Compañía Española de Minas de Río Tinto (CEMRT) was a Spanish company that operated between 1954 and 1970, mainly in the province of Huelva. Dedicated to mining activities in the Rio Tinto-Nerva basin, over the years the company diversified its business into other sectors. After consolidating its position, in 1970 it merged with another company, giving rise to the Unión Explosivos Río Tinto (ERT) group.
