General Information

Magnetite is a naturally-occurring mineral prominently known as one of the most abundant iron ores. It is an iron oxide that occurs in black aggregates and has magnetic properties that can be used in coal washing applications.

A positive surface charge attaches magnetite to the negative surface charge of decay materials, eliminating the turbidity of the water and removing the toxic materials.
