Placer mining involves dredging sediments from the water bottom to extract minerals.
What types of separation of mixtures explain?
These processes are based on a single principle: the difference in density between the components of the mixture. They are often used together to separate heterogeneous mixtures of two types: liquid + solid and immiscible liquids.
In this case we have what mixture is the sediments of stones and the water that through the sieve will separate one from the other.
