Learning Objectives: Identify and explain the principles behind a particular separation technique that is used in daily life and in industry. Identify an appropriate separation technique to separate a mixture based on the physical properties of the components of the mixture. These properties include solubility, density, melting and boiling points, thermal stability, magnetic properties and…
Sedimentation is a separation technique in which heavier impurities present in water settle down at the bottom after some time if you keep the mixture still at one place. The heavier constituent which get settled at the bottom is known as sediment and the water above it is known as supernatant.

2. DEFINITION: Separation techniques are those techniques that can be used to separate two different states of matter such as liquids and solids. Separation processes or a separation method or simply a separation is methodology to attain any mass transfer phenomenon that convert a mixture of substances into two or more distinct product mixtures.
Dry, free-flowing, granular product: If the particles are small and free-flowing, a grate magnet may provide the best opportunity for the ferrous contamination to contact a magnet directly. Grates do the best job with vertical product flows, while plate magnets work well if the material is cascading down a chute.
The mechanism involves taking advantage of the unequal density of the particles in the mixture. Oil and water can be easily separated using this technique. Magnetic Separation. When one substance in the mixture has some magnetic properties then this method is quite useful. Strong magnets are commonly used to separate magnetic elements.
Maxima Magnetic Bar separator is used for separating ferrous contaminants from free flowing material, which are good choice of bar separator . All the ferrous particles like bolts, nuts, chips, damaging tramp iron can be caught and held effectively. So it provides a good solution of material magnetic separation and equipment protection.
Sieving is a suitable separation method when the pieces to be separated are sized differently. Filtration is a good method for separating an undissolved solid from a liquid. Components with different magnetic properties can be separated using magnetic separation. Evaporation is a suitable separation method for removing a liquid from a solid.
Magnetic Separation We make permanent Magnetic Separation Equipment for any application, suitable for almost any industry.; Metal Detection Designed to monitor gravity-fed products, pneumatically conveyed materials on belts, & liquids and slurries in pipes.; Material Handling Equipment A large lineup of material handling equipment for the Recycling, Metal Stamping, Plastics and Food industries.
Magnetic Separation This method of separation is exemplified by the separation of iron filings. A mixture with iron filings as one of the components can be separated using a magnet to attract the iron particles away from the mixture. Fig 4: Chromatography Chromatography Chromatography is an advanced technique of separation in which individual
Magnetic drum separators are important magnetic separators that removes ferrous metal from dry bulk products in free-flowing processing systems. They are self cleaning unit consisting of drums and housing normally of stainless steel. The magnetic drum separators are available both in single or double drum configuration.
Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.
The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.
The efficiency of the separation process depends on 1. flow rate of slurry. 2. percent of magnetic solids in the feed. 3. slurry percent solids. 4. particle size. 5. uniformity of distribution of slurry over the drum surface. 6. radial position of magnets within the drum and the field strength.

Magnetic separation of particulate mixtures is highly developed and long-practiced. The technique may be practiced as a wet process, such as in a water slurry, or may be used to separate a dry particulate mixture. Magnetic separation is cheap, highly selective, efficient and lends itself to both small scale and large volume uses.
The magnetic separation process often leads to a middling fraction which require either disposal or recycling back to the feed stream. Magnetic separation using rollers have other limitations in processing fines. The fine particles, even non-magnetic tend to form coatings on the roller, rendering the separation process ineffective.
