Abstract

Carbochlorination was investigated as a means of extracting aluminum from byproduct plagioclase recovered from the tailing of copper-nickel processing. The effect of temperature and level of reductant and catalyst were determined using a thermogravimetric analysis technique and roasting in a horizontal tube furnace. Plagioclase was difficult to chlorinate even under the most favorable conditions of 2 moles of sodium chloride per mole of alumina, 50 percent activated carbon and fine particle size (less than 53 mu m). The carbochlorination behavior of other aluminum bearing minerals (gamma and alpha alumina and kaolin) is compared with plagioclase. Preliminary results of fluidized bed chlorination of plagioclase and alpha alumina indicate that this approach is not feasible.
