Anhydrous borax is white solid crystalline product used in gold smelting as a flux.
The advantages of using borax in gold smelting are:
- Facilitates separation of the gold from gangue at lower temperatures
- Borax forms a structural network with rock silicates that captures metal ions which normally associate with oxides eg. Calcium, iron, magnesium and aluminium. These in oxide, silicate or sulphate form are usually the major constituents of gangue
- Borax makes slag more fluid and thus increases the life of crucibles.
Application
Up to 70% of fluxing material can be made up borax. However most operations use 20-40%. Other fluxing agents normally used are silica flour, soda ash, nitre and manganese dioxide. The exact mix employed is a function of the type of ore used, economics of process – cost of energy and alternative fluxing agents.
