Difference between gravity separation and magnetic separation in 4 points.
Answers
MAGANETIC SAPARATION
1.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 material with those that are magnetic. ... This can create a magnetic concentrate (e.g. an ore concentrate).
2.Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. Magnetic separation is also useful in mining iron as it is attracted to a magnet.
3.Magnetic separation is a method of waste management where magnets are used to separate metal from refuse. This is most common in single and mixed streams of recycling as the materials are collected together and separated before processing.
4.Mixtures containing substances that are attracted by magnets can be separated using a magnet. We can separate iron from a mixture of sand and iron, as only the iron is attracted to the magnet.
GRAVITY SAPRATION
1.Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight.
2.They can be used to separate and standardize coffee beans, cocoa beans, peanuts, corn, peas, rice, wheat, sesame and other food grains. The gravity separator separates products of same size but with difference in specific weight.
3.Gravity separation process is used for the concentration of haematite. Gravity method is based on the difference between the densities of the ore particle and gangue. It is used for the concentration of denser ores from the water soluble and lighter impurities (gangue).
4.The fundamental engineering principle of gravity separation is the settling velocities of particles, and recognition of two types of settling in stormwater treatment: dynamic and quiescent. Settling velocity is affected by particle size, shape, and specific gravity and by water temperature.
