What is the process of separating minerals?

you have a sand-oil mixture consisting of fine gold,quartz, halite or rock salt and calcite. knowing the physical properties of these minerals, create a flow chart or describe the process on how you are going to separate them. write the items of equipment that you need to separate these minerals; Assume that the magma chamber has the following dimensions 10 kms long, 5 kms wide and 2 kms high. The follwing elements are also present – Si, Na, K, Fe, Mg, O, and Al. What minerals and rock types do you expect to crytallize? Let’s say that the magma was able to vent through the surface through a series of volcanic eruptions. What changes can you seein the composition viscosity and eruptions style of your volcanic flows? What would be the composition of the oldest and youngest volcanic flows?
