Gravel can be bauxite, it depends on how much available aluminium it has in it. Generally speaking bauxite is found between 1 to 5 metres in depth and is shown in the image adjacent.Bauxite ore ranges in character from solid hard cap or duricrust,Bauxite Extraction Process — WORLDVEST PARTNERS,Bauxite Mining Processing. Bauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum. Bauxite is one of the most abundant elements on earth and contains nearly 25-30% of alumina. Its typically found near the equator in tropical and subtropical regions, in the form of horizontal layers beneath a few meters of overburden,Mining and Refining – Process,Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of,

Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240,Extracting metals using electrolysis - What are,,It is expensive, largely because of the amount of electricity required in the extraction process. Aluminium ore is called bauxite.
