During the oxidation of low-grade molybdenum concentrate, metallic sulfide ores were oxidized to metallic oxides and SO2. Possible reactions are as follows: MoS2+3.5O2(g)=MoO3+2SO2(g) ...- rhenium sulfide concentrate as it is considerably more complex than that of standard-molybdenum concentrate due to, for example, the multiple components and impurities and the low-grade of molybdenum......

: complex copper oxide ores; occurrence state; temperature; leaching behavior; copper minerals 1 Introduction With the continuous depletion of high-grade copper sulfide ores, there is a need to win metals from the abundant complex copper oxide ores [1-3]. These ores have the characteristics of low copper grade, high oxidation rate, high combined rate, fine distribution granularity as well as extremely......
and sphalerite is relatively low above pH 5. When pH is more than 5, the fraction of adsorbed cells on pyrite is about 90%, and that on other sulfide minerals is less than 20%. The adsorption of Mycobacterium... decreases rapidly as pH is higher than 3.0, and then remains low under pH 5-11. Fig.4 shows the adsorption of Bacillus mucilayinosus cells on three sulfide minerals. It can be seen that the adsorption......
