Aluminium

Aluminium is, due to its properties, the second most used metal after iron. Recycling is a major aspect of continued aluminium use, with more than a third of all globally produced aluminium currently originating from old, traded and new scrap.

ALTEK's R&D team is working with our European partners to create new and innovative solutions to this growing problem.

AluSalt

Salt cake is a by product in the aluminium recycling process using a rotary furnace. Salt cake is a mixture of aluminium oxides and aluminium nitrides, metal and salts (mainly NaCl and KCl, with small amounts of MgCl2 and CaCl2). The salt cake is a growing environmental problem and companies producing this material face excessive fuming, storage problems and environmental hazards.

ALTEK are focusing on the most effective way to reduce these immediate issues using a Salt Slag Press and special cast steel slag pans. By immediately pressing the salt slag in a 10-15minute cycle, the fuming and forming of nitrides are significantly reduced, more aluminium can be recovered, and the rapid cooling will allow the pans to be tipped in a matter of hours. In addition to this, storage is greatly improved by stacking the salt slag skulls, pan maintenance and expenditure is reduced, and companies can reclaim large areas of the cast house taken up by cooling pans (typically taking 36+ hours cooling naturally).

Data testing at installations around the world have given great insight into the sizes and designs required to effectively press a wide range of salt slag production. The most recent development project has focused on the larger capacities where ALTEK are pleased to announce that quantities up to 2.5T of salt slag can be processed in only one pan. This process turns the hazardous waste into a valuable commodity.
