Fluor helps bauxite mine get set - Mining Magazine

It took a 200-person team to complete the massive project, which will serve a large role at the complex. Bauxite is transported from the mine to Port Kamsar by rail, where it is shipped to customers. At the port, the car dumper facility unloads bauxite from the rail wagons, and the newly placed rotating assembly is critical to that effort.
