• Removal of Silica and Alumina as Impurities from LowGrade

    This study investigates the removal of silica and alumina as impurities from hematite based lowgrade iron ore containing 34.18 mass% iron, 31.10 mass% of silica and 7.65 mass% alumina. Wet highintensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process, 93.08% of iron was recovered with a grade of 53.22 mass% at an optimum magnetic density of 10,000

    Etymology. The word garnet comes from the 14th‑century Middle English word gernet, meaning ''dark red''.It is derived from the Latin granatus, from granum (''grain, seed''). This is possibly a reference to mela granatum or even pomum granatum (''pomegranate'', Punica granatum), a plant whose fruits contain abundant and vivid red seed covers (), which are similar in shape, size, and color to some
