New Flotation Machine Developed
Pyongyang, April 13 (KCNA) -- Scientists of the Research Institute of Mining Machinery under the State Academy of Sciences have developed a new kind of pillar flotation machine.

The air machine makes it possible to collect useful minerals contained in low-grade ores and residue and enhance actual concentration rate.

It, which needs a small area for its installation and has a large capacity, is low in both the manufacture and operation expenses. It is also less in electricity consumption and much longer in serviceable life than the existing one.

It is also available for slag concentration at thermal power stations.

The new machine has already been introduced at dressing plants.
