Study of the Effect of Fluxing Ability of Flux Ores on Minimizing of Copper Losses with Slags during Copper Concentrate Smelting

The article describes the effect of fluxing ability (FA) ores used as a flux on slag formation and copper losses. In Kazakhstan, at Balkhash smelting plant (BCSP), currently fluxes have very low SiO2 content—about 62%—whereas Al2O3 content is 12%. Its was estimated, it shown that silica an exceedingly FA. Only half participate in formation. To obtain slags with magnetite concentration, considerable surplus must be added, which will result sharp reduction its melt temperature, increased output, therefore structure studied by means scanning electron microscopy probe microanalysis (EPMA). determine one primary causes ores’ FA, necessary to use microstructural pattern experimental samples.
