Initial investigations have provided a first insight into the geology and conditions of lateritic bauxite deposits formation in the WZD area Jin et al 2009 Liu 2007 Wu et al 2006 Wu et al 2008 Liu et al 2010a Yin 2009 However the detailed ore forming process is still ambiguous and the source rock of the WZD bauxite deposits has long been a matter of debate
The genesis of bauxite is closely related to carbonate or mafic basement and controlled by lithofacies paleogeography paleoclimate palaeogeomorphology and other factors bauxite ore
In this study we present the main findings from microstructural and mineralogical studies and their implications for the genesis of bauxite/laterite in Mainpat plateau Megascopic studies showed reddish laterite to off white bauxite Strong hydrolytic action formed small oolites and large pisolites with sizes of 1 2 cm in diameter Pisolites and oolites were
Compared to the bauxite ore the genesis of the entire aluminous bearing strata has received less attention In this study we conducted geological mineralogical and geochemical analyses on core samples from the aluminous bearing strata located in Xingxian area situated within the northern NCC aiming to elucidate the genetic process of
The document discusses bauxite including its mineral composition locations of deposits and uses It notes that bauxite is the primary ore for aluminum production India has significant bauxite reserves and is the 5th largest producer globally • Bauxite deposits are classified into 3 types based on their genesis • LATERITIC BAUXITE

The occurrence of deferrification process and multicolored bauxite ore ranging from white gray to brown red is evidence of biological and herbal activities that lead to reducing conditions
Karst bauxite is a major source of aluminum and contains high concentrations of trace elements such as Li Ga Sc and rare earth elements REEs It is regarded as a potential non conventional REE source due to the increasing demand for REEs This study provides new mineralogical and geochemical evidence of a Lindai bauxite deposit in central Guizhou
Major and REE geochemistry and multi fractal analysis of two types of bauxite primary bauxite and accumulated bauxite ores were studied in Pingguo bauxite orefield in western Guangxi China The results of geochemical data show that the accumulated bauxite has a feature of high Al2O3 whereas relative low Fe2O3 and SiO2 contents compared to the
The mineralogy and texture of ore deposits are important for the aluminum extraction industry because they comprise the main factors that determine whether a metallurgical process will succeed or fail which renders a deposit economic or uneconomic Boni et al 2013 Therefore the evaluation of bauxite ore from petrography and mineralogy is important to
The formation comprises a stratum of bauxite hosting Shanxi style iron ore in its lower section a bauxite G layer in the middle section and gray and dark gray mudstone as well as carbonaceous mudstone in the upper section 21 Various types of formations such as dense massive pea oolitic porous or earthy semi earthly and clastic
Bauxite is a term currently used for weathering products or sedimentary rocks rich in alumina but low in alkalis alkaline earths and silica Gow and Lozej 1993 Bauxites containing 3 5% combined silica less than 20% Fe 2 O 3 and more than 45 50% Al 2 O 3 are considered as bauxite ore Valeton 1972; Gow and Lozej 1993 the main raw material of aluminum Al

1 Introduction Bauxites are residual aluminum deposits derived from lateritic weathering of pre existing alumosilicate rocks under tropical and/or subtropical climatic conditions characterized by annual precipitation rates of 1 200 mm and annual temperatures above 22 °C Bárdossy 1982 Bauxite is the main aluminum ore and also represents an important source
The bauxite genesis is recorded in the bauxite geochemical composition as a unique signature of tectonostratigraphic evolution of the different parts of the Croatian Karst including for example
This pattern of critical metal enrichment reflects a three stage genesis of bauxite linked to in situ weathering and bauxitization which provide insights into the weathering history of other
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
Rovinj 1 karst bauxite deposit is one of the few deposits with ongoing bauxite exploitation which is not used in aluminium production but as an additive in cement industry and a secondary ore in mineral wool production due to its high silica deposit formed between the early Kimmeridgian and late Tithonian and it is the largest bauxite deposit among
All these processes can make it more difficult to understand the original controls of bauxite ore formation and to carry out effective regional exploration for hidden bauxite deposits In the present work we have utilized this new integrated approach to study the fundamental controls on the genesis of the karst type bauxite deposits in
