The Sintering and Leaching of Low-Grade Diasporic Bauxite

An improved lime-sintering process was developed to produce alumina from low-grade diasporic bauxite in this paper. Both clinkers sintered by the real bauxite and simulated bauxite at 1350 °C when the molar ratio of CaO to Al2O3 decreased to 1.4 were produced, the alumina leaching rates of which reached over 90% in sodium carbonate liquor. The main phases in the clinkers after sintering are

A novel process and its mechanism for recovering alumina

May 01, 2017· 1. Introduction. Unlike bauxite ores found in other countries, most of the bauxite ores in China are diasporic, which are refractory and characterized by their high silica contents, low mass ratios of Al to Si, and high crystallinity (Authier-Martin et al., 2001, Li et al., 2015, Cao et al., 2013).There are a number of problems in treating such refractory ores using the conventional Bayer process:
