Process optimization on the extraction of rubidium from ,

The rubidium extraction yields for CaCl 2 and NaCl were 9398% and 4479%, respectively, which were attributed to the higher chlorine content in CaCl 2 The addition of CaCO 3 had no effect on the rubidium extraction, which might be that the produced carbon dioxide from the decomposition of CaCO 3 could not react with biotite...

Effectiveness acidic pre-cleaning for copper-gold ore

The copper extractions were 60% and 83%, respectively The lower extraction for FS003-78, relative to the sample FS004-87, might be related to the following reasons: greater biotite content (103% versus 35%), in which copper is less soluble in cyanide, and also the copper associated with iron hydroxides (Osseo-Asareet al,1984)...
