The main minerals found in the oceans are as follows: 

1. Mineral Oil: This is the most important resource found in oceans. About 40 % of the world’s mineral oil reserves are in the sea floor. Many countries of the world are obtaining oil from seas. In India also, mineral oil is being extracted at a depth of 2000 meters on the Mumbai Highway, 150 km. away from the coast.

2. Phosphate: Unorganized sediment deposit consisting of minerals is called Phosphate. It is usually found in the form of lumps in the oceans.

3. Manganese: Nickel and copper are obtained from its lumps as they are obtained from land resources. It is found in the maximum amount in the Pacific Ocean.

4. Salt: Salt obtained from the seas is an important mineral. Oceanic water is saline. In this, the amount of dissolved salts is 3.5 %. About 78 % of the total salts include sodium chloride from which the salt for food is obtained by the process of evaporation. Salt worth 200 million dollars is produced in the world every year.

Other Minerals: In the other minerals, sand, gravel, gold, platinum, tin, magnetite, iron, tungsten, thorium etc. are the major ones.
