About the role of grinding medium in preparation of matte for flotation separation

Article preview

Investigations have been carried out into the grindability of high-grade matte in various types of mills. Differences in the character of grinding by means of rods, balls and cilpebs are shown. Recommendations for increasing the productivity of mechanical grinding are given.

Methods of Nickel Powder Production

Article preview

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.
