Abstract
By noncontact measurement of crystal surface charge and with specific–designed equipment, the authors examine effect of model water systems having various physico–mechanical properties on the value and sign of charge of diamond and zirconium crystals. Experimental substantiation is given to the applicability of products resulted from electrolysis of water to the controlled change of surface charge of diamond and minerals with close physical properties during their electric separation owing to the increased difference of electric properties of the separated materials.
