摘要/Abstract

摘要：以8-羟基喹啉、磺原酸钾、十六烷基三甲基苄基溴化铵、磷酸三丁酯和柠檬酸为浸取添加剂，考察了添加剂用量、浸取时间、浸取温度和酸矿比等对铬离子浸出率的影响.实验结果表明：用0.8%磺原酸钾做添加剂，在固液比为1∶4（g/mL），酸矿比为0.3∶1(mL/g)，浸取温度为60 ℃下浸取90 min，Cr6+离子浸出率为38.11％，是加热浸取法的1.5倍.

关键词： 添加剂, 锰渣, 铬离子, 加热浸取

Abstract: Influence of additive dosage,leaching time and temperature,acid/ore ratio on Chromium ion leaching rate was investigated with 8-hydroxquinoline,potassium ethyl xanthate,hexadecyltrimethyl ammonium bromide,tributyl phosphate and lemon acid as additive.The results showed that leaching rate of Cr6+ reaches 38.11% when addition 0.8% potassium ethyl xanthate in temperature is 60 ℃,acid/ore ratio is 0.3∶1,liquid/solid ratio is　1∶4,and leaching time is 90　min;the leaching rate is 1.5 times of that obtained by heating leaching.

Key words: additive, manganese residue, chromium ion, heating leaching
