Special Issue "Molecule Structural Design of Non-Ferrous Ore Flotation
Dear Colleagues, We were approached by the open-access journal Minerals to serve as Guest Editor and Co-Editors for the Special Issue “Molecule Structural Design of Non-Ferrous Ore Flotation Collectors”. We invite contributions to this Special Issue on all the aspects of the molecule structural design and syntheses of flotation Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be increased in copper ores, so the appropriate depression of sphalerite floatability should be achieved to obtain saleable copper Minerals Free Full-Text Flotation of Copper Ores with High

Mineralogical Prediction on the Flotation Behavior of Copper
The hypothesis is that the flotation kinetics of blended copper-molybdenum ore in seawater can be estimated by the flotation kinetics of each copper and molybdenum mineral from each copper-molybdenum ore. Table 11 shows that the actual value of Rmax and k of blended copper-molybdenum ore is close enough to the This froth flotation method is used to treat quartz sulfide ores or gold-silver-bearing pyrite and pyrrhotite containing gold telluride, pyrrhotite, chalcopyrite and other sulfide minerals. The floatable gold telluride in the ores is first produced as a concentrate, and then roasted and cyanided to expose gold and silver ores in sulfides andFroth Flotation Method JXSC Machine

Bioleaching of copper ore flotation concentrates ScienceDirect
The results of the leaching of gold–copper concentrate are shown in Fig. 1. As can be seen the best results were obtained at 12% and 15% of solid. The surface area of gold-bearing flotation concentrate increased from 2.92 to 7.33 m 2 /g and 7.37 m 2 /g after 168 h (7 days) biooxidation. The effect of the ferrous iron concentration on the.Various technological schemes [9, 10] of copper ore and copper-zinc ore processing,technological schemes of direct selective flotation and variants of collectively selective schemes have been developed and introduced for refractory pyrite-pyrrhotite-copper-zinc ores of Tarnersky, New Shemursky, Podolsky, Uzelginsky, Safyanovskoye, Complex Processing of Refractory Pyrite Copper, Copper-Zinc and

The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore. At present nearly 2 billion tons of ore in the world are treated by the froth flotation process. According to rough statistics, about 90% of non-ferrous minerals are recovered by the flotation method, accounting forPorphyry-type deposits are the major sources of copper and molybdenum, and flotation has been adopted to recover them separately. The conventional reagents used for depressing copper minerals, such as NaHS, Na2S, and Nokes reagent, have the potential to emit toxic H2S gas when pulp pH was not properly controlled.
