It is possible to filter mud out of water.
it is a physical change because the appearance just changed.
Allow the mixture to sit until the oil and water have separated. Then pour off the oil.
What property of these metals would allow such a separation?
Pour it into a shallow dish and allow the water to evaporate away, which will leave sugar crystals behind.
Size and shape. However, chemical properties are usually more important.

Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.

This is possible because components of a mixture haven't chemical bonds between them.
first, put the mixture in water . salt will dissolve and then allow chalk powder to settle down. Then try decantation.
Use a centrifuge. Magnetic separation will not work if they are brass nails.
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them. If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example. If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve) If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel). If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.
One method is to use a process called chromatography. This involves placing a sample of the mixture onto a piece of filter paper. The filter paper is then placed in a container of a liquid solvent such as water. The solvent travels up the paper, carrying the mixture with it. As the solvent travels up the paper, the different components in the mixture separate and move at different rates, allowing you to separate the starch and sugar.
