Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal

Having a quick look now at how porphyry ores are treated and the metals extracted.
descriptions of the most common methods. 184.108.40.206 Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit

[GIFS] The 5 Stages of the Mining Life Cycle Operations
This is the process of extracting the ore from rock using a variety of tools and machinery. The second step is processing. The recovered minerals are processed through huge crushers or mills to separate commercially valuable minerals from their ores. Once processed, the ore is then transported to smelting facilities.
