Scientific researches intensified for lower production costs and quality improvement
The Mathematics Research Institute and the Experimental Equipment and Process Automation Institute of the Hamhung Branch are putting efforts into carrying out the research tasks conducive to revitalized production and quality improvement in the fields of metallurgical and chemical industries.
The Ore Dressing Engineering Research Institute promoted the remodelling of the reagent supply system of the flotation process at the Phungnyon Mine, making it possible to maintain the grade of apatite concentrate on a high level while reducing the amount of reagent consumption.
Officials and researchers of the Building Materials Institute also established a new technology of producing heat insulating materials with less cement by reusing slag which was once considered to be useless.
