You will need a pickaxe or mining hammer to mine ores.
A regular hammer can also break stone type blocks quickly, but will not result in dropped ores. It can still be useful for extracting stone blocks however.
Item: #minecraft:pickaxes
Breaking an ore block with a pickaxe will yield raw ores (poor, normal, or rich), as well as some stone dust. These are not worth much mB each and you will need multiple to make a single ingot, however some other minerals are only useable in this state, such as coal.
Item: #forge:tools/mining_hammers
These are basically a pickaxe with a 3x3 range, and will yield raw ores as well. Also good for quarrying stone!
Holding sneak will only break a single block at a time.
Processing ores will result in much greater amounts of usable metal. The first step is to use a Quern to crush the raw ore. This step can be automated in the future with improved machines such as the Millstone, Crushing Wheel, Macerator, and Forge Hammer.
To make your crushed ores melt into even more mB, first place them in a crafting grid along with a Hammer. This will produce Impure Dust. To purify the dust, throw it in water or Right Click a Cauldron filled with water.
