Research intensified to develop and use resources in an effective way

July 4, 2023

The resources science faculty of Kim Il Sung University is intensifying research into developing and using resources of the country in an effective way.

Its greatest success is that it established a technique of exploration and intake of underground ultra-brine resources. A research group of the faculty conducted research on the resources previously unknown in the geological circle of the country, thus putting another item in the list of its natural resources.

The group established and introduced in practice the criterion for and method and technique of prospecting underground ultra-brine resources for the first time at home to find out a promising deposit of ultra-brine under the west coastal area of Korea and established a method of using the underground ultra-brine to produce salt. This enabled different saltworks to drastically reduce the area of salt fields and remarkably increase the frequency of annual salt production and the output per hectare so as to boost salt production every year.    

Key developer Kim Ryong Hung, candidate academician, professor, PhD and head of the marine resources laboratory, was nominated as one of top national scientists and technicians in 2022 and awarded the February 16 Science and Technology Prize.

Anticorrosive paint developed by the faculty is also in wide use in different sectors. It was made from wad abundant at home.

“Anticorrosive paint is very important in increasing the lifespan of steel structures or ironware. It is made by adding solvent and anticorrosive functional fillers to the medium forming paints membrane and what is important here is to decrease the cost of the fillers preventing iron from oxidizing and enhance the efficiency of the fillers,” said Kim Kwang Min, vice-dean for academic affairs.

Another research group of the faculty clarified how wad prevents corrosion and solved sci-tech problems arising in making the paint capable of preventing corrosion to the maximum, thus succeeding in developing a highly efficient anticorrosive paint costing quite less. 

The faculty now works to use phosphorite available at home to produce phosphorus fertilizer badly needed for increasing grain crop yield.

It already carried out a field geological survey and prospecting of an area which is expected to have the largest deposit of phosphorite and analysed their phosphorus content to confirm its value as fertilizer and drew up the plans for relevant mining and development.
