|
How do you refine salt from rock salt
|
Mix rock salt with water so that the salt dissolves, filter out the sand, heat the remaining salt and water so that the water evaporates and the refined salt is left
|
|
|
Uses for rock salt and refined salt
|
Rock salt-de icing roads
Salt- flavouring foods |
|
|
What is rock salt
|
Mixture of salt (sodium chloride) and sand

Phytomining definition
|
Mining may leave behind bits of metal that can be recovered by using plants that take up the metal from the soil and build it up in their leaves, the plants are then harvested, dried and burned and the metals are collected
