History 
Maria Elena is named after Mary Ellen Comdon, the wife of the first saltpeter refinery works (oficina salitre) manager, Elias Cappelens. Originally, the name of the works was "Coya Norte". Situated on land purchased from the Treasury in 1924, the plant was opened in 1926 using a sodium nitrate extraction system patented by the Guggenheim Brothers which had replaced the Shanks system. It was laid out on the basis of the flag of the United Kingdom. Together with the former refinery at Pedro de Valdivia built in 1931, it was the largest saltpeter works with a combined output of over one million tons per year.

In 1965 both were taken over by the state, through the Sociedad Química y Minera (SQM or "Chemicals and Mining Company", which was privatized in 1980. This privatization explains why most land and buildings are owned by SQM and not by individuals or the Chilean state.

In 1996, it became the only active mining community in the country after the closure of the saltpeter works at Pedro de Valdivia, following which many workers and their families were relocated to Maria Elena.

On November 14, 2007, the area was devastated by a 7.7 Mw earthquake with an epicenter  north of Maria Elena. Almost all the town's old houses collapsed or were made uninhabitable, and the local hospital also almost completely collapsed, though with no loss of life or injuries.
