What is the relationship between ores and gems?
is that gem is a precious stone, usually of substantial monetary value or prized for its beauty or shine while ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which — at the time of the rock’s evaluation and proposal for extraction — are able to be separated from its …
What is the relationship between metals and minerals?
Minerals are solid, naturally occurring inorganic substances found in the Earth’s crust. They have a unique chemical composition and crystal structure. Metals are elementary substances, such as gold, silver and copper. They are crystalline when solid and naturally occur in minerals.
What makes a mineral A ore?
An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically.

What is difference between minerals and ore?
Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. You need minerals to make rocks, but you don’t need rocks to make minerals.
What is the difference between an ore and a metal?
Ore- A mineral occurring in sufficient quantity and containing enough metal to permit its recovery and extraction at a profit. Metal- An alloy of two or more metallic elements. Therefore, Rocks have minerals, which in large concentration are called ores and these are mined for metals!
