The Unpha Mine is solving the problems arising in installing air flotation machine capable of increasing the existing capacity of dressing plant 1.3 times, in cooperation with scientists of a relevant research unit.

It has introduced scientific and efficient working methods to provide enough cutting faces and put spurs to introducing a technical innovation plan to further improve the performance of tunneling and drainage equipment.

Apatite mines are increasing the production of minerals by carrying out a technical research task in a higher level while consolidating the successes achieved in locally producing ore-dressing reagents.

Similar successes have been made in other mines.

The Munphyong Smeltery and the Taedonggang Battery Factory have made successes in the production by finding out a number of ways to raise the production efficiency to the maximum in each process.
