Ores And Minerals

Ores And Minerals – Isolation of elements in Chemistry class 12th aims to teach the students about the various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, Platinum, etc are present in their original metallic forms in nature. Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environment. Most of the elements especially metals are present combined with other elements and these are called minerals.

An element may combine with a variety of other elements to make myriad minerals but out of them, only a few are viable sources of that metal. Such sources are called ores. Let’s have a brief look into some of the ores and minerals.

Extraction of Ores And Minerals

The process of extracting metal ores buried deep underground is called mining. The metal ores are found in the earth’s crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! Ores are very different from the finished metals that we see in buildings and bridges. They consist of the desired metal compound and the impurities and earthly substances called gangue. The extraction of metals and its isolation occurs over a few major steps:

  • Concentration of Ore
  • Isolation of metal from the concentrated Ore
  • Purification of the metal

Difference between Ores and Minerals

Here we have provided the major differences between Minerals and Ores.

Minerals Ores
All the naturally occurring substances of metals which are present in the earth’s crust are known as Minerals. Ores are usually used to extract metals economically. A large amount of metals are present.
All Minerals are not ores. All ores are minerals.
Minerals are native form in which metals exist. Ores are mineral deposits.
