Abstract

In this research, the extraction of lanthanides from low-grade bauxite via mechanochemical and roasting methods has been studied. The addition of NaOH during mechanochemical process significantly increased the yield of collected rare earth elements. The effect of roasting process at temperatures in the ranges from 400°C to 1100°C was analyzed. The highest recovery values of lanthanide that extracted from low-grade bauxite at various temperatures and ratio low-grade bauxite and NaOH solid, with variations in the ratio of 1: 1 and 2: 1 were obtained for yttrium (∼95.6%), lanthanum (∼79.6%), cerium (∼54.7%), neodymium (∼81.8%), and samarium (∼80.0%) from the theoretical value.
