RUSAL Challenge Cost-effective Processes to Recover and

Jan 19, 2017Salt cake ('slag') is a toxic and hazardous by-product generated during aluminum processing. It is mainly composed by salts (KCl and NaCl) that, instead of being wasted in landfills, can be recovered and re-used in the process. Hence, RUSAL is seeking for a cost-effective process to recover and recycle the salts present in the salt cake.

SOLUBILITY OF ALUMINA IN MOLTEN CHLORIDE

Thus to recover aluminum metal from scrap in aluminum recycling, cryolite in the salt flux plays important role not only in lowering the interfacial energy between oxide layers and the aluminum melt, but also in increasing the solubility of oxide in the molten slag. Higher solubility of oxide in the salt melt normally leads to higher metal recovery.

The Cost of Slag Fabricating and Metalworking

When a laser is used to cut flat sheet metal, molten material called slag is produced as a byproduct of the thermal cutting process. As the laser moves away from the cutting site, this slag begins to cool, harden and solidify on the slats that support the material. Depending on the frequency that the laser cutting machine is used,
