The Duc Bo Copper-Zinc Mine, located in Quang Nam, Vietnam, is currently not operational and there are no known plans to resume mining activities in the near future. The mine is situated in an area dominated by gneiss, a type of metamorphic rock formed during the Neoproterozoic era approximately 1.00 to 0.54 billion years ago.
As shown in the summary tables, copper was, on average, 63% recovered into the copper concentrate grading 24% copper. The recovery and grade of unwanted lead and zinc was very low when compared to the other …
Fig. 1 shows the effect of pH on the extraction of cadmium, copper, lead and zinc complexes. It was found that for copper and zinc in the pH range 7.0–10.0, lead in a range 7.0–9.0 and cadmium in the range 8.0–10.0, extraction was quantitative. Hence, a middle range of pH at 8.6 was chosen for these analytes. Download : Download full-size ...

One key feature of underground space development is the need to excavate huge amounts of rocks. For instance, the 9.4-km long Katzenberg railway tunnel built between Karlsruhe, Germany, and Basel, Switzerland excavated approximately 2.3 million m 3 of rocks and debris (Haid and Hammer, 2009). Table 1 summarizes the various rocks, sediments, and …
