The choice of high gradient magnetic separation processes for removal of Fe2O3 carriers from quartz raw material

“…Flotation concentration is preceded by washing and classification since clay component has to be removed as it negatively influences flotation selectivity of quartz from feldspar and mica (Banza et al 2006), published the results of improvement of processing quartz sand Hohenbocka (Germany) washing process, atrition and classification. Magnetic separation is used when quartz raw material, apart from other impurities, contains total iron carriers -Fe 2 O 3 which are magnetically susceptible (Sekulic et al 2002;Ignjatovic et al 1997;Sekulic et al 2016). The authors have studied literature in the field of magnetic separation, where many researches published their results concerning the raw material that can be treated by this process and the conditions under which it has to be undertaken (Bhatti et al 2008;Ibrahim et al 2002: Porat et al 2006Augusto et al 1999;Prakash et al 1999, Das et al 1991.…”
