Thank you for the opportunity to help you with your question!
you could use the method "separation by density",which is were heterogeneous mixtures are separated on the basis of particle density.At medical places they use a machine called centrifuge when you get blood pulled. More dense materials move to the bottom and less dense plasma moves to the top.
Please let me know if you need any clarification. I'm always happy to answer your questions.
