The foundries

In the early of the 20th century, following a new attempt to resume mining, new foundries were built in Valpelline on the orographic left of the river.
Between 1905 and 1906 the construction of a large sleeve oven with fourteen blowing mouths, capable of treating 60 tons of material daily, began.
The treatment of the mineral is carried out according to the German method of roasting and reducing in sleeve ovens.
The furnaces and roasting furnaces are connected to a chimney leaning against the mountain, which allows to bring sulfur dioxide to a height of about 100 meters from the foundry floor.
During the mining period, the ru Pompillard, which passes close to the foundries, is used to supply water to the plants.
The path that follows the site of the canal also allows direct connection with the foundries of Quart where, on land owned by count Perrone, the factories are built for the further processing of the extracted material.
