| 用反向浮选法预处理矿，使得铁和铝的品位得到一定程度提高；建立矿与硫酸共浸反应体系，将低温硫酸酸解反应与中温离子交换反应分开进行，考察了影响该体系钾溶出率的各种因素。 |

这样子：） The mineral was preprocessed by means of backward floatation process to get a higher grade of iron and aluminium;A mineral-sulphuric acid co-impregnation reaction system was built to seperate the low tempreture acid decomposition reaction of sulphuric acid and the middle tempreture ion exchange reaction; and influence factors like potassium apparentdissolution rate were also investigated. |

呵呵，这样子 For the 0.074mm standard sieve processed mineral, the best reaction conditions are considered to be 5d of acid decomposition reaction at 750℃, with a 56ml(/g kosnarite) 85.56% phosphoric acid amount and 3h of ion exchange reaction at 930℃. Both the phosphorus and potassium apparentdissolution rate can get above 80%. The reaction mechanism of every step is discussed and thermodynamic analysis is carried out for the primary reactions. |
