  • Cassiterite Flotation - Tin Oxide - 911 Metallurgist

    Jul 06, 2015  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.

  • Floatation agent for Cassiterite removal

    For the flotation of Cassiterite a common flotation agent is styrene phosphonic acid (SPA). The acid SPA is sparingly soluble in water and therefore offered as powder. For the production of aqueous solutions, a neutralisation with caustic soda (liquid or solid – corrosive, dangerous good!) is required.
