Reduction of Metals (Extraction from Ore) A-Level

Electrolysis. Ionic substances can be broken down into the elements they are made from by electricity, in a process called electrolysis.. For electrolysis to work, the ions must be free to move.When an ionic compound is dissolved in water, or melts the ions break free from the ionic lattice.These ions are then free to move. The solution or molten ionic compound is called an electrolyte.

Elution and Carbon Reactivation Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

Rust Removal by Electrolysis A Detailed Illustrated

In electrolysis, an electrode connected to the charger's positive terminal is called anode. The anode is also called "sacial" or "waste" electrode because it can be expected to disintegrate and visibly decrease in size during the process. The choice of a conductive object to be used as an anode in electrolysis should be considered carefully.
