Bauxite mining and economic growth in Guinea over the
Our results reveal that bauxite production has a positive impact on economic performance in Guinea. More precisely, the results indicate that, overall, one-third of the world’s known bauxite reserves (IFC, 2020). Gold made up 34 percent of mining production in 2019. Guinea is also the 16th-largest exporter and the IMF Country Report No. 21/147 GUINEA

Bauxite 101 The Bauxite Index
Bauxite Reserves The top 5 countries, Guinea, Australia, Brazil, Vietnam and Jamaica, hold over 70% of the world’s documented bauxite reserves. Bauxite resources are estimated to be 55 billion to 75 billion tons, in Fig. 1 (a) shows that Guinea was abundant in bauxite reserves, which were distributed in Kindia, Boke, Boffa, Fria, and Telimele. A single ore layer characterizes Guinea's bauxite, which was 3–9 m thick, usually found in open, gently undulating uplands, and was covered by mostly shrub-like vegetation [30].

Leaching Behavior of Lithium-Rich Beneficiation Tailings in Caustic
This paper systematically investigated the leaching behavior of bauxite lithium-rich beneficiation tailings in caustic solution, together with their phase and morphological changes. The main chemical compositions (mass percent) of bauxite flotation tailings were 40.56% Al2O3, 34.00% SiO2, 4.34% K2O, 3.31% TiO2, 1.83% Fe2O3, This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore. First, a series of batch grinding tests were carried out in order to investigate the grinding behavior of the ore and the effect of the material filling volume (fc) on the distribution of aluminium- and iron-containing phases.
