摘要： This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.

摘要： A fine particle producing process introduces a material for producing fine particles into a thermal plasma flame to make a vapor-phase mixture and quenches the vapor-phase mixture to form the fine particles. In the process, the material for producing the fine particles is dispersed or dissolved in a dispersion medium or solvent, preferably containing a combustible material to prepare a dispersion such as a slurry, a colloidal solution or a dissolution solution, the dispersion is made into a form of droplets, or the material for producing the fine particles is dispersed with a carrier gas and a combustible material and the dispersion in a droplet form or the dispersed material is introduced into the thermal plasma flame. In the fine particle producing process and apparatus, a gas of an amount sufficient to quench the vapor-phase mixture is supplied toward a tail of the thermal plasma flame. In the process and apparatus, primary fine particles are introduced into a cyclone to be subjected to cooling and classification and secondary fine particles having a particle size of 100 nm or less which are left upon removal of coarse particles are recovered.
