Selective flotation of scheelite from calcite using
#0183;#32;Microflotation tests were conducted in a XFGC flotation machine at 1800 rpm with a 40 mL cell. Mineral pulp was prepared by adding 2 g single mineral ( g scheelite and g calcite for mixed binary minerals) into the cell with distilled water. Pulp pH was adjusted by HCl or NaOH.
