The boundary is determined by the cut off given for the bauxite ore. It also may occur that that the bauxite ore forms lenses: for example, in Kolhapur district (West Coast, India) there are lenses of sub grade laterite of 1–2 km long 300–400 m wide and 2–3 m thick. This type of bauxite ore is quasi floating inside the laterite capping.

The studies on bauxites in central Yunnan province suggested that the bauxite has an autochthonous origin and derived source materials from underlying carbonates based on the REE patterns and immobile elements correlation analyses (Wen et al., 2020).Based on the trace element geochemistry, it's also proposed that the bauxite was deposited under oxidizing to …

The raw bauxite ore undergoes coarse and fine crushing to a certain particle size for subsequent processing. The ore is dried to remove moisture and improve beneficiation efficiency. 2.Gravity beneficiation： Gravity beneficiation is a process that utilizes the density differences of different minerals in ore to achieve separation.
