When leaching at pH < 0.5, CaV 2 O 7 dissolved in the sulfuric acid solution as VO 2 2+.The leaching behavior and kinetics of the calcification roasted converter slag in sulfuric acid (1–27%) have been investigated [].However, CaV 2 O 7 dissolved in the sulfuric acid solution as V 2 O 7 4− when leaching at pH 2.5, The leaching of calcification roasted converter slag in …
We compared chemical and microbial leaching for multi-metal extraction from printed circuit boards (PCBs) and tantalum capacitor scrap. A mixed consortium of acidophiles and heterotrophic fungal strains were used in the experiments and compared to chemical leaching using specific acids (sulfuric, citric and oxalic acids). Under optimum conditions, …

ferromanganese slag was pre-mixed with 100 ml of water. The milled ferromanganese slag slurry was digested in 100 ml of concentrated sulphuric acid. The quantities of the slag and sulphuric acid were determined by calculating their stoichiometric quantities, and also according to Lindblad and Dufresne (1975).
The shaking tables (gravimetric tables, concentrating table, shaker tables, gold shaking table) are the most widely used and efficient gravity separation equipment for fine ore separation. It is widely used in the beneficiation of rare metals and precious metal ores, such as gold, copper, tin, tantalum, niobium, iron, manganese, chromium, etc.
