摘要:

为确定氯化铵焙烧水浸法处理低品位锰矿的最佳工艺,考察了焙烧温度、焙烧时间、氯化铵与锰矿的质量比等因素对锰浸出率的影响。在单因素条件实验基础上,以锰浸出率为响应值,采用Box-Behnken响应曲面分析法优化了反应条件。氯化焙烧水浸处理低品位锰矿最优条件:焙烧温度为460 ℃、焙烧时间为90 min、氯化铵与锰矿的质量比为1.42。响应面法建立的模型预测锰浸出率为94.71%,实验值为94.59%,两者偏差不大,方法可行。

Abstract:

:The best technical conditions were determined to obtain the best extraction process of manganese from low-grade rhodochrosite by chlorination roasting-water leaching process.The influence of calcination temperature,calcination time,mass ratio of ammonium chloride and rhodochrosite on manganese leaching rate was investigated.Taking manganese leaching rate as response value,the reaction conditions were optimized by Box-Behnken based on the results of single factor experiments.Results showed that the optimum conditions of the extraction of manganese from rhodochrosite were as follows:the calcination temperature 460 ℃,calcination time 90 min,the mass ratio of ammonium chloride to rhodochrosite was 1.42.The leaching rate of manganese 94.59% was obtained under these conditions,which accorded with the model predicted value of 94.71%.As the deviation between the two methods is small,and the method is feasible.

Key words: response surface methodology, rhodochrosite, roasting, water immersion
