study from bauxite ore deposit

Study of Minor Bauxite Deposits, Madhya Pradesh ...

2021-1-25  Indian bauxite deposits are mainly of lateritic origin. They have been grouped into five major bauxite districts based on similar geological and geomorphological features. Apart from major bauxite deposits of Eastern Ghat District (Orissa and Andhra Pradesh), minor pocket type deposits, particularly Satna, Rewa, Katni, Anuppur districts and adjoining areas belonging to Central Indian District have their own importance. Four representative deposits of these areas namely Naru (Satna), Tikar (Rewa), Padwar (Katni) and Chachandee (Anuppur) were studied with reference to their mineralogy, reserves and grade, mining and its impact on environment and techno-economic evaluation. Each of these deposits has reserves of less than 10 million tonnes mixed with three grades of ore namely metallurgical, refractory and cement. There are several other similar occurrences of bauxite in these areas. Mining methods in these deposits is erratic and selective. Associated clay and ochre mining is a characteristic feature of these deposits.

Bauxite Deposits - an overview ScienceDirect Topics

Bauxite, a globally abundant ore of aluminum, is a viable, effective, and low-cost fluoride adsorbent alternative to AA. Raw bauxite ore is comprised of a primary aluminum oxide mineral known as gibbsite [Al(OH) 3 ] [25–27] and its material cost ($30/tonne) [28] is 50 × lower than the heavily processed and purified end product, AA ($1500/tonne) [29] .
