The study of magnetite iron ore separation in Qinghai Province

摘要

Magnetite ore from Qinghai Province West China was studied. Quartz, silicate and olivine are mostly associated with magnetite in native as inclusions, and have micro-fine disseminated structure. Coarse grinding is done for energy saving, and then magnetic separation is processed. In order to meet the industry requirements of concentrate, flotation is processed to improve the grade. A stage grinding and flotation processing is accomplished finally.
