CAS 497-19-8 Na2CO3
Light or dense soda ash for pH control in flotation and cyanidation circuits, and water alkalinity adjustment.
pH modifier in flotation and gold cyanidation circuits; water treatment alkalinity/hardness adjustment; industrial and glass-grade applications.
It raises pulp pH and helps protect free cyanide from decomposing into toxic HCN gas, working alongside lime as an alkalinity source.
Same chemistry (Na2CO3), different bulk density and particle size — dense grade is more common in mineral processing for easier handling and dosing.
Yes — it's also used to adjust alkalinity and hardness in water treatment applications outside mining.
