Tambayoyi Masu Yawan Tana Yi Game Da Raba Nauyi Ta Hanyar Jawo Jiki Da Zabi Na Frof Flotation
Q1: Shin rarrabuwar nauyi ta fi araha fiye da fasa?
A: Yes. Gravity separation typically has 2-4× lower capital and operating costs than flotation. No reagents, simpler equipment, and less energy consumption.
