  • Selective flotation of siderite and quartz from a

    31 Single mineral flotation tests Single mineral flotation tests were carried out to investigate the pH effect on the floatability of hematite, magnetite, siderite and quartz, respectively The tests were conducted under the conditions of 200 mg/dm3 αEDALA and 18ºC of flotation temperature The pulp pH was varied within the range from 6 to 12 As per Fig 2, αEDALA presented 01/04/2016  The flotation results show that interactions between siderite and quartz are the main reasons that siderite significantly influences the floatability The interactions are attributed to dissolved siderite species and fine siderite particles The interaction due to the dissolved species is, however, dominantEffect and mechanism of siderite on reverse flotation of siderite concentrates theoretically is 48% Fe, together with Mn, Ca and Mg, because they are in the crystal structure of the mineral This fact makes beneficiation of siderite ores very difficult task Iron content ratio to manganese in siderite is close to SIDERITE ORE PHYSICAL SEPARATION AND REVERSE FLOTATION
