This document discusses different methods for separating mixtures into their component parts. It describes simple separation methods like hand picking, threshing, sieving, and winnowing. More complex laboratory methods are also outlined, including sedimentation, decantation, filtration, evaporation, and condensation. Each separation method is used for a specific purpose, such as removing unwanted components, impurities, or harmful substances. The separated components are then used or disposed of accordingly.

1. Separation of Mixtures
Shia Mentors, Govandi

2. What is Mixture?

3. Why do we separate mixtures?
Separation
Process
Purpose for which we do
the separation
What do we do with the
separated components?
1) Separate
stones from rice
a) To separate two different,
but useful components.
i) We throw away the soild
component.
2) Churning milk
to obtain butter
b) To remove non-useful
components.
ii) We throw away the
impurities.
3) Separate tea
Leaves
c) To remove impurities or
harmful components
iii) We use both the
components
Short Exercise
Match each process with its purpose and
the way separated components are used

Complex Methods of Separating substances
• Sedimentation:
When the heavier component in a mixture
settles after water is added to it, the process is
called sedimentation
• Decantation
When the water is removed avoiding the
sediment, the process is called Decantation
• Filtration
Process of separation using some filter like
strainer is called as Filtration

6. Methods of Separation
Complex Methods of Separating substances
• Evaporation:
The process of conversion of water into its vapour
is called evaporation
• Condensation:
The process of conversion of water vapour into its
liquid form is called condensation
