A mixture is a combination of two or more components (elements and/or compounds) that do not interact chemically, and most often retain their individual properties. Components of mixtures could be separated by simple physical means. Tea leaves and iron filings constitute a mixture; the components can be separated just by holding a magnet close enough, so that the iron filings are attracted to it, leaving the leaves beneath. Air that we breathe is mostly nitrogen and oxygen mixed together.

A teaspoonful of table salt added to a glass of water produces a solution. Depending upon the particle size, the mixing may give rise to a solution, a colloid or a precipitate. Thus, liquid fat dissolved in water produces a colloid called milk. The fatty liquid layer may get separated from the aqueous layer. Kerosene in water constitutes such a mixture.

Depending upon the number of phases obtained after mixing, mixtures may be homogeneous, or heterogeneous. When only one phase results after mixing, it is called a homogeneous mixture. Salt solution or gaseous mixtures are examples. When more than one phase is present in the mixture, it is a heterogeneous mixture. Iron filings with tea leaves, or milk or kerosene in water are examples of heterogeneous mixtures.

A mixture is made of at least two substances that are not chemically combined.  That means that each substance keeps its identity.  Mixtures can be separated by physical means as well.  A bucket of sandy water for instance is a mixture.  You could pour the sandy water through a filter and separate the sand from the water. That's what meant by physical means.  The substances can also be mixed together in any amount.  It doesn't have to be a 50/50 split.  Granite is an example of a mixture.  It is made of quartz, mica, and feldspar.  Pizza toppings represent a mixture as well or hamburger toppings.  

All of the examples I have given so far are heterogeneous mixtures meaning that that are not "well mixed."  You can see each of the substances.  A homogeneous mixture is going to be one that is very well mixed.  This means that you can't see the separate bits of the mixture.  It looks uniform throughout.  Milk is a good example.  As is stainless steel (iron and chromium).

A mixture is defined as at least two substances that mixed together and can be separated through process of separation. Some great examples of mixtures would be

-A can of peaches: this is because the preservatives can be separated from the peaches through a strainer.

-Sand and water since sand can be separated form water

-salt water: since salt can be separated from water through evaporation.

Mixtures are pretty much two or more substances that when combined, make a solution. This solution consists normally of a solvent (solvents) and a solute. Also, the substances in the mixture, once combined, will stay combined till there is some process that comes and separates the two substances. So this excludes oil and water, since the two will never mix. However, you can most surely mix together salt and water, or sugar and water. 

There are more examples given in the link below.

Mixture is a combination of two or more substances with variable compositions, that even after combining maintain their original properties, and can be separated using physical methods like distillation and filtration.

Some examples of mixtures are as follows:-

  • Water and Oil
  • Sugar and water
  • Sugar and salt
  • Cereal and milk
  • Water and sand
  • Air (Oxygen+nitrogen+other gases)
  • Sand and water
  • Atom (nucleus + electrons)
