Why all ores are minerals but all minerals are not ores?

It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.

Why alkalai metals are found as compounds?

Alkali metals, such as sodium and potassium, are highly reactive and tend to combine quickly with other elements in nature to form compounds. This is because they have only one valence electron, which they easily lose to achieve a stable electron configuration. Therefore, it is rare to find pure alkali metals in their elemental form in nature.
