Sealed Air

Atlas Copco's oil-free compressors deliver ISO 8573 Class 0 air for pharmaceutical and food-grade nitrogen production. PSA nitrogen generators — our zeolite beds separate N2 from O2 on demand. Purity controlled by molecular sieving.

Froth flotation chemistry separates copper ore from gangue — xanthate collectors selectively bind to sulfide minerals, attaching them to air bubbles. Without these molecules, battery-grade copper stays in the rock.
