| 摘 要： | 采用微波碱熔活化-水溶酸浸富集工艺处理玻纤工业废耐火砖料，使其中的铂铑金属在酸浸渣中得以富集. 通过微波加热碱熔与常规加热碱熔对比实验，考察了碱熔温度、保温时间、配碱量对碱熔过程的影响. 结果表明，微波辐照温度800℃、保温时间30 min、碱熔剂NaOH为样品质量的1.4倍时，碱熔反应进行彻底. 熟料经水溶后，在最优条件下酸浸，在盐酸浓度3 mol/L、浸出时间5 min、酸料比15 mL/g的条件下，料浆过滤性能良好，出渣率2.98%，铂铑金属可富集约33倍.

| Abstract: | The process of microwave alkali-activation,water dissolving and HCl leaching to beneficiate Pt and Rh from discarded firebrick of glass fibre industry was studied.Comparison tests of microwave alkali-activation and conventional alkali-activation for discarded firebrick were carried out to investigate the effects of activation temperature,heating preservation time and additive dosage on alkali-activation reaction.The results show that the reaction is completed thoroughly when the test sample is alkali-activa... |
