Stone coal is a kind of combustiblewith the characteristics of low-carbon, low-calorific, high-ash, and high-sulfur [1, 2]. The constituents of stone coal are complex associated with polymetallic composition [3, 4]. Thus, stone coal is an important resource of vanadium (V) [2]. More than 87wt.% of the domestic reserve of V came from stone coal

Stone coal is an important vanadium-bearing resource in China. The gross reserve of vanadium in terms of V 2 O 5 in stone coal accounts for more than 87% of the domestic reserve of vanadium [ 2 ].
The recovery of vanadium from a typical low-grade refractory stone coal was investigated using a pyro-hydrometallurgical process specifically including blank roasting, acid leaching, solvent extraction, and chemical precipitation. The appropriate role of parameters in each process was analyzed in detail. Roasting temperature and …
A novel technology, Two-Stage Roasting (TSR) process, was presented to promote the efficiency of vanadium leaching from stone coal. At the optimal condition of …
A new process of extracting vanadium from the stone coal vanadium ore in Fangshankou, Dunhuang area of Gansu Province, China was introduced. Various leaching experiments were carried out, and the results show that the vanadium ore in Fangshankou is difficult to process due to its high consumption of acid and the high leaching rate of …
Si was the most abundant element detected in stone coal (32.56%), while Al was the highest among metal (3.37%), followed by Fe (2.95%). Vanadium accounted for 0.23%, indicating that the stone coal used in this study was a typical low-grade-vanadium-containing stone coal ore.
