Gimpex contributes to the aluminum industry by supplying vital inputs in both primary aluminum production and refining processes. We supply critical minerals used across the aluminum production chain. Bauxite is the primary ore for alumina and aluminum extraction through the Bayer process. Limestone is used as a flux in alumina refining and helps neutralize acidic waste streams. Quartz is essential in refractory linings and castable used in smelters and high-temperature processing units. Bentonite is used in green sand molds and pelletizing, supporting foundry operations and secondary aluminum processes. Cenosphere, with its lightweight and insulating properties, is used in insulating castable and low-density refractory concretes, enhancing energy efficiency in smelting and casting.
