A Step-by-Step Guide to PCB Manufacturing Process
Copper Plating (Copper "Pattern" Plate) Copper plating is a process of depositing copper on the exposed copper circuit through an electrical process. The thickness of deposited copper depends on the needed final finish of the circuit board. However, the most commonly deposited amount of copper is 1mil (0.001). Tin Plating

Copper Beryllium Alloys
Heat treating is key to the versatility of the copper-beryllium alloy system. Unlike other copper-based alloys which acquire their strength through cold work alone, wrought copper-beryllium obtains its high strength, conductivity and hardness through a combination of cold work and a thermal process called age hardening.
Copper Mining and Processing: Background
Copper is a chemical element in the periodic table with the symbol Cu (from the Latin word cuprum, meaning 'metal of Cyprus,' where it was mined during the Roman era).Copper has an atomic number of 29 and atomic weight of 63.54 grams per mole. It is an element in Group 11 of the periodic table, sharing many properties with silver and gold.

How to Process Copper Ore: Beneficiation Methods and Equipment
There are different methods of processing copper mines, such as preferential flotation, bulk-separating flotation, etc. for copper sulfides, and sulphidizing flotation, fatty acid flotation, etc. for copper oxides.
The Copper Recycling Process
The other metals (sometimes valuable, but considered to be impurities in copper processing) either remain in solution or fall to the bottom of the tank, where they can be later captured for use as a by-product. Over the course of 1-2 weeks, the copper ions plate onto the cathode, resulting in a 300-pound sheet of 99.9% pure copper. "

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
