Minerals in a rock can be separated by putting the minerals in one section and the and the other things in the rock will be in a other section.

Thanks Jayden, but how did we separate the mineral salt from the rest of the mock rock? How did we identify the mineral?

You can separate minerals by taking an aluminium nail and hacking the rock apart and separating the minerals and then trying to find the minerals properties to identify them. You use an aluminum nail, a softer metal, because if it scratches the mineral, it means the mineral has a softer hardness (less than 3.5 on the Mohs scale)

In class we separated the rock from the water with a seringe. In science lab we separated the rock with an aluminum nail. We also separated the pieces of rock into groups of the properties.

The minerals in rock can be separated by using any aluminum object. In the science lab we used an aluminum nail to break apart the mock rock. I'm guessing that you could use anything that is harder than the rock to break it apart because that object would be able to crack open the rock.

Scratch with a fingernail, nail, or tile. Putting in a bag, and shaking, or banging with a hammer on the floor.
