Xstrata needed to improve copper recovery and called on Orica to identify and test collectors. Orica formulated a collector that would enhance milling and flotation of slow cooled copper slag. Ultimately, the process needed to achieve superior recovery of copper at a natural pH over a specific grind fineness. Xstratas key requirements were to
Mar 15, 2019 In terms of copper recovery, it is thus quite important how the copper slag has been processed and cooled post the smelting or converting furnace, EF and prior to the milling and flotation step. Far less important, in this respect, is the actual smelting and converting technology upstream of the slag cleaning step.
Slags are sometimes treated by slow cooling, milling, and flotation. This approach is satisfactory when the metals in the slag are in either the sulphide or metallic form, but is not suitable for the recovery of oxidized metals.
Laboratory flotation tests of slow cooled converter slag have showed that 92.5% copper recovery at the copper cut-off grade of 24-25% can be achieved by using a 5050 ratio of DSP330 and SIBX ...

The loss of matte to flotation tailings late in 1999 was mainly due to its being locked in silicate or surrounded by an oxidized rim. Recent examination also shows the presence of oversized free matte particles in the tailings these may not have floated due to their mass. Slow cooled slag samples Pot and spoon samples of furnace slag were ...

Feb 03, 2021 Flotation of Copper From Slow-Cooled Converter Slags. The results of flotation tests on slags cooled in air and in the induction furnace are shown in table 2-3. Examination of the data indicates that a relatively fine grind is required to liberate the entrained metallic particles. A 30-minute grind resulted in 98 percent of the pulp passing 200 mesh.
9, 10, and bioleaching 11 have been proposed. Milling and froth flotation methods are quite common when dealing with slow-cooled slags. Before flotation, the slag needs to be cooled inacontrolledmanner. Therearemultipleoptionsforthis,such as natural cooling, casting mill cooling, water quenching, and
Jul 31, 2020 Milling and froth flotation methods are quite common when dealing with slow-cooled slags. Before flotation, the slag needs to be cooled in a controlled manner. There are multiple options for this, such as natural cooling, casting mill cooling, water quenching, and slow cooling in a ladle .
Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag. ... Recovery of copper from slow cooled ausmelt furnace slag by floatation. Characterization of Minerals, Metals, and Materials 2015,
C) with 23 wt% Cu remaining in the smelting slag. At present, the recovery of copper from slag is processed by slow cooling, milling and flotation at Fangyuan. Bottom blown oxygen copper smelting technology has demonstrated great potential and will be transferred to other plants around the World.
cooling), and N 2 natural convection (slow cooling). Finally, after solidification, representative samples of formed matte and remaining slag were taken and characterized by using optical microscopy, SEM, XRD, XRF and ICP. Copper Slag Processing controlled cooling of copper slags prior to flotation treatment
flotation tails between 0.2 and 0.3 wt-% (Vehvilinen et al. 2000). The mineralogy of the granulated slags is mostly glassy and the fraction of crystalline phases is small, whereas the slow cooling technology in ladles (Subramanian Themelis 1972) is often combined with the slag milling and flotation. It generates a coarse
treated by slow cooling, milling, and flotation. This approach is satisfactory when the metals in the slag are in either the sulfide or metallic form, but is not suitable for the recovery of oxidized metals. Cobalt and zinc, in particular, and nickel, to a lesser extent, are found in an oxidized form, and for these slags,
The smelter objective is to process wet concentrate to produce crushed, slow-cooled, sulphur-deficient nickel-copper matte rich in platinum group metals, ... gangue from the converter, while a slag milling and flotation circuit treats the slag from the electric furnaces.
controlled cooling, grinding and froth flotation, where the cooling rate is an important variable of control because it has effects on sedimentation and coalescence of the entrained valuables, and crystallinity of the slag matrix, as well. As a result of the controlled cooling stage, a sulphur phase of copper matte precipitates and solidifies,
