ΜΕΛΕΤΗ ΤΗΣ ΣΥΜΠΕΡΙΦΟΡΑΣ ΤΩΝ ΑΝΘΡΑΚΙΚΩΝ ΟΡΥΚΤΩΝ ΤΟΥ ΜΑΓΝΗΣΙΟΥ ΚΑΤΑ ΤΗΝ ΕΠΙΠΛΕΥΣΗΤΟΥΣ

A RESEARCH STUDY HAS BEEN CARRIED OUT ON THE FLOTATION BEHAVIOUR OF MAGNESITE AND DOLOMITE WITH SODIUM OLEATE AS COLLECTOR. THE EFFECT OF THE MODIFIERS: SODIUM PYROPHOSPHATES, SODIUM HEXAMETAPHOSPHATE, SODIUM SILICATE, SODIUM FLUOROSILICATE, CARBOXYMETHYLCELLGLOSE AND CALCON ON THE FLOTATION OF THE MINERALS WAS STUDIED. INITIALLY THE FLOTATION OF PURE NATURAL MINERALS AND THE MAIN PARAMETERS WHICH INFLUENCE IT WERE STUDIED. THE CONDITIONS WHERE THE RECOVERY OF THE TWO MINERALS WERE SIGNIFICANTLY DIFFERENT WERE ESTABLISHED. IN THESE CONDITIONS THE FLOTATION OF ARTIFICIAL MIXTURES OF DOLOMITE-MAGNESITE WAS STUDIED. THE FLOTATION OF ARTIFICIAL MIXTURES OF MAGNESITE-QUARTZ WAS ALSO STUDIED. GOOD BENEFICIATION OF MAGNESITE WAS FOUND IN BOTH CASES. IN PARALLEL THE ADSORPTION OF SODIUM OLEATE ON THE MINERALS THE ZETA POTENTIAL OF THE MINERALS AND THE CONTACT ANGLEWAS STUDIED AND THE RESULTS WERE COMPARED TO THE FLOTATION RESULTS AND WERE FOUND IN GOOD AGREEMENT.
