the ferromanganese alloy. Attempts have been made to remove phosphorus from manganese ores [1]. The majority of manganese ore deposits in central India have relatively high (> 0.3%) phosphorus levels. Since phosphorus is intimately associated with manganese [1], physical beneficiation is unsuitable and chemical beneficiation is necessary.
