Cadmium

Standard:GOST 1467-93

Production cycle:

leaching the copper-cadmium cakes, with the transfer of cadmium into solution;
cementation of the solutions by zinc powder to obtain the cadmium sponge;
dissolution of the cadmium sponge in the sulfuric acid solution;
electrolysis of the cadmium-bearing solution to produce the cadmium cathode;
re-melting the cadmium cathodes with obtaining the cadmium ingots.

Application range: The metal cadmium is used to produce alloys for electrical engineering, machine building, for anticorrosive coating of metals, in atomic industry, and to make nonorganic coloring matters.

Form and packing: The ingot cadmium has a mass of (10.0 ± 1.5) kg, with the placing on pallets. Each ingot must be marked: trademark of the manufacturer, cadmium brand, and the lot number.

The metal cadmium is produced in line with GOST 1467, brands: Кд0А and Кд0.

brand Кд0А, Cd – 99.98%

brand Кд0А, Cd – no less than 99.96%
