Wohlwill electrolytic refining process for gold

2008-3-6  The most you can get for gold is 99.92% that is for single refining and only if you spend a long time putting a lot of nitric acid, usually it's between 99.60 to 99.80%. You can achieve 99.99% through electrolytic refining sometime called electrorefining.

Electrolytic Cell - an overview ScienceDirect Topics

electrolytic cell reaction: electrical energy + 2 H 2 O 2 → 2 H 2 O 2. In an electrochemical cell the overall redox reaction is composed of two half-reactions. One half-reaction, i.e. the oxidation takes place at the anode and the other half-reaction, i.e. the reduction is taking place at the cathode.

Galvanic and Electrolytic Cells

2012-4-5  Electrolytic Cells An electrolytic cell has an endothermic chemical reaction. The reaction is not spontaneous so a power source is required. Energy is stored in an electrochemical cell. That energy can be released when the cell is allowed to run in a galvanic mode. Above right is the galvanic cell

Electroplating - exo

2005-10-3  A system where an electric current produces chemical reactions is called an electrolytic cell. Electroplating, in which a metal is plated onto another object (e.g., chrome-plated trim or wheels on a car, chrome-plated bathroom fixtures, gold-plated or silver-plated jewelry) is an example of an electrolytic cell. This
