Metal Ore
For most metals the process of changing from the ore form to the metal form is to use heat to drive off the oxygen and other components that have combined with the metal ore. Processing of the metal ore forces the electrons from other ions (oxygen, etc.) that are being removed by the process to attach to the outer shell of the metal ion to form ...

Process for recovering metals from refractory ores
The present invention is a process to recover metals from refractory ores. It involves the chlorination of an ore concentrate in the presence of solid salt at a temperature between 300° and 650° C. Thereafter, an oxidation step can be used to convert iron chloride to iron oxide. Subsequent separation steps remove the salt, gangue, and iron oxides.
