Answer:
I'm so sorry but it's so difficult
Answer:
K
Explanation:
Sieving-Sieving is a simple technique for separating particles of different sizes.
Use of magnet/magnetism-Magnetic separation is a method of waste management where magnets are used to separate metal from refuse.
Hand picking-The method of hand picking is used to separate undesirable substances such as small pieces of stones from wheat, rice and pulses.
Scooping-is the use of the scoop to separate one subtance from another.
Floatation-Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.
Simple Distillation-In a simple distillation, a homogeneous liquid mixture is boiled.
Chromatography-Chromatography is a process for separating components of a mixture.To get the process started, the mixture is dissolved in a substance called the mobile phase, which carries it through a second substance called the stationary phase.
