How would you separate a mixture of sand, iron nails, and sea salt We all know that nails are attracted to magnets. So first, use a magnet to attract the iron nails. We also know that salt dissolves in water, while sand does not. So add water to dissolve the salt and leave out the sand. Now, filter the sand out, and then heat the salt solution ...

Decanting. Decanting involves separating a dense, insoluble substance from a heterogeneous mixture. For example, if we mixed sand with water in a beaker, the sand would not dissolve, but would settle to the bottom, forming a sediment layer. By gently pouring off the water the supernatant, we could separate the sand from it. In the laboratory, using a glass rod can assist the decanting ...

For example, a mixture of sand and gravel is separated using a sieve and works because the gravel particles are much larger than the sand particles. When a strainer is used the process is referred to as straining. For example, straining the spaghetti from the water after cooking. There are many practical examples of separating mixtures by ...

This method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles. Sieve plates have meshed or perforated bottoms which allow only particles of a specific size to pass through it.

These are composed of iron oxides, which we try to reduce, and the unwanted ‘gangue materials’ which take the form of silicates and alumina, in other words the ‘rock’ part of the ore. Besides oxides, which are oxidised iron, iron ore also occurs in the form of sulphites and carbonates.

The separation process of winnowing was used in ancient cultures to separate the grain from the chaff. They would throw the mixture into the air and the wind would blow away the lighter chaff, leaving the heavier grain. High speed centrifuges can spin up to 30,000 times a minute. Many separation processes are occurring constantly in nature.
