01-05-1999  Flotation reagents are added to the flotation feed in pump boxes prior to flotation. Nkana Concentrator uses Sodium Ethyl Xanthate (SEX) as a collector and D250 as a frother. At bulk flotation, a concentrate containing both copper and cobalt called the bulk rougher concentrate is obtained and the tails are disposed off.

Production of cobalt from copper-cobalt ores on the ...

01-09-2020  A specific cobalt flotation circuit is run at KCM’s Nchanga concentrator. The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11.

Major Mines Projects Nkana Mine

29-04-2020  At Nkana, the concentrator operates in a conventional manner, and has a capacity of 12 000 mt per day. Primary stage crushing of ore is done underground while the secondary and tertiary stage crushing takes place at the concentrator. Ball mills grind the crushed ore for subsequent flotation to produce a copper concentrate grade of approximately 30%.
