METHOD OF FLOTATION OF FINE-IMBEDDED LEAN COPPER AND GOLD-CONTAINING ORES

摘要

FIELD: mining industry. SUBSTANCE: method includes preliminary slurry formation, conditioning slurry with hydrophobic collector and froth-formation agent, and subsequent removal of collector with useful components bound to its surface into froth product. As hydrophobic collector, coking coal with particle size at most 0.8 mm is used, this collector being repeatedly reused to come into contact with fresh slurry on condition that standard saturation of collector with useful components is provided. EFFECT: reduced expenses and improved environmental safety. 6 tbl
