Bloomery process | metallurgy | Britannica

Bloomery process, Process for iron ancient times, smelting involved creating a bed of redhot charcoal in a furnace to which iron ore mixed with more charcoal was added. The ore was chemically reduced (see oxidationreduction), but, because primitive furnaces could not reach the melting temperature of iron, the product was a spongy mass of pasty globules of metal intermingled with ...

This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine. Smelting with fluxes A flux is a substance which is added to the ore to make it melt more easily. The solid calcine is heated to 1200°C and melts.
