Pengaruh Konsentrasi Larutan H2SO4 terhadap MgO, Kecepatan Pengadukan, dan Lama Pelarutan H2SO4 pada Pembuatan pupuk Kiserit dari Serpentin Asal gunung Badak Jampang Kulon Sukabumi

Abstract

The role of industrial minerals in urban and rural development is significant enough, such as agriculture areas which need zeolite and calotte etc. One of the industrial minerals which can be use dasfertilizerfor agriculture usage is kieseritefertilizer which is made from serpentiniterock. Serpentiniterock contents MgO which is potential for making kieseritefertilizer. Some variables of this research are grain sizes, heating temperature and time, and H&O4 concentration. This research pointed out the effects of H2SO4 concentration on MgOd Hlution. The findings of this research were the optimum grain size of 140 mesh, heating temperature of 600 C for 1 hour 45 minutes, and H2SO4 concentration of 5M.
