Meroe’s iron producers made use of the direct, or bloomery, smelting technology. Unlike the blast furnace technologies of today, bloomery ironmaking involves the reduction of iron oxides to particles of iron metal in the solid state.
Small, workable iron veins were discovered in many areas in the state, and small furnaces were set up at these spots for smelting the ore and manufacturing bar iron for the pioneer blacksmiths.

The iron block contained various amounts of slag and therefore it had to be heated and hammered thoroughly to get the slag squeezed out from the block. The block was cut into smaller pieces and forged to tools and weapons or commercial blooms.
A bloomery is a type of furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron.
The direct process involved the smelting of roasted ore in a crude clay or stone furnace (bloomery) and the forging of the resulting spongy mass into a bloom of wrought-iron. This process was introduced into britain circa 500 bc (thus the early iron age) and during the early part of the roman occupation the weald was the chief area of production.

In hisarna ironmaking process, iron ore is processed almost directly into liquid iron or hot metal. The process is based around a type of blast furnace called a cyclone converter furnace, which makes it possible to skip the process of manufacturing pig iron pellets that is necessary for the basic oxygen steelmaking process.
A bloomery is a type of furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron.

A bloomery was a cheaper, simpler way to produce iron than by using a blast furnace. Like contemporary blast furnaces, the bloomery used charcoal for fuel, but unlike the blast furnace the iron ore never reached a temperature high enough for it to melt. In the bloomery operation, charcoal and iron ore were ignited and air applied.
Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
