Separation of Mixtures Good Science

The formation of a mixture is a physical process. (Images Benjah bmm27, Cjp24, LHcheM Wikimedia Commons) 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.

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
