Abstract:
    The invention relates to a positive-negative floatation technology for cellophane, which comprises the following steps: subjecting siliceous-calcareous collophane ore to breaking and grinding process to dissociate ore monomer; adding water to it get ore pulp with concentration of 20 -50%; Leading the mixture to agitated tank; adding modifying agent sodium silicate and positive collector agent to ore pulp; processing the mixture in positive floating system to get foamed product; adding negative floatation agent inorganic acid and collector agent to the foamed product in negative flotation agitated tank; processing the mixture in negative floating system with carbonate vein mineral negative flotation to get foamed product as negative flotation debris and product in tank as clean ore. The invention can simplify process, deduce cost and recycle the water.
