BOX-BEHNKEN DENEY TASARIMI İLE MİKRODALGA ENERJİLİ ISITMANIN YÜKSEK SÜLFÜRLÜ ALTIN FLOTASYON KONSANTRESİNE ETKİLERİ: OPTİMİZASYON VE MODELLEME

In this study, the effects of microwave heating on sulphidic refractory gold concentrate were investigated. When microwave energy is applied, the power (Watt), time (minute) and mass (g) independent variables, which are the effective parameters of the heating or roasting process, are designed as 15 experiments over 3 variable Box-Behnken and model equations are developed for dependent variable. Gold ore used in the optimization studies is the flotation concentrate which has been reached to 4 ppm Au and 21% sulphur content in our previous Denver flotation studies obtained from the western part of Turkey, Aegean region. Minitab program was used to analyse optimization values, it was found that the transfer of 680 W microwave energy on the sample in 3 g amount was sufficient during 30 minutes.
