• Analysis

11. Separating mixture by using a magnet can be used to separate mixtures
when one of its components is magnetic like iron filings and small nails.
Mechanical separation involves the use of tools such as magnets, forceps,
and sieves to separate solids that are mixed. The magnetic material is
attracted by the magnet, leaving the non-magnetic material behind. The use
of magnet to separate metallic materials is useful in many ways. Here are
some of the benefits of separating mixtures using magnets.
 Magnets are used in food processing industries for separating small
metallic pieces from flour, grains etc. to avoid metallic contamination
 Magnets are used to separate mixture of iron filling and Sulphur
 Magnets are used to separate iron nails from sawdust.
 They are also used to sort out magnetic and non-magnetic materials
from scraps and junks.

25. Another way of separating mixtures is through evaporation. Applying heat
will cause the liquid in a mixture to evaporate leaving the other component/
substance behind. Evaporation is a technique used to separate homogeneous
mixtures where there is one or more dissolved substance. The method drives off
the liquid components from the solid components. The process typically
involves heating the mixture until liquid evaporates into water vapor. There are
many ways by which evaporation take place in our community or at home which
are beneficial to us.
 Salt Making
 Sugar Refinement
-Salt and sugar crystals obtained either from a natural process or from an
industrial process, evaporation is used
 Evaporation is used in producing patis (fish sauce).
 The cooling of hot milk or tea is caused by the evaporation of hot molecules
on the surface; thus, it becomes just enough for drinking.
• B. Abstraction

26.  When cooking rice or heating foods, evaporation takes place that caused
changes in the materials.
 The evaporation process is used in food processing industries to process
milk, pasta, and other concentrates.
 Another field in which evaporators are widely used is waste management.
Waste management providers rely on them to treat effluents, or wastewater,
from various plants, including distilleries, grain mills, textile plants, chemical
reactors, and storage tanks.
 Evaporators are also used in oil fields to separate water and various other
compounds from crude oil.

• Analysis

42. • Abstraction
Decantation is the process of separation of liquid from solid and other
immiscible (non-mixing) liquids, by removing the liquid layer at the top
from the layer of solid or liquid below. In the process of decantation, the
mixture is left undisturbed. When the components are separated, the less
dense substance could be removed by scooping using a spoon or it can
be removed by slowly pouring out the less-dense substance. The
following are the activities in the community where decantation as a
process of separating mixture is beneficial to us.
In school/experiments
 Separation of oil and water
 Separation of gasoline/ kerosene and water
 Separation of muddy water
 Separation of metallic materials from sand and silt.

Another way of separating mixtures is through Centrifugation. It is a way of
speeding up the process of sedimentation. A centrifuge, found in a laboratory,
consists of many test tubes spinning at a high speed which inevitably forces the
insoluble substance to the bottom quicker. A washing machine is a good example
of this process. It spins quickly and water flies out through the holes in the sides
and the clothes stay in the washing machine. Here some of the benefits of
separating mixtures through centrifugation.
Separation of blood components
Separation of suspended solids from solutions, example separation of clay
particles from water
Skimmed milk can be obtained from whole milk with the help of the process
centrifugation
Getting sugar from sugarcane juice/ sugar production
Stabilization and clarification of wine
The centrifugation of contaminated water allows to extract dense substances
inside
Production of beverages, juices, coffee, tea, beer, soy milk, cheese
