Resumen de Calcined bauxite: : In the hands of a few
Refractory-grade bauxite production is estimated to be around 2m tpa. Guyana and China are the top producers of calcined bauxite for refractories. According to the USGS, Guyana produced around 1.6m tonnes bauxite, which includes refractory grade bauxite, in 2014. In 2012, global reported bauxite production peaked at 2.2m tonnes.
"Exports in 2012 totalled more than 610,000 tonnes at an average value of $308/tonne FOB China. By the end of 2013, exports increased to nearly 770,000 tonnes, but the average value fell to $261/tonne," she adds. "This trend continued into 2014, when exports surged again to nearly 870,000 tonnes, but values inched down slightly to $252/tonne.
