US: Cemtech Materials will produce cement using bauxite residue supplied under a new contract signed with New Day Aluminium Holdings subsidiary Noranda Alumina. Noranda Alumina has executed a letter of intent with Cemtech to sell it 60,000t of bauxite residue starting in the fourth quarter of 2020. The bauxite will be used in the cement production process as the raw material for iron, replacing other current iron bearing raw materials.
Noranda Alumina chair and chief executive officer (CEO) David D’Addario said, “We are focused on continuously improving the sustainability of our business and reducing our environmental footprint on our path to a zero residue refinery, and look forward to helping our partners in the cement industry to achieve their aligned goals.”
The deal follows a beneficial use approval from the Louisiana Department of Environmental Quality. Noranda Alumina is located in Gramercy, Louisiana. It produces smelter grade alumina for the production of aluminium and chemical grade alumina for non-metallurgical applications.
