【摘要】：對(duì)貴州銅仁萬山地區(qū)含鉀頁巖焙燒提鉀工藝中的酸浸條件進(jìn)行了研究。前期研究中已確定了燒結(jié)條件,在本酸浸試驗(yàn)中,通過對(duì)酸的種類、酸的濃度、酸浸時(shí)間、酸浸溫度以及液固比等5個(gè)因素的研究,得到最佳的酸浸條件為:硫酸濃度9mol/L,液固比15∶1,酸浸溫度60℃,酸浸時(shí)間60min,此條件下鉀的溶出率為73.06%。此工藝流程簡單,而且降低了能耗,對(duì)含鉀頁巖的浸出及后續(xù)有效鉀的利用研究有一定指導(dǎo)作用。
[Abstract]:The acid leaching conditions of potassium-bearing shale roasting process in Wanshan area of Tongren Guizhou Province were studied. The sintering conditions have been determined in the previous study. In the acid leaching test, five factors, such as acid type, acid concentration, acid leaching time, acid leaching temperature and liquid-solid ratio, were studied. The optimum acid leaching conditions were as follows: sulfuric acid concentration 9 mol / L, liquid-solid ratio 15: 1, acid leaching temperature 60 鈩，
