- Simultaneous acid leach of ZnS concertrata and Pyrolusite ore is used to obtain Zn and Mn Solution,leach rates of Zn and Mn are up to 97% and 95%.
- The vanadium phase and valence state of stone-coal with low carbon in Guizhou province were analyzed by electron probe,and a pressure acid leach experiment was carried out.
- The acid leaching kinetics of serpentine was researched.
- Thermodynamic analysis results show that tellurium can be leached by sulfuric acid leaching method from lead-rich tellurium slag.
- It was shown that during the sorption, alcoholic leached soy protein concentrate(SPC)exhibited smaller monolayer sorption value than aqueous acidic leached SPC, without swelling observed.
