Smelting, Blasting & Crushing Mineral Ores
Smelting, blast furnace processing, and mechanical crushing wheels offer multiple avenues to refine the vast array of ore stones and raw mineral nuggets discovered across subterranean rock strata. Choosing the right thermal or mechanical process maximizes your yield of pure ingots, gemstones, and energetic dusts.
Direct Smelting and Blast Furnace Refining
Raw mineral nuggets and ore-bearing host rocks can be smelted in a standard furnace or accelerated through a blast furnace for double speed:
- Smelting one
Raw Copper Nugget yields one 
Copper Nugget, allowing nine nuggets to assemble into a standard copper ingot. - Refining one
Raw Iron Nugget in a blast furnace produces one 
Iron Nugget. - Smelting one
Raw Gold Nugget yields one 
Gold Nugget. - Smelting one
Raw Bismuth Nugget produces one 
Bismuth Nugget. - Heavy dense minerals such as
Raw Magnetite smelt directly into a full 
Iron Ingot.
Intact ore blocks quarried from varied geological matrixes can also be smelted directly into single refined products:
- Smelting
Andesite Coal Ore produces one 
Coal. - Smelting
Andesite Copper Ore yields one 
Copper Ingot. - Smelting
Andesite Iron Ore yields one Iron Ingot. - Smelting
Andesite Gold Ore yields one 
Gold Ingot. - Smelting
Andesite Redstone Ore produces one 
Redstone Dust. - Smelting
Andesite Emerald Ore yields one 
Emerald. - Smelting
Andesite Lapis Lazuli Ore yields one 
Lapis Lazuli. - Smelting deep
Smooth Basalt Diamond Ore produces one 
Diamond.
Specialty thermal recipes also provide helpful utility: smelting one 
Water Bucket evaporates the fluid completely to leave one 
Salt Bucket, while blasting a common 
Carrot or smelting a 
Baked Potato carbonizes the food into a compact 
Charcoal Briquette fuel lump.
Mechanical Crushing Wheel Multipliers
Rather than burning ore blocks in furnaces for a single gem, feeding ore rocks into mechanical crushing wheels fractures the surrounding stone and releases uncut rough gems in higher quantities:
- Crushing standard
Redstone Ore, Andesite Redstone Ore, or 
Diorite Redstone Ore produces two 
Rough Cinnabar stones. - Denser variants including
Deepslate Redstone Ore, 
Granite Redstone Ore, 
Calcite Redstone Ore, and 
Tuff Redstone Ore fracture into three Rough Cinnabar stones. - Crushing
Diamond Ore, 
Diorite Diamond Ore, or 
Granite Diamond Ore releases one 
Rough Diamond, whereas dense 
Deepslate Diamond Ore, 
Andesite Diamond Ore, Smooth Basalt Diamond Ore, and 
Tuff Diamond Ore break apart into two Rough Diamond gems. - Processing
Emerald Ore, Andesite Emerald Ore, 
Diorite Emerald Ore, or 
Granite Emerald Ore yields one 
Rough Emerald, but exceptionally rich 
Tuff Emerald Ore shatters into eight Rough Emerald gems. - Lapis ores yield between two and four
Rough Lazurite stones, which can be further crushed individually to yield six 
Blue Dye items per stone. - Finally, passing
Nether Gold Ore through crushing wheels shatters the netherrack matrix to release 18 Raw Gold Nugget pieces.
