The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns. This has resulted in the generation of large quantities of electronic waste (e-waste) that needs to be managed. The handling of e-waste including combustion in incinerators, disposing in landfill or exporting overseas is no longer ...
Dec 29, 2017· E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium (Pd) and platinum (Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components. E-waste is classified as hazardous material therefore should be managed properly.
The high temperature and high-pressure desorption method is to install the gold-loaded carbon in a pressure vessel, and mix the solution with 0.4% to 1% NaOH and 0.1% NaCN, heat temperature to 130 to 160 ° C, under the pressure of 3.6 to 5.9 kg/cm2. Within 2 to 6 hours, the gold and silver desorption rates of gold-loaded carbon exceeded 90%.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Abdullah M. Aitani, in Encyclopedia of Energy, 2004. 2.2 Crude Oil Processing. As a first step in the refining process, water, inorganic salts, suspended solids, and water-soluble trace metal contaminants are removed by desalting using chemical or electrostatic separation.This process is usually considered a part of the crude distillation unit.

Two (2) major techniques for refining gold Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

Slime generated in the electrolytic refining process contains precious and rare metals such as gold, silver, slenium, tellurium, etc. ...
An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and ...
Dec 29, 2017· Purification of Impure Copper can be Achieved by Electrolytic Refining What is impure copper: The smelting process takes copper ore and processes it into metal. This metal (sometimes called "blister copper" contains other metals (impurities) which often include valuable metals as gold, silver, arsenic, platinum and others.
Gold NPs aggregated as the zeta potential approached 0 mV because of reduced electrostatic repulsion between NPs. The authors performed the zeta potential measurements using a Malvern Nano ZS instrument equipped with a HeNe laser operating at 632 nm wavelength and a scattering detector at 173 degrees ( Ansar et al., 2017 ).
Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution.
Electrostatic Slag Refining This is a modern and special steel manufacturing processor for high quality steel required in special application like nuclear, missile, battle tank, Ships etc.
