Management of copper pyrometallurgical slags: giving ...

2004-1-18  The basic idea is to obtain a copper concentrate by usingflotation techniques. This process was used in the past stillexists as a slag treatment plant in Chuquicamata. Thistechnique was also used widely by small miners because itis a very simple and effective way to recover copper. Theslag flotation has become less important recently due to thedecreasing of copper content in final slags, this was causedby new optimization methods in smelting processes. InChile, Altonorte smelting plant,

Effect of Water Granulation Conditions on Density and ...

To secure the average diameter of 2.0 mm or more in water granulated slag, which could not be obtained by the water granulation plant for cement, we tried using a low blowing water velocity. Figure 22 shows the relationship between the average diameter of the water granulated slag and the blowing water velocity in the new equipment. The decrease in blowing water velocity is effective for producing coarse water granulated slag.

Design and Operation of Dry Slag Granulation Pilot

2019-2-22  CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed to a counter-current moving packed bed heat exchanger, where they are further cooled and finally discharged at close to ambient temperature.
