1. Prospecting and Exploration (“Finding and Defining it”) Prospecting and exploration are precursors to mining and often occur simultaneously; together, they can take two to eight years to complete, and may cost from $500,000 to $15 million overall. Prospecting is the process of searching the region for mineral deposits. Historically ...

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

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
