Pre-concentration of vanadium from stone coal by gravity ...

2013-6-10  In the gravity separation stage, 28.9% of the feed ore were rejected as final tailings, while the V 2 O 5 loss was 9.7%. The pre-concentration of vanadium from stone coal can improve the V 2 O 5 grade and decrease the content of high acid consuming minerals. The benefits of the pre-concentration process in terms of cost savings and solving ...

Pre-Concentration of Vanadium from Stone Coal by

Due to the low grade of V2O5 in stone coal, the existing vanadium extraction technologies face challenges in terms of large handling capacity, high acid consumption and production cost. The pre-concentration of vanadium from stone coal before the extraction process is an effective method to reduce cost. In this study, detailed mineral characterization of stone coal was investigated.
