SOP Production Processes & Costs
The Company is targeting the deep brine aquifers for the potential of future PRIMARY SOP production.
This represents the lowest cost SOP production worldwide if successful in discovery
SOP is produced by three main processes:
1. Salt lake brine processing through evaporation and purification - organic
2. Secondary process of reacting MOP with sulfate salts
3. Mannheim process of reacting MOP with sulfuric acid
