Mining technology consists of the tools methods and knowledge used to locate extract and process mineral and metal deposits in the earth The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery

The patio process is a process for extracting silver from ore The process was invented by Bartolomé de Medina in Pachuca Mexico in 1554 The patio process was the first process to use mercury amalgamation to recover silver from ore It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas

However there are basically only two methods to mine gold 1 the centuriesold use of gravity combined with the addition of mercury amalgamation and 2 the comparatively recent use of cyanide The cyanide method dates to the 1880s et al Craig 2011 and therefore chronologically amalgamation must be reevaluated as the tech
