How can you seperate a mixture of sodium chloride, sand, iron filings, and copper shot and......?

Pick out copper shot by hand. Take out iron filings using a magnet. To get the salt out put the remaining mixture in a paper filter and run hot water through it. This will melt all the salt and run it through the filter leaving the sand. Then put the salt water in a beaker and warm with a bunsen burner to evaporate the water.
