process of stabilisation / solidification, with a matrix of inorganic waste, from the treatment of aluminum.

摘要

A process for stabilizing and solidifying wastes from aluminum processing by means of an inorganic matrix, comprising mixing said wastes with water, lime, cement and one or more natural pozzolan materials, such as real pozzolans, pozzolanic tufa and diatomaceous earth, or artificial pozzolan materials, such as fly ash, in well-defined proportions by weigth, said process further comprising treating the gas that gradually evolves during the mixing step by means of a gas scrubbing or purifying system.
