Recovery of Copper by Solution Mining Methods

A Brief History of Copper Recovery by Solu-tion Mining Methods As early as the 1670, copper-bearing mine waters at the Rio Tinto mine in Spain were known to chemically precipitate copper onto iron (Arbiter and Fletcher, 1994). This process became known as the “cementation process”, which is apparently derived from the Spanish word
