Mechanochemical activation of serpentine for recovering Cu (II) from wastewater

The serpentine is a kind of layered silicate minerals, when the raw material of serpentine activated by the grinding operation, it would change to be amorphous gradually. After the treatment of copper(II) solution by the activated serpentine, the formation of wroewolfeite phase as the copper precipitate confirms that a chemical precipitation has occurred during the copper removal from the solution, explaining the higher capacity of the activated serpentine than the raw material.133
