中文摘要: 采用制粒焙烧、碱浸、离子交换、煅烧工艺从某石煤钒矿选矿富集所产钒精矿中提钒。结果表明,V2O5焙烧收率99.50%,浸出率84.49%,净化收率98.15%,树脂吸附—解吸收率99.69%,沉钒—煅烧收率98.85%,全流程总收率81.31%,中间试验指标稳定可靠。所产五氧化二钒产品达到GB3283-87 V2O598牌号标准,副产品白炭黑SiO2含量可达96%以上。
Abstract:The pilot-scale experiment to recover V2O5 from stone coal vanadium concentrate was performed with processes including granulation-roasting, alkali leaching, ion exchange, and decomposition. The results show that roasting rate of V2O5 is 99.50%, leaching rate is 84.49%, purification rate is 98.15%, ion exchange rate is 99.69%, decomposition rate is 98.85%, and overall recovery rate of V2O5 is 81.31%. The technological parameters of this pilot-scale experiment are stable and reliable. The products reach the standard of GB3283-87 V2O598, and SiO2 content in white carbon black is 96% above.
