Silver processing | Britannica
From copper concentrates. The smelting and converting of copper sulfide concentrates result in a "blister" copper that contains 97 to 99 percent of the silver present in the original concentrate. Upon electrolytic refining of the copper, insoluble impurities, called slimes, gradually accumulate at the bottom of the refining tank.

Innovations: Introduction to Copper: Mining & Extraction
Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest ...

copper extraction and purification
Electrolytic refining. The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper.

Copper production & environmental impact
• Copper is recyclable without loss of quality • Copper is the most recycled metal after iron and aluminium • Around 40% of the demand for copper within Europe is supplied from recycled copper. • Recycling a tonne of copper uses 20% of the energy that would be used to mine and extract the same copper.

Only silver conducts electricity better than copper, traditionally Silver cost 40 times the price of Copper. Refining improves the conductivity of copper by lowering the electrical resistance.Resistance is like friction to electricity, and it causes energy to be lost as heat in poorly conducting wires.

Step 1. Ore is taken out of the ground. Holes are drilled in the ground (if it's an open-pit mine) or in the rock-face (if it's an underground mine), and explosives are placed in them to blast it open.The resulting explosions leave huge quantities of copper-bearing rock – also known as ore.
