Lithium Borate Fusion
Alkaline fusion with borate flux decomposes most refractory mineral types, enabling analysis of major oxides. When combined with Loss on Ignition (LOI) determination, an approximation of the whole rock matrix composition can be made.

Sodium Peroxide Fusion
This highly oxidizing, low temperature fusion is required for sulphide minerals and complete recovery of base-metal oxides.
