## Magnetic and Non-Magnetic Materials

Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).

Many young students will have had memorable but often confusing experiences with magnets and magnetic materials. Magnetic materials are regularly encountered around the home, often holding small objects on the kitchen fridge or keeping cupboards and fridge doors closed. Toys very rarely make use of magnetic repulsion. Many younger students are yet to form strong views or in many cases any views at all about how magnets interact with matter or each other. They do not see the need to discriminate between magnetic forces and electrostatic forces or gravity. To them, these often appear to be common experiences of the same invisible non contact force, usually only attraction. Understandably their naive model has no predictive or explanatory power and they typically do not perceive the need to do more than identify and label the attractive or the less frequent repelling behaviour as magnetic.

Be sure to do the science projects below to learn how and why magnets work! Try this experiment to learn why. By measuring how far the magnet was from the paperclip when they become attached, you were finding the length of the magnetic field. Stronger magnets can generally attract magnetic materials from a farther distance than weaker magnets can. Based on that fact and the results you wrote in your notebook, which of your magnets was the strongest? Which one was weakest? A good way to test how strong different magnets are is to see how many magnetic objects it can attract.

One of the greatest challenges facing the mining industry is the separation of unwanted material generated by the extraction process from the valuable material. Mining, whether done through open seam or underground means, creates a huge amount of waste product in the form of worthless or low value minerals and unusable man-made materials. These materials can be extremely difficult to separate from the valuable materials miners are after. Perhaps the most efficient way of separating these materials is through magnetic separation. Magnetic separation is the process of using magnetic force to remove metallic or ferrous materials from a mixture. Magnetic separation machines consist of a vibratory feeding mechanism, an upper and lower belt and a magnet.

What makes magnetic materials; magnetic? What are magnetic and non-magnetic materials? Let us find out! Materials can be classified based on the response towards a magnet. Let us perform an activity to find how different materials respond towards a magnet. Collect different materials from your surroundings like Iron nail, brass screw, aluminium foil, plastic comb, coin, sewing needle, copper wire, aluminium foil, glass marble, eraser, stainless steel spoon, plastic ruler, pencil etc.

Magnetic attraction can be used to separate objects made of Name the method of separation that uses this set of Separation Techniques Worksheet Get Price; magnetic separation Magnetic separation is based on the differing degrees of attraction exerted on various minerals by magnetic Magnetic Separation Method. Take some iron filings in a china dish. Add some sugar to it.

We have now looked at a number of ways in which matter can be grouped, such as into metals, semi-metals and non-metals; electrical conductors and insulators, and thermal conductors and insulators. One way in which we can further group metals, is to divide them into those that are magnetic and those that are non-magnetic. Magnetism is a force that certain kinds of objects, which are called 'magnetic' objects, can exert on each other without physically touching.

Separating iron filings, salt and sand is one of the most interesting experiments that can be undertaken by students investigating the principles of separation of materials. In this topic, you will be taken through the experiment and the theory used. Separation theory Generally, materials are separated according to differences in their physical properties. During the separation process, it is important not to chemically change any of the parts of the mixture if possible. This avoids costly chemical processes and loss of material. It is best to try to separate one component at a time, which means that this experiment can be expected to have at least three stages, corresponding to the removal of each component from the mixture. Physical properties In this experiment, the three constituent materials in the mixture are solids with significantly different physical properties, which makes separation easier.

## Magnetic Separation in the Mining Industry

Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. This technique is useful for not all, but few minerals such as ferromagnetic materials strongly affected by magnetic fields and paramagnetic materials that are less affected but the effect is still noticeable. A large diversity of mechanical are used to separate magnetic materials. Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate e. Michael Faraday discovered that when a substance is put in a magnetic environment, the intensity of the environment is modified by it. The table below shows the common ferromagnetic and paramagnetic minerals as well as the field intensity that is required in order to separate those minerals.

A bar magnet is an object made of certain materials which can attract metals like be applied in the laboratory, e.g. to a mixture of iron filings and sulphur.
