School... minerals in the electro-generating leaching(EGL) and the bio-electro-generating leaching(BEGL), respectively. The results showed that the dissolution rates for Cu2+ and Fe2+ in BEGL were almost 2 times......
of secondary reaction, dry sintering process without alkali [8,9]. The main aluminum phase of lime sinter process is 12CaO·7Al2O3 whose alumina leaching property is excellent [10]. However, it also owns a lot... as leaching container which was connected with the circulating cooling water. The experiments were performed under the following conditions: carbon alkali concentration (NC) was 80 g/L, caustic concentration......
