Abstract: A method of wiping hot dipped metal coated wire or strip, and an apparatus for performing the method, involving drawing the wire or strip upwardly from a bath of molten metal through a wiping bed located at the point of emergence from the bath, with an interference device being positioned adjacent the wire or strip below the surface of the molten bath such as to restrict the lamella flow of molten metal entrained by the moving wire or strip. The interference device wholly or partly surrounds the wire or strip and is located below the wiping bed, which bed in turn may be laterally confined or unconfined. The interference device may be of any convenient configuration such as in the form of a horizontally disposed flat plate provided with one or more slots, grooves or other apertures through which the wire or strip passes.

Abstract: A process for simultaneous electrodissolution and electrowinning of metals from simple sulphide minerals comprises establishing a cell having(i) an anode compartment or compartments containing a suspension of particulate sulphide mineral, the metal content of which is being selectively liberated by an oxidizing environment attributable to the anode;(ii) a cathode compartment or compartments in which the liberated metal values are electrolytically recovered;(iii) one or more ion permeable membranes, impermeable to the particulate solids in the suspension, separating the anode and cathode compartments;(iv) An electrolyte containing anions of soluble salt(s) of the said liberated metal or metals in both anode and cathode compartments;introducing direct electric current into the cell, and recovering metal values from the cathode.
