Review on High Phosphorous in Iron Ore: Problem and …
theless, iron ore with an Fe content of less than 25% can be explored whenever the ore deposit is huge and can be ben-eciated and transported cheaply. Classication of iron ore is based on the phosphorous content in it: low phosphorous iron ore (P < 0.07%), medium phosphorous iron ore ( = P 0.07–0.17%), and high phosphorous content (P > 0.10% ...

Biobeneficiation of bauxite ore through bacterial desilication
ABSTRACT Bauxite is an important mineral ore that is widely used in aluminum industry for metallurgical and refractory purposes. However bauxite contains silica as an impurity which degrades its quality. Silica forms complex with the caustic used during the processing of ore thereby forming precipitates. This leads to unnecessary wastage of caustic that contributes to …
