Business Model & Process

Zimalco is South Africa’s largest manufacturer of secondary aluminium products.

Production processes are divided into 3 distinctive streams where the various grades of aluminium scrap are sorted, smelted, alloyed, atomised, processed and blended to meet international and customer specifications:

• Scrap is sorted, smelted and alloyed to produce specification alloys for the foundry and die casting industries and for use as deoxidants in the manufacture of steel.
• Primary and commercial scrap is melted and atomised to produce aluminium powders of various fraction sizes which are blended to meet customer specifications for the production of explosives and various chemical and exothermic applications.
• Aluminium drosses are processed to recover the metal content and to convert them into a product that can be used as a raw material input for downstream industries thus preventing the disposal into hazardous waste sites and keeping the company 'GREEN'.
