| Abstract: | Processes of ammonium hydrodifluoride interaction with main components of copper-nickel concentrates - iron, copper, nickel oxides have been investigated. Thermodynamics of chemical reactions was calculated. Thermogravimetric analyses were carried out. The main kinetic parameters - activation energy and interaction rate constant of ammonium hydrodifluoride with iron, copper, nickel oxides were experimentally determined. Manufacturing sequence allowing us to separate individual oxides from oxide mixture was proposed |
