Leaching Process of Potassium Sulfate from Roasts of Potash Feldspar, Gypsum and Calcium Carbonate 钾长石-石膏-碳酸钙热分解烧成物中硫酸钾的浸取过程
The results of leaching experiments in ammonium carbonate system indicate that leaching rate is not more than 60%. 研究结果表明,碳铵体系下方铅矿精矿浸出率偏低,最高不超过60%。
Selective leaching of nickel, cobalt and copper from cobalt crusts was attained by using ammonium carbonate solution and sulfur dioxide gas as a reductant. 二氧化硫作还原剂,用碳酸铵溶液可实现从钴壳中选择性浸出镍、钴和铜。
Leaching characteristics of some highly sulfidic carbonate uranium ore deposit 某矿床高硫分碳酸盐铀矿石的浸出性能
Study on the reacting dynamics of leaching low-grade roasted molybdenite with sodium carbonate solution 碳酸钠溶液浸取低品位钼焙烧矿反应动力学研究
This may be due to preferential leaching of light carbon isotope ( 12C) out of carbonate sediments by hydrothermal fluids. 我们认为这是碳酸盐不饱和的热水溶液对碳酸盐沉积物中轻碳同位素(~(12)C)优先淋滤的结果。
Cobalt crusts were leached in an ammoniacal solution using sulfur dioxide gas as a reductant, and the effects of leaching time, leaching temperature and concentration of ammonium carbonate on the leaching of nickel, cobalt, copper, iron and manganese were investigated. 钴壳用二氧化硫气体作还原剂进行了氨浸,研究了浸出时间、浸出温度和碳酸铵浓度对镍、钴、铜、铁和锰浸出的影响。
