What Makes A Rock An Ore?

Ore is natural rock or sediment that contains one or more valuable minerals typically containing metals that can be mined treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined often via smelting to extract the valuable metals or minerals.

What is required for rocks to be considered ores?

How do you identify ores?

When identifying a mineral you must:
  1. Look at it closely on all visible sides to see how it reflects light.
  2. Test its hardness.
  3. Identify its cleavage or fracture.
  4. Name its luster.
  5. Evaluate any other physical properties necessary to determine the mineral’s identity.

Are all minerals ores?

Ores are defined as the minerals that contain higher concentrations of certain elements which are most of the time metal. … All ores are minerals and metals can be extracted commercially. But all minerals are not ores because some of the minerals have unwanted substances.

How do ores occur in nature?

Metals are often extracted from the Earth by means of mining resulting in ores that are relatively rich sources of the requisite elements. … When a metal ore is an ionic compound of that metal and a non-metal the ore must usually be smelted (or heated with a reducing agent) to extract the pure metal.
