Dec 10, 2016· This phenomenon is supporting the statement according which the flotation efficiency is greatly influenced by variations in the feed water quality. Besides, one finds in the concentrate more cobalt (59%) than copper (43%) revealing a great sensitivity of malachite towards chemical species introduced in the pulp water.


Recovering Cobalt and Sulfur in Low Grade Cobalt ... - MDPI

In the flotation process, increasing the amount of collector is beneficial to improve the recovery of concentrate, but the excessive amount of collector will result in the flotation of other nonpurpose minerals, thereby affecting the grade of concentrate [17,18,19].With the increase of butyl xanthate dosage, the grade of cobalt–sulfur ...
