    However, the iron ore from Kashenyi hill has lower iron content (about 6l% Fe) and higher gangue content (5% SiO 2 and 6% Al 2 O 3) at low concentration of the deleterious elements (0.02% P and 0.003% S). According to commercial standards for crude iron ores, this ore can be defined as medium-grade ore.
