Detailed explanation-1: -Heterogeneous mixtures can be separated by handpicking, filtration and sieving.
Detailed explanation-2: -Complete answer: The mixtures that can generally be separated by filters are the mixture of solid in liquid, solid in gas and solid in solid.
Detailed explanation-3: -A sand and water mixture is run through a filter paper (a filter with very fine pores). Larger sand particles are trapped by the filter paper and separated from the water.
Detailed explanation-4: -A mixture of sand and water can be separated by the process of sedimentation and decantation.
Detailed explanation-5: -Heterogeneous mixtures can be separated into their respective constituents. For example, a mixture of mud and water can be separated through filtration process easily, because water being liquid will pass through the filter paper easily but the mud will not because of it being solid.
