  • PROCESSES FOR EXTRACTING ALUMINUM FROM ALUMINOUS ORES
    Publication number: 20140065038
    Abstract: There are provided processes for extracting aluminum ions from aluminous ores and for preparing alumina. Such processes can be used with various types of aluminous ores such as aluminous ores comprising, for example, various types of metals such as Fe, K, Mg, Na, Ca, Mn, Ba, Zn, Li, Sr, V, Ni, Cr, Pb, Cu, Co, Sb, As, B, Sn, Be, Mo, or mixtures thereof.

  • PROCESS FOR EXTRACTING ALUMINUM FROM ALUMINOUS ORES
    Publication number: 20130233130
    Abstract: There is provided a method for extracting aluminum ions from argillite. The process comprises leaching the argillite with an acid such as HCl so as to obtain a composition comprising the aluminum ions and iron ions; at least partially removing the iron ions from the composition by substantially selectively precipitating the iron ions by adding a base and at least partially removing the precipitated iron ions so as to obtain an Al-rich composition; and optionally purifying the Al-rich composition by adding a base for substantially selectively precipitating the aluminum ions, by means of a hollow fiber membrane, or by a liquid-liquid extraction.
