Studies on Utilizations of Serpentine [] Chemical Studies on the Fertilizer of Ignited Serpentine

摘要

In order to investigate the availability of serpentines occurring in Korea as fertilizer, the dissolving rates of Magnesia and Silicate contents in 0.5N HCl solution after heat treatment of the serpentines, have been studied. It was found that calcination of the serpentines at 700?é for 30 min. was the best condition for utilization of serpentines as fertilizer. The weight decrease on calcining has also been discussed from the chemical point of view.
