Jul 16, 2004· Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques
Separation of Mixtures. Since they are formed by physically combining substances, mixtures can be physically separated. For example, if a copper sulfate solution is boiled, the water evaporates away and the copper sulfate powder remains. The formation of a mixture is a physically reversible process.

Chapter overview. 2 weeks 'Mixtures' was first introduced in Gr. 6, so learners should already be familiar with these concepts. Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography).
