In the second half of the 19th century, the discovery of the spectral analysis method and the publication of the periodic table, coupled with the progress of the electrochemical separation process of rare earth elements, further promoted the discovery of new rare earth elements. In 1879, the Swedish-----
Sulfide ore biooxidation is under the action of autotrophic bacteria (e.g. bite Thiobacillus, Thiobacillus iron oxide), and the ore pre-treatment, the gold oxide and dissociated out, and then using a conventional cyanidation (or other methods) reacting Gold recycling. For pyrite, the resulting rea-----

The main chemical reactions in the leaching process of uranium , gold (and copper , silver ) ores occur in aqueous solution. These reactions may be related to the potential of the system and the pH of the solution, respectively, so the general formula is as follows: According to the theory of chem-----
Spiral chute is a relatively new type of gravity separation equipment, in recent years for sorting disseminated weakly magnetic iron ore and achieved good results. Its main features are: simple structure, low cost; high space utilization, small floor space; no moving parts, no power, low energy con-----
