The effect of ball milling process on the properties of the natural local clay including structural changes and adsorption capacity for the removal of Ni(II) ions from aqueous solutions, was investigated. The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6).
