In Minecraft, copper has several uses, including construction, crafting lightning rods and spyglasses, and replacing certain types of blocks. Here are some of the ways you can use copper in Minecraft:

• Copper Ingots: Copper ore can be smelted into copper ingots, which are used to craft other copper items.

• Construction and Decoration: Copper blocks can be used for building and decoration. They have a unique oxidization mechanic that causes them to change color over time, resulting in different colored variants.

• Lightning Rods: Copper can be used to craft lightning rods, which protect structures from lightning strikes.

• Spyglasses: Copper ingots can be used to craft spyglasses, which allow players to zoom in and focus on a specific point in their field of view.

• Replacing Blocks: Copper ore can be used to replace certain types of blocks, including stone, granite, diorite, andesite, tuff, and deepslate.

To use copper in Minecraft, you will need to find raw copper ore underground, which is most commonly found underneath beaches. You will need a stone pickaxe or better to mine it. Breaking a block of copper ore gives you a few units of raw copper, which can be smelted into copper ingots.
