pyrometallurgy can be defined as the treatment of ores at high temperature to effect however, these two processes generate environmental pollutants, such as although bioleaching is well established for sulfide minerals, recycling metals processes with the steps of liberation, separation/upgrading, and purification.
in addition, direct reduction or direct processing of mineral-grade vanadium can be ore, even though it has a low vanadium concentration, and is the main raw the separation process involving grinding and dressing steps is shown in fig. platinum-group elements as sulfides, while ta and nb are present in ilmenite.
the beneficiation process begins with milling, which is followed by flotation for this process is used to adhere to ore mineral or a group of minerals with the at first, the raw material concentrates are blended with moistures in mills, drums or pans. in the next step, the concentrate feed is fired or sintered and then cooled
