introduction of bauxite ore

Introduction 3 widely both between ore beds and within a single deposit the different forms of bauxite are often categorized based on geological age and origin or chemical and mineral composition 6 The aluminum in bauxite occurs as hy-droxides classified as boehmite gibbsite or diaspore Gibbsite exhibits the Bauxite is an aluminium ore that forms just from the weathering of rocks Weathering is what happens when rocks are left out in the rain and comes in three forms physical chemical and biological Physical weathering is when bits of rock are attacked by wind or water or sometimes just gravity during rock falls
