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.
Influence of additive dosage, leaching time and temperature, acid/ore ratio on Chromium ion leaching rate was investigated with 8-hydroxquinoline, potassium ethyl xanthate, hexadecyhrimethyl ammonium bromide, tributyl phosphate and lemon acid as additive. The results showed that leaching rate of C^6＋ 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.
