The first step in turning ore into useful minerals starts with making the ore smaller by crushing and grinding it under high pressure. Machines called jaw crushers and gyratory crushers are super important for breaking the ore into smaller bits. These big, strong machines squish the ore to make it smaller.
Iron ore generates in three batches. The first batch attempts to generate 90 times per chunk in blobs of 0-13 [JE only] or 0-16 [BE only], from levels 80 to 384, being most common around level 232 and becoming less common toward either end of the range.The second batch attempts to generate 10 times per chunk in blobs of 0-13 [JE …
Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots.
