<p>The utility model concerns to mining industry, in particular to technologies of enrichment of wastes and tailings of processing factories. Technical effect of the utility model is to increase the economic benefit. Flotation tailings of copper ore with the copper contents of 0,07 % and gold 0,5 g/t are preliminarily enriched in the centrifugal concentrator. The rough concentrate is received in amount 10 - 12 % with the content of gold 3,8 g/t and copper of 0,27 % which is crushed for 65 % up to fractions in size 0,074 mm and is enriched by a flotation method. The concentrate is received with the contents of gold 48,5 g/t and copper of 7,8 %.</p> |
