2. Let’s Learn Different types of matter can be combined to form mixtures. Because of the physical properties of matter such as size, shape, and density, mixtures can also be separated back into different types of matter.

3. Solid-Solid Separation Methods Some of the common separation methods used in separating mixtures of both solids are the following: 1. Sieving Sieving , also known as sifting , is the process used to separate solid particles of different sizes. In this process, the mixture is placed on a mesh of a particular size in order to separate its particles. The tools used in sieving are called sieves or sifters . These tools have small holes or a wire mesh at the bottom. The one used for sifting flour has very small holes.

4. 2. Magnetization Also called magnetic separation , magnetization is the process of separating metallic components in a mixture from nonmetallic components. Some examples of metals are iron, nickel. And cobalt. Due to their magnetic properties, they get easily attracted the iron f illings, since iron has magnetic properties. Those metals which do not possess magnetic properties do not get attracted to magnets. Some examples of such metals are gold, silver, and aluminum.

5. Benefits of Solid-Solid Separation Methods in Making Useful Products Baking . In baking, sifting the flour is a must. Sifting flour can remove debris or unwanted materials. It can also break up any clumps in the flour and aerate it at the same time.

6. 2. Construction sites . Sieving is also used in construction sites. This process is used to separate gravel and sand for the construction of houses, buildings, and other structures.

7. 3. Food Industries. Sieving is also done in food industries. This is done with the use of sieving machines, most of which are vibrating. These machines help prevent foreign bodies from contaminating products.

8. 4. Mining ore. Magnetization is used in mining ore. Through this process, unwanted waste metals are separate from the useful ore. Mines use magnetic separators to do this. Magnetic separators are also being used in food and drug processing industries. Through these machines, metal contaminants are removed from product streams.

9. 5. Food and drug industries. Magnetic separators are also being used in food and drug processing industries. Through these machines, metal contaminants are removed from product streams.

10. 6. Separating Scraps. Magnetization is applied by electronic cranes too. These are machines that separate magnetic materials from scraps.
