• Designing flotation circuits for high fines recovery

    · Our zinc circuit had never seen clean mineral surfaces before—they had always been masked by iron hydroxides from grinding, or gypsum precipitation from pulp, or simply oxidation after long flotation times in the lead circuit High collector additions to pulp were needed to diffuse through surface layers to get adequate mineral surface coverage But the IsaMills produced very clean mineral
