Recovery of gallium and vanadium from gasification fly ash
Consistent with the mineralogy at Wolfram Camp, Ga is likely associated with bauxite and sphalerite (ZnS) (Font et al., 2007), with the Wolfram Camp W tailings possessing both Al minerals, e.gBauxite residue, the byproduct of alumina production, may potentially be a valuable source of strategically important metals, e.g. Gallium. Ga is considered critical element for the EU. To ensure adequate supply of Ga for the future, secondary sources such as bauxite residue should be exploited with efficient extraction methods. Therefore, in [PDF] Recovery of Gallium from Bauxite Residue Using Combined

The History, Challenges, and New Developments in the
The paper serves as a brief overview of the history and trends in the management and use of bauxite residue, outlining: the dimensions of the problem; the characteristics of bauxite residue; how methods of storage and disposal have developed over time and the implications for bauxite residue use; an example of a soil less free extract gallium and vanadium from the sludge than the main components such as iron, aluminum and titanium. Methods have been developed for the extraction of gallium and vanadium from bauxite sludge based on dissolution in mineral acids [5,8] or in alkaline solutions [7].

An evaluation of the general composition and critical raw material
On average the vanadium, gallium and scandium content measured in the bauxite residue samples were 510 ± 77.8, 107 ± 7.3 and 51.4 ± 5.4 mg kg −1, respectively. This shows promise for the potential reuse of bauxite residue as a secondary source for critical raw materials and also indicates that BRDAs may be potential mines for critical Introduction. Red mud is the solid waste product of Bayer process for the production of alumina from bauxite ores (Liu and Li, 2015). Annually, approximately 120 million tonnes of red mud is generated with an estimated global inventory of over 3 billion tonnes (Power et al., 2011).For possible metal recovery techniques from bauxite or red Gallium and vanadium extraction from red mud of Turkish

Bauxite waste management » AlSiCal
AlSiCal and Bauxite residue management. There are many projects and initiatives which focus on minimizing the waste through its utilization or/and producing alumina with zero-bauxite-residue methods, hence contributing to a greener and more sustainable metal industry throughout the entire supply chain. The AlSiCal project Bayer liquor is the biggest raw material resource for gallium production. Four kinds of methods have been developed to recover gallium from Bayer solutions, including fractional precipitation, electrochemical deposition, solvent extraction, and ion exchange. The fractional precipitation method is based on Al–Ga precipitation with CO 2 andRecovery of gallium from Bayer liquor: A review ScienceDirect

Abstract. In this study, recovery of vanadium and gallium from solids waste by-products (vanadium sludge and electrofilter dust of calcination plant) of Bayer process was investigated. AnResource figures are current as at 31 December 2016. Bauxite is a natural product of weathering and occurs as a white to grey to reddish orange-brown crust at or near the Earth's surface in regions that have, or have had in the past, high rainfall. Bauxite is generally hard, heterogeneous in appearance and can be nodular, layered or massive.Bauxite Geoscience Australia
