Germany, part of Springer Nature 2019 Abstract: Bauxite residue disposal areas (BRDAs) are physically degraded and hostile to plant growth. Nevertheless, natural plant colonization was observed......
Optimization of selective copper extraction from chalcopyrite concentrate in presence of ammonium persulfate and ammonium hydroxideMehmet Deniz TuranDepartment of Metallurgical and Materials Engineering,F?rat University摘 要:The dissolution of copper and iron from chalcopyrite concentrate in the presence of ammonium persulfate(APS) and ammonium hydroxide......
Synthesis of ultrafine copper particles by complex-reduction-extraction method YANG Jian-guang(杨建广), YANG Sheng-hai(杨声海), TANG Chao-bo(唐朝波), HE Jing(何 静),TANG Mo-tang(唐谟堂) School... copper particles with satisfied anti-oxidation property was described. The resultant particles were characterized by X-ray diffractometry and scanning electron microscopy. The results show that well......
Thermodynamic equilibrium calculation on preparation of copper oxalate precursor powder FAN You-qi(樊友奇), ZHANG Chuan-fu(张传福), ZHAN Jing(湛 菁), WU Jian-hui(邬建辉) School of Metallurgical Science... were drawn. The results show that when pH is below 5.0, copper ion reacts with directly and the morphology of copper precursor powder is of pie-shape; when pH is above 5.0, copper ion......
