When the mass ratio of copper ore to red mud is 10.9:89.1 with the corresponding mass ratio of copper ore to iron ore being 20:80, it is theoretically possible to achieve autothermal balance in the FR [41]. The addition ratio of 20 wt% cement is determined on the basis of our previous work [34], [35]. In this case, the two composite OCs are ...
The iron liberated during the alteration sequence can remobilize to form goethite or limonite. These iron oxides and hydroxides are particularly prejudicial for flotation if they precipitate on the surface of the copper minerals because they are not collectable with xanthates (Woods, 2003). Table I. Copper minerals present at the Kansanshi Mine.

Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition. The problem is to convert the sulphide into the oxide form. ... Prasad and Pandey studied the roasting of the mixture of copper-iron sulfides and copper sulfide formed ...
Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...

BHP says the company had a "solid first half", with WA iron ore production up 5% quarter-on-quarter and first half copper production up 7%.. The production figures were relatively mixed against consensus expectations but likely eclipsed by downbeat economic data from China and the recent resurgence of the US dollar.
