[交流] 汉译英,一句话

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.

帅哥,还有句麻烦你了,翻译完再送30BB

用过0.074mm标准筛的矿为原料,最适反应条件为:酸解反应温度为750℃,反应时间为5d,磷酸(85.56%)用量为56ml(/1g磷钾矿);离子交换反应温度为930℃,反应时间为3h,此时磷和钾的溶出率都可以达到80%以上。探讨了各阶段的反应机理,并对主要反应进行了热力学分析

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.
