Microwave-heated Alkali Activation,Water Dissolving and HCl Leaching of Used Firebrick from Glass Fiber Industry for Enrichment of Pt and Rh
玻纤工业废耐火砖中铂铑金属微波碱熔活化-水溶酸浸富集工艺

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...
