The required carbon content needed in the reduction of vanadium tailings was determined theoretically based on the content of Fe 2 O 3 in slag. According to the preliminary test, the molar ratio of carbon to Fe 2 O 3 was determined to be 1.04. To achieve better iron recovery, Na 2 CO 3 was added as a flux with mass ratio of 4% out of total …Web

Vanadium tailings (VTs) are the tailings produced as the metal vanadium is extracted from stone coal through crushing, calcination, and leaching. VTs mainly encompass SiO 2 and a small amount of Al 2 O 3 [1–3]. The production of every 1 t of V 2 O 5 from stone coal would generate 150 t of VTs. Usually, VTs are treated by tailings dam …Web
