovery of gold and silver.

The Importance of pH in Flotation

The disadvantage of sodium silicate is that it disperses the gangue slime so thoroughly, if much of it is used, that it is impossible to settle the fine part of the tailing subsequently in thickeners or a tailing dam. Lime or some other flocculating reagent can be added to coagulate the slime but the amount needed is often prohibitive.Flotation Reagents - Mineral Processing & Metallurgy,In the table on the opposite page the 100% column refers to undiluted flotation reagents such as lime, soda ash and liquids with a specific gravity of 1.00.
