HYDROMETALLURGICAL PROCESS FOR THE PRODUCTION OF COPPER
We claim 1. A hydrometallurgical process for the production of metallic copper comprising a reduction stage in which materials containing copper-iron sulfide ore concentrates are introduced into an aqueous chloride solution containing cupric chloride to solubilize part of the copper in said materials and reduce a substantial portion of the cupric chloride to cuprous chloride, the total

Detailed Procedures of Plating Copper for PCB
Sep 14, 2018——Technical Analysis of Plating Copper for PCB Processing. Electroless plating is widely used in the printed circuit board (PCB) production and processing which has holes on that and it can also be called PTH(Plate Through Hole), the main purpose is to deposit a layer of copper through a series of chemical treatment methods in the conductive substrate, and then increasing the thickness of

Copper Mining and Extraction Sulfide Ores
Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

Copper
Copper is the best non-precious-metal conductor of heat and electricity on the planet, so items that contain copper tend to operate more efficiently. According to the International Copper Association (ICA), using more copper in motors and appliances can reduce carbon dioxide emissions by 1.25 gigatonnes – equivalent to taking half a billion
