Question

Which among the following statement is correct?

विकल्प

• metals are extracted from mineral

• all minerals are ore

• all ores are minerals

• a mineral cannot be an ore

all ores are minerals

All ores are minerals but vice versa is not true. Because ores are the minerals from which metal can be profitably extracted. There are many minerals from which we cannot extract metals profitably, so cannot be considered as ores.
