Question

Separation of particles of various sizes, shapes, and densities by allowing them to settle in a fluid is called:

• A. classification
• B. froth flotation
• C. thickening
• D. sedimentation

Hint:

Sedimentation is commonly used in separating particles based on their density by allowing them to settle in a fluid.

Answer 1

The Correct Option is D

Step 1: Understanding the process.
Sedimentation is the process of separating particles from a fluid by allowing them to settle under gravity. It is commonly used in industries like water treatment and mineral processing.

Step 2: Explanation of options.
- (D) Sedimentation is the correct process for separating particles based on their size, shape, and density. - (A) Classification is the process of sorting particles by size. - (B) Froth flotation is used for separating hydrophobic particles. - (C) Thickening is used to increase the concentration of solids in a slurry.

Final Answer: \[ \boxed{\text{D) sedimentation}} \]
