A technology has been developed for production of Co, Ni, Fe, Cr, W, Ca, Ti, and other metals in the form of powders with grains less than 20 µm in size. The fineness of the powder grains can be varied on the customer's request.

The starting materials are halogenide salts, oxides, and mixtures of halogenide salts and oxides of the aforementioned metals.

The technology has been worked through in the laboratory conditions. An electrolyzer has been de-signed for metal powder production of up to 100 kg/day. Production of metal powders can be arranged in any capacity, from 1 kg to hundreds of tons.

ADVANTAGES

• 100-% extraction of metal from the starting material.

• Environmentally friendly technology.

• Electric energy output of 90—230 kW-hr per one kilogram of cathode material; electric power supplies to auxiliary electrochemical facilities.

• Reprocessing of metal-containing salt and slag waste.
