Primary Metallurgy is the science of extraction of metals from ores & minerals. If there are more than one ways of extracting a metal from its ore or mineral, then the process which gives a more pure form of metal will belong to the category of primary metallurgy & the other processes will belong to the category of secondary metallurgy. e.g. in case of iron making the blast furnace process is a primary metallurgical process whereas other processes of iron making i.e sponge iron or HBI making will belong to yhe category of secondary metallurgy, I
1) Concenteration by gravity seperation 2) Roasting and Calcination 3) Smelting
history of metal metallurgy
Metallurgy is broadly divided into following branches : 1. Mechanical Metallurgy 2. Physical Metallurgy 3. Extractive Metallurgy These are the basic divisions and these branches are further divided into various sub categories.
The Bantu were experts in iron metallurgy.
The Bantu were experts in iron Metallurgy.
Knowledge of iron Metallurgy helped the Bantu to migrate throughout the continent of Africa.
No Iron Making Started In Egypt.

The effect of iron metallurgy in the Bantu society is that they made many weapons from smelting copper and bronze together and it provided a wide range of trade for the Bantu people.
