Vanadium is the 22nd most abundant element in the continental crust and it accounts for approximately 0.014% of it (Rudnick and Gao Citation 2003); however, concentrations of at least an order of …
The influence of roasting on the leaching rate and valence of vanadium was evaluated during vanadium extraction from stone coal. Vanadium in stone coal is hard to be leached and the leaching rate is less than 10% when the raw ore is leached by 4 mol/L H 2 SO 4 at 90°C for 2 h. After the sample is roasted at 900°C for 2 h, the leaching rate …
The relation of the optimum amount of additive with the composition of silica based vanadium ore roasted with calcium compounds for was studied. A calculating formula for the roasting load was proposed. The roasting mechanism was explored and it is believed that vanadium exists in the calcifying roasted ore mainly in form of calcium silicon …
