The pilot unit ΕΝΕΧΑL worked for 18 months, during which processed more than 35 tonnes bauxite residue. Dozens of experimental tests have been conducted, seeking to determine the optimal operating conditions for the furnace, in order to achieve: (a) The optimal production of pig iron, corresponding to 30% of the bauxite residue mass and (b) The production of fluid slag with specific physical and chemical properties allowing its use for producing rockwool.

The quantity of pig iron produced was successfully tested in the production of castiron spheres in a Serbian steel plant. The quantity of the rockwool produced was evaluated in Italy from producers of associated insulation material and was judged most competitive compared to similar existing products. The total of rockwool produced successfully exploited within the factory, as industrial insulating material.
