Mulpún is a coal mine and locality in Los Ríos Region, Chile.
Mulpún lies in the commune of Máfil a few kilometers to the west of the Chile Route 5 and north of the Calle-Calle and San Pedro River.
The mine was exploited during parts of the 20th century when its coal powered the electric grid of the city of Valdivia.
[3] An underground coal gasification project in the closed Mulpún mine was made public in 2009[4][5] but was put on hold in 2013.
[2] Geologically the coal layers of Mulpún are belong to the so-called Mulpún Beds,[7] a unit similar to the Pupunahue Beds[2] that extends across large of the sub-surface of Los Ríos Region and whose coal has also been mined at Catamutún and Pupunahue.
