Abstract

The existing solid-phase methods of nickel powder production are described, their critical analysis is carried out and ways of improvement are indicated, allowing to obtain a significant economic effect. The results of tests of low ash solid reducing agent allowing to reduce slag output at anode electro-smelting are given. The method of nickel cinder reduction in tube furnaces is stated, which allows to obtain an active fraction of nickel powder with cementation activity over 80%, which opens up the possibility of its use for purification of nickel electrolyte from copper.
