Process Research on Vanadium Extraction from Stone Coal by High Temperature Curing and Column Leaching AITranslate
Abstract AITranslate
The extraction of vanadium from stone coal was carried out by the process of acid mixing pelleting,high temperature curing and column leaching.Also,the study discussed the leaching effect of vanadium from raw ore affected by process conditions such as the amount of sulfuric acid,the amount of water supplement for curing,the binder dosage,the curing temperature,the curing time,the particle size of the cured material and the spraying intensity.The results show that the leaching rate is 76.99%when the conditions of the process are as follows:The particle size of the raw ore is less than 12 mm;the water content of the raw ore is 10%;the amount of sulfuric acid is 20%;the binder dosage is 0.05%;the curing temperature is 135 C;the curing time is 10 h;the particle size of the cured material is less than 8 cm;the liquid-solid ratio of leaching section is 1.5:1;the spraying intensity is 15 L/(m2·h).After the leaching residue is washed four times(the liquid-solid ratio of washing section is 1.5:1),the leaching rate of vanadium can be increased to 87.48%,and the content of V2O5,in the tailings can be reduced to 0.11%.The research can provide important reference for the industrial production of the heap-leaching of vanadium ore.
