Zinc

Standard:GOST 3640-94

Production cycle:

roasting the sulfide zinc concentrates in fluid-bed furnaces;
leaching the zinc cinders and oxides with obtaining the zinc solutions and zinc cake;
rotary-kiln operation for zinc cakes with producing the zinc oxides;
clarification of zinc solutions;
electrolysis of neutral clarified zinc solutions;
re-melting the cathode zinc to obtain ingots.

Application range: Galvanic coating, medicine, production of zinc-bearing alloy, production of paint and varnish items, machine building, construction, etc.
