1. aluminium ore extraction . First, the so-called grinding a mixture of aluminium ore bauxite and sodium hydroxide it. Pump pressure the mixture into a large tank, where the mine will be broken down into a solution of sodium alumninate and legacy pollutants. Next, the tanks and presses through the solution set. Disposal of trapped pollutants. Transfer to solve a cooling tower. Mobile solve a silo, and add aluminum hydrate crystals, which will attract more crystals from the solution, the formation of aluminium hydroxide. Filters, washing and thermal exposure at high temperatures. The dehydration will produce aluminum oxide.

2
Smell compounds, the first step in the production. Melting the aluminum oxide cell, the cell is carbon steel, and containing a liquid is heated conductor closed. Current generated by the crust, you will continue to fall off, dissolved, stirring inch aluminum will be created in the bottom of the aluminum mold. And input of aluminum melting pot, where you can add other elements of the alloy. There will be cast into the cold and then heated container. Scroll to the foil.

3
Extruded aluminium foil rolling mill and extrusion to the correct thickness. Occasionally, to maintain flexibility in the heating foil. The foil touches the surface of work roll surface, it creates a shiny completed, two will be rolling with the moving matte finish on both sides. At this point, trim the edges of foil, cut into small pieces of debris
