中文摘要: 探索煅烧二氧化碲造液澄清速度的影响因素,试验结果表明 :煅烧温度是决定造液澄清速度的主要因素 ;相比 450℃煅烧 TeO2,350℃煅烧 TeO2 造液后,溶液的澄清速度显著提高,Cu、Bi、As 杂质更多的进入到造液渣中 ;添加 CaCl2 可以提高造液溶液的澄清速度 ;采用低碱造液工艺,添加絮凝剂 PAM、添加淀粉,提高澄清速度的效果不明显。
Abstract:Exploring the influencing factors of the clarification rate of calcined tellurium dioxide solution, the test results show that the calcination temperature is the main factor that determines the clarification rate of the solution; Compared to the 450 ° C calcination of TeO2 and the 350 ° C calcination of the TeO2 solution, the solution clarification speed is improved significantly. The impurities of Cu, Bi, As enter more into the slag; Adding CaCl2 can increase the clarification rate of the solution; The effect of using low-alkali slush process, adding flocculant PAM and starch to improve the clarification rate is not obvious.
