Difference Between Bauxite and Iron Ore Definition Bauxite is also known as aluminum ore and contains aluminum bearing minerals Iron ore is a type of rock from which we can extract iron Iron ore is a type of rock from which we can extract iron The main difference between bauxite and iron ore is that bauxite is a source of aluminum whereas iron ore is a source of iron -composition of alumina in bauxite ore-,Bauxite ore crusher priceBauxite is the main source of the rare metal gallium During the processing of bauxite to alumina in the Bayer process gallium accumulates in the sodium hydroxide liquor From this it can be extracted by a variety of methods The most recent is the use of ion-exchange resin Achievable extraction efficiencies critically depend on the original concentration in the feed bauxite …… Get More
