Reverse electroplating for environment-friendly gold recovery / refining

Q. I am about to embark on scrap circuit board recycling, primarily for the gold and platinum content. I am about to set myself up with an acid solution [aqua regia], that dissolves the precious metals, but is very dangerous to handle. It was recently brought to my attention that I could use a rectifier and salt solution to dissolve.

Gold from sea water (new technique) - Creativity Pool Forums

This can however become possible with the old electrolysis technique, with the only difference that the voltage difference between the electrodes must .. The concentration of gold in seawater is about 13 ug/m^3 (not 1.3 mg), so to extract one troy oz of gold you would have to process about 2.3 million M^3.

Electrolysis of water - Wikipedia

This is in part due to the limited self-ionization of water. Pure water has an electrical conductivity about one millionth that of seawater. Many electrolytic cells may also lack the requisite electrocatalysts. The efficiency of electrolysis is increased through the addition of an electrolyte (such as a salt, an acid or a base) and the.

How much would it cost to extract one ounce of gold from sea water .

Sea water contains about 0.1-2 mg/tonne of gold dissolved in water (average 1 mg/tonne). But considering the amount of seawater available, it is a really huge goldmine! Theoretically fine, but problems were practical (which prevented profitable extraction till now). This can however become possible with the old electrolysis.

How to Separate Salt from Water | Science Project | Education

In ancient times, salt was used as a form of currency in some cultures. During the period when the ancient Phoenicians controlled the salt trade in the Mediterranean, salt was as expensive as gold! In this lab, we will learn how to separate salt from water through a solar process—you can use the sun to evaporate water,.

Electrolysis - an overview | ScienceDirect Topics

Sprinson & Rittenberg (1948) reasoned that because of the very small isotopic fractionation of oxygen during electrolysis it is possible to use this method to produce O2 from water for isotopic measurement. Bentley (1949) presented a microelectrolysis method in a U-shaped glass tube with separate production of H2 and O2.

Electrolysis of Salt Water - NASA Aquarius Mission - University of .

In chemistry, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. An ionic compound, in this case salt, is dissolved with an appropriate solvent, such as water, so that its ions are available in the liquid. An electrical current is applied between a pair of inert.
