In order to produce a copper (pre)concentrate, flotation tests were carried out in the laboratories of the AMD of the RWTH in Aachen. A Denver D-12 flotation cell with a volume of 2.5 L was used. The feed was usually 0.5 kg per test, one time 1 kg and one time 1.4 kg.
One of the most important factors when selecting the collector is the mineralogical composition of an ore. Due to the complex nature of mineral deposits, the common strategy is to combine various collector types (Rao and Forssberg, 1997, Bradshaw et al., 1998, Bağcı et al., 2006, Liao et al., 2024).The feed ore composition can change over time, leading to variations …

As shown in Table 2-1 the major copper ore present in the LJ ore was chalcopyrite with a significant amount of other copper bearing minerals whereas in the DX ore the chalcopyrite was slightly less than LJ ore (1.22% compared to 1.35%) but there were little other copper minerals present. Diagnostic leaching tests were carried out to estimate ...
Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to …
