Abstrakty

In this study, the Taguchi method was used to determine the optimum conditions for leaching of dolomite ore in hydrochloric acid solutions. The experimental parameters were leaching temperature, solid-to-liquid ratio, acid initial concentration, leaching time and stirring speed. The following optimum leaching parameter levels were found: temperature 50°C, solid-to-liquid ratio 2%, acid concentration 20 g/cm3 (2 mol/dm3), stirring speed 450 rpm, leaching time 5 min. Under the optimum process conditions, the dolomite ore leaching efficiency was about 83%.

Wykorzystano metodę Taguchi do określenia optymalnych warunków ługowania rudy dolomitowej w roztworach kwasu solnego. Badano takie parametry jak temperatura, stosunek fazy stałej do ciekłej, początkowe stężenie kwasu, czas ługowania i prędkość mieszania. Ustalono, że optymalnymi parametrami są: stosunek fazy stałej do ciekłej 2%, początkowe stężenie kwasu 20 g/cm3 (2 mol/dm3), prędkość mieszania 450 rpm, czas ługowania 5 min. W tych warunkach wyługowanie dolomitu było około 83%.
