copper tailings are relatively poor. Due to this deficiency, the copper tailing has been either piled up or stored in dams, which requires complex structures and huge investment, as well as cost ...
cess route to produce magnetite pellet feed from copper o-tation tailings stored in a downstream raising dam located in Pará state in northern Brazil. Currently, the industrial plant processes 10.7 Mtpy of copper ore containing a feed grade of around 0.85 wt% of Cu, generating close to 10.4 Mtpy of copper tailings. The copper otation tailings con-
Fig. 3-Splral tests on desllmed oxide tailings and recovery of the lead minerals, which have a higher relative density, again surpassed those for copper or zinc, the recovery of copper and lead being 25 and 28 per cent respectively at a grade of 5 per cent each. The recovery of copper dropped off rapidly as the grade of the con-
Open the process water valve so that the pressure is within the operating range (70-120 kPa / 10-17 psi). Press the "run" button. The bowl will start spinning
The copper tailing (CT) samples were collected from rougher flotation tailings at a major copper producer in the USA. T wo sample batches were provided with a time
A flowchart for the copper recovery from flotation tailings using flotation‒high‒pressure leaching‒solvent extraction Based on the results from the experiments conducted and described in the preceding sections in this paper, a flowchart for recovery of copper from the flotation tailings can be proposed as shown in Fig. 17.
This work aims at the recovery of residual copper from low grade tailings (up to 5% copper, and high grade in polymeric material), by applying simple physical methods to counterbalance the relatively increased cost of the subsequent chemical treatment. The tailings originated from waste electrical cable treatment for copper recycling.
Copper cementation is described by the following reactions (Stefanowicz et al, 1997): Cu2þ þ Fe0 →Cu0 þ Fe2þ 0 The samples used during the tests originated from the tailings of a recycling plant dealing with the recovery of copper from electrical cables, after comminution to less than 4–5 mm and subsequent airseparation of copper wires ...
