[8] The complex is located in Magny-Danigon, on the outskirts of Ronchamp, in the Haute-Saône department of the Burgundy-Franche-Comté region of France.

Its position forms a triangle with the Chanois well and the Ronchamp thermal power station, both 200 meters away.

[16] It is then sifted and separated into two categories: the smallest fragments are sent to the coal preparation by conveyor belts, while the largest pieces are sorted by hand by women for direct shipment to customers.

On the other hand, if it is not sufficiently free of sterile material, it is crushed to form flakes measuring less than seven centimeters before being sent to the coal preparation.

The incandescent coke is dumped onto an inclined plane, where it is cooled by water jets before being discharged into railcars.

[27] The Coal preparation plant's ancillary buildings, notably the benzol vats, are in ruins, except for one part which had been converted into a dwelling and still has a roof in good condition.
