Answer:Please see answers in the explanation column
Explanation:
In a mixture of salt, sand, iron fillings, and large rocks in a big bucket.
The process of separation is as follows:
Ist step ---
Use of magnet : Because Irons are attracted to magnet, Introducing a magnet to the mixture will cause the iron fillings to cling to the magnet leaving the other constituents behind
2nd Step
we eliminate the large rocks by carefully Sorting or picking them out since they are large and visible or we use a MESH or Sieve and carry out the separation by pouring the rock, salt and sand mixture on top of the mesh with continuous shaking so as to filter the smaller particles,The smaller particles will pass through the mesh while the bigger rocks remains on top.
3rd Step
We are left with the salt and sand. we will then introduce water to mix the salt and sand. salt dissolves completely in water while the sand settles as the bottom of the container. We can then separate the sand by decantation and then filtration to remove any left over sand.
4th step
Evaporation is then carried out on the salt solution to separate the salt from water.
