Abstract
The present invention generally relates to a formulation created by reacting sodium hydroxide, water, and silicon metal which has unique properties and many uses. The present invention further relates to the separation of fine particle gold and other precious metals from clays and other gangue materials through application of a diluted solution of a silicon chemical. The present invention further relates to the use of the diluted solution of the silicon chemical with vibration tables, concentrators, wash towers, hydro-cyclones and centrifuges and the like to aid in the separation of fine particle gold and other precious metals from clays and other gangue materials.
