dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper.

The smelting process can be automated with hoppers on the top and bottom of the furnace. For larger smelting jobs, a third hopper on the side of the furnace can feed in fuel and, in case of lava being used as fuel, any empty buckets come out of the bottom hopper. This automatically feeds and empties the furnace so that different materials can be …

MARKS et al. 2 1962). The spongy lump of iron known as a 'bloom' that is produced using this furnace has to be subjected to a smithing process to consolidate the metal and remove as much residual slag as possible. Then the iron can be worked into shape by heating and hammering (Pleiner 2000; Dungworth 2014; Champion 2018). Research regarding bowl …

A blast furnace is a block that smelts ores, raw metals and metal armor and tools twice as quickly as a furnace but cannot smelt anything else. It also serves as an armorer's job site block. A blast furnace can be picked up using any pickaxe. If mined without a pickaxe, it does not drop. Blast furnaces drop their contents when broken. Blast furnaces can …

These are vertical furnaces with the charge added at the top and removed at the bottom, while gas is blown into the bottom and exits the top, as shown in Figure 1. The solid charge must consist of particles coarse enough that they will not be blown out of the furnace by the gas. An iron ore blast furnace is a typical example of a shaft furnace.
