Cassiterite flotation is nearly always performed in an acid environment, the exact value depending on the ore source and collector to be used. Sulphuric acid is used for pH adjustment in most cases. Changes in pH can cause changes to the froth. A reduction in pH will give better selectivity but usually at a lower recovery.Web
