In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and there is no critical ...
At 11–14, students need to understand how metals are extracted, what an ore is, and reduction and oxidation. These worksheets help to build this knowledge, taking the extraction of iron, lead and copper as examples. Before you use these worksheets, you may find it valuable to read the Education in Chemistry article, How to teach the ...
An oxidized lateritic ore which contained 0.8 % (by weight) copper was bioleached in pH- and temperature-controlled stirred reactors under acidic reducing conditions using pure and mixed cultures of the acidophilic chemolithotrophic bacterium Acidithiobacillus ferrooxidans. Sulfur was provided as the electron donor for the bacteria, …
