Fray Symposium - Effects Of Mineralogical Characteristics Of Concentrate Blends On Flash Smelting Phenomena. Six types of concentrates with values of S/Cu from 0.957 to 1.424 were used. Different binary blends were tested as well of blend of different sizes fractions from two types of concentrates (ie the fine fraction of concentrate a, with the coarse fraction of concentrate b). Mineralogical analyses of synthetic phases obtained by quenching were performed using QEMSCAN®. The results were interpretated by using the group combustion theory.

    Abstract:

    The study of fundamentals transformations of different copper concentrates blends under flash combustion were studied at laboratory scale using a "drop tube" set up. The effect of particle sizes and mineralogical composition of copper concentrates were evaluated in order to analyze those effects in the quality of the combustion where the ignition temperature, the sulfur removal and the Fe3O4 formation were used as quantifiable parameters for the characterization.Six types of concentrates with values of S/Cu from 0.957 to 1.424 were used. Different binary blends were tested as well of blend of different sizes fractions from two types of concentrates (ie the fine fraction of concentrate a, with the coarse fraction of concentrate b). Mineralogical analyses of synthetic phases obtained by quenching were performed using QEMSCAN®. The results were interpretated by using the group combustion theory.
