How to Identify Black Minerals ThoughtCo

Jul 29, 2019 · Pure black minerals are less common than other types of minerals and can sometimes be difficult to recognize if you don't know what to look for. However, by carefully observing such things as grain, color, and texture and studying their most notable characteristics—including luster and hardness as measured on the Mohs Scale—you should soon

Ore Facts for Kids

An ore is a mineral which has a metal inside it. Ores are usually extracted by being mined. They can sometimes be found on the Earth's surface. The metal in ore is often valuable. There are different ways to get the metal out of the ore. Iron ore, for example, is smelted in a blast furnace. Images.
