METHOD OF FLOTATION OF COPPER MOLYBDENUM ORES Russian patent published in 2008 - IPC B03D1/00 

FIELD: mining.

SUBSTANCE: method of flotation of copper-molybdenum ore incorporates bulk flotation of copper and molybdenum in alkali medium formed by lime. Bulk flotation is performed at presence of collector Aero-MX 3601 and a foaming agent. After operations of concentration and desorption at heating of pulp to 40-60°C with direct steam at presence of sulphureous sodium the concentrate of bulk flotation is directed to molybdenum flotation at presence of collector Aero-MX 3601, thus producing molybdenum concentrate by foam product. Rejects of molybdenum flotation are directed to copper flotation with employing of collector Aero-MX 3601 at presence of a foaming agent, thus producing copper concentrate and rejects of copper flotation.

EFFECT: upgraded efficiency and intensification of process of separation of copper-molybdenum ores.
