Abstract

1420455 Coated particles NORDDEUTSCHE AFFINERIE 11 April 1973 [19 April 1972] 17520/73 Addition to 1326813 Heading B2E [Also in Division C7] Foamed particles of polystyrene or polyurethane have porous coatings including stannic acid (SnO 2 aq) in a mixture of binders. The particles are employed in the purification of a solution which has been used in the electrolytic refining of Cu and contains As, Sb and/or Bi impurity (see Division C7). The stannic acid is applied to the polystyrene or polyurethane as a solution or suspension containing (a) a water insoluble binder based on an acrylic ester in the form of a homopolymer or of a copolymer with a vinyl ester, styrene, a vinyl ether, vinyl chloride, or vinylidene chloride; (b) a water soluble or water swellable binder based on polyacrylates, polyacrylic esters acrylic ester copolymers, polyacrylamides or polyethylene imines; (c) poreforming substances such as sugar, urea, chlorides, sulphates or acetates which can be dissolved out and/or sulphites, bicarbonates or carbonates which decompose with evolution of gas when heated or are decomposed by acid; and (d) substances to prevent ropiness of the solution or suspension such as monomeric or polymeric amines or amino alcohols which also act as plasticizers.
