Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be increased in copper ores, so the appropriate depression of sphalerite floatability should be achieved to obtain saleable copper …

The Polish copper deposits in the Lubin-Sieroszowice region contain ca. 60 ppm uranium in the ore, while the copper concentration is 2%. Even though not all of these resources are available, the possibility of uranium recovery encourages other metal extraction by leaching from waste streams. 2. Material and methods.
