摘要
在我国,含钒品位低于0.8%的石煤不但超过总量的60%,而且在高品位的矿山中也总夹杂着低品位的矿层或者矿带。为此,选取了贵州某地品位为0.60%的石煤为原料,采用硫酸+助浸剂R1+氧化剂R2体系进行了酸浸提钒试验研究。结果发现,该低品位石煤在一定条件下浸出率可达90%,并且在当前的市场条件下具有一定的经济价值。
In China,not only the reserves of flae vanadium coal stone ores with grade of less than 0.8% are over 60%, but it is always found in the high - grade mines also often extrain some low - grade ore,beds or ore belts. For this reason, an experimental research on extracting vanadium by acid leaching method was carried out. A stone coal from Guizhou province with grade of 0.60% vanadium was selected as raw material and the sulfuric acid ＋ auxiliary leaching agent R1 ＋ oxidant R2 system was adopted. The results indicated that the leaching rate can reach 90% under optimal conditions, and to a certain extent, it has certain economic value in current market quotation.
