A gold bar

Metallic mineral deposits can contain materials such as, lead, zinc, iron, gold, silver, and even indium. Non-metallic mineral deposits can contain minerals such as silicon, phosphorus, or sulfur. Being metallic resources these elements are melt able which gives them the ability to be melted and formed into items used for construction, and in older days non-metallic resources were used to make weapons. So the most major difference between metallic and non-metallic mineral resources is the fact that metallic mineral resources are pliable. If you compare iron and sulfur you may find a different use for both of them. Iron of course would be made into something as stated before, but sulfur is actually quite useful. Sulfur is used in matches, but is most popular for it’s for its use as a hardening component to rubber. Edit
