%X The effects of temperature, time, and agitation speed on the acidic precipitation of ammonium polyvanadate from the plant of vanadate-leaching solution were investigated on a laboratory scale. The results show that for the vanadate-leaching solution containing 30 g/L of vanadium, keeping pH about 2.2 at the beginning of precipitation reaction, temperature at about 95oC, agitation speed at 300 r/min, and reaction time being 120 min, could result in the following results: precipitation rate is more than 99%, H2O content in red cake is less than 20%, Na content in dried red cake is between 0.70% and 1.08%, and sulphur content in dried red cake is between 0.78% and 1.02%.
