flotation copper problems

The problem of the flotation of oxidized copper ores has not yet been solved One or two special processes are in operation for the flotation of malachite and azurite but none of them has more than a limited application nor has any method been worked out on a large scale for the bulk flotation of mixed oxidized and sulphide copper minerals when the former are present in the ore in appreciable quantity
