23.3: Hydrometallurgy. Hydrometallurgy involves the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials.This process is used in extraction of less electro positive or less reactive metals like gold and silver. Hydrometallurgy is typically divided into three general areas: (1) Leaching ...
The reaction of these processes can be written as: 2CuFeS2+2SiO2+4O2 → Cu2S+2FeSiO3+3SO2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2.
This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) (1) 2 C u F e S 2 + 2 S i O 2 + 4 O 2 → C u 2 S + 2 F e S i O 3 + 3 S O 2. The copper (I) sulfide produced is converted to copper with a final blast of air.

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
resulting in blister copper of 98.5 – 99.5 percent copper content. In the next step, the blister copper is fire refined by the traditional process route or re-melted and cast into anodes for electro-refining. The output of electro-refining is refined copper cathode, containing over 99.99 percent copper.

Following the lamination process, a PCB is a panel with blank, solid copper on the outer sides. The solid copper foil provides a conducting path for the plating currents that will deposit the copper in the holes and on the surface features. Leaving the two outer layers, aka "sides", unetched provides this current path.
