WHAT IS IRON SMELTING? Smelting is a process of applying heat to an ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical- reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures as the chemical potential energy of the bonds in carbon dioxide (CO2) is lower than the bonds in the ore. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the carbon monoxide reacts with the ore (e.g. Fe2O3) and removes one of its oxygen atoms, releasing carbon dioxide (CO2). After successive interactions with carbon monoxide, all of the oxygen in the ore will be removed, leaving the raw metal element (e.g. Fe). As most ores are impure, it is often necessary to use flux, such as limestone (or dolomite), to remove the accompanying rock gangue as slag. This calcination reaction also frequently emits carbon dioxide. Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. https://en.wikipedia.org/wiki/Smelting |

ednut1:No, they did not INVENT it independently. Iron smelting was an invention, not a discovery. Ancient Africans took this knowledge to other continents. Because AFRICA is the Cradle of Civilization. Do you know that the worlds oldest PAINT FACTORY was discovered in South Africa, and was dated to an incredible 100,000 years old? That is 95,000 years before our oldest written records! . . Ancient Paint Factory Unearthed in South Africa BBC news The kits used by humans 100,000 years ago to make paint have been found at the famous archaeological site of Blombos Cave in South Africa. The hoard includes red and yellow pigments, shell containers, and the grinding cobbles and bone spatulas to work up a paste - everything an ancient artist might need in their workshop. This extraordinary discovery is reported in the journal Science. It is proof, say researchers, of our early ancestors' complexity of thought. "This is significant because it is pushing back the boundaries of our understanding of when Homo sapiens - people like us - first became modern," said Prof Christopher Henshilwood from the University of the Witwatersrand, Johannesburg. "These finds indicate that humans were certainly thinking in a modern way, in a way that is cognitively advanced, at least 100,000 years ago," he told BBC News. ....The finds include abalone shells with ochre residues inside. There are tools made of quartzite that were presumably employed to hammer and grind ochre into a powder in the shells. And there is evidence that charcoal and oil from seal bones were being added to the mix. It seems bone implements were also being used to turn and lift the paint pastes. The mere fact though that paints are being manufactured in a systematic way is indicative of a level of advanced thinking. It would have required a high degree of planning to bring together all of the elements of the kits; and if art really was the purpose, it suggests the cave dwellers of Blombos were capable of symbolic thought - the ability to let one thing represent another in the mind. https://www.bbc.co.uk/news/science-environment-15257259 |

ANCIENT NIGERIANS INVENTED IRON SMELTING. WITHOUT THIS NIGERIAN INVENTION, THE ENTIRE WORLD WOULD STILL BE STUCK IN THE STONE AGE, AND LIVING IN CAVES TODAY. World's Oldest Iron Smelting Site, dated 2,000 BCE, Discovered in Lejja, South East Nigeria https://dailytrust.com/wp-content/uploads/2018/07/2018_7large_A_portion_of_the_piles_of_ancient_stones_at_the_village_square.jpg https://upload.wikimedia.org/wikipedia/commons/b/b2/Lejja_iron_slags.png https://pbs.twimg.com/media/DyPvyatX4AAEEjO.jpg In a village square in Lejja, located about 15 kilometers south of the university town of Nsukka in southeastern Nigeria, lies what appears to be the oldest iron-smelting site in the the world. Arranged in crescent shapes with mounds in the middle across a wide sitting area at Otobo Ejuona, as the arena is known, are hundreds of bits of smelting debris, or slags, recently carbon-dated to about 2000 BCE by a team of archaeologists and other experts from the University of Nigeria, Nsukka and Oxford University in the United Kingdom. The information yielded by the slags upsets the status quo as far as the global story of ironworking is concerned. For long conventional academic wisdom had it that the iron age started in southwest Asia in 1500 BC and spread to the rest of the world, including Africa, from there. Evidence of iron smelting in Africa that is at least 500 years older stands this conventional wisdom on its head. Why does iron matter? Iron matters because it changed the course of human civilization. Armed with iron, humans, the tool makers, finally found their vocation. They quickly transformed from hunter-gatherers to accomplished farmers armed with iron implements with which they cleared the bush and tilled the soil. They built weapons – spears, knives, guns – with which they went to war, conquered territories and built empires and began the march of civilization to where it is today. It was the precursor revolution that inspired all other revolutions that followed it. With the determination of the age of the Lejja site, the claim that has subsisted among many Western academics that there was no independent development of iron working in Africa is effectively rebutted. Otobo Ejuona Slags are the waste byproduct produced when iron is heated in order to remove it from its stone ore. Tens of hundreds of these granite-like objects, some weighing as much as 60 kilograms, are arranged in patterns by people of whom the present occupants of Lejja have no memory. However, for them the site has acquired religious significance and become central to the people’s existence, housing the community shrine and meeting place of the masquerade cult, as well as serving as a general meeting place. Other smelting sites have been discovered in nearby places like Opi (dated 750 BC) , Umundu and Obimo, but none matched the antiquity of the Lejja site. The aesthetics of Otobo Ejuona The slags, from which iron ore had been extracted, were transported to this site sometime in antiquity, and arranged in the patterns they were found. The most prominent pattern is the crescent shape made with the slags on the higher ground of the village square, which is faced by a mound of slags heaped together. Other arrangements then spread out with the gentle slope of the square. In the middle there’s a raised mound of earth, around which slags are arranged. Other semi-circular heaps are also displayed around the square. To the right of the square, there’s a conical-shaped small building, the traditional masquerade’s house. At the base are also placed several slags. Archaeologists and other scholars see both an aesthetic and an astronomical purpose in the placement of the slags. For instance, the half-circular arrangement of the slags and the placement of a mound in the middle is thought to represent the intermittent visual nearness between the crescent moon and the planet Venus. [Our ancestors were masters of astrology] Therefore, the placement of the slags had a ritual symbolism attached to it and was never done randomly. While the present-day inhabitants of Lejja don’t have much information about their creation, they have keyed into its ritual significance, celebrating and receding it as something intrinsically linked to their existence and well being. https://thingsnigeria.com/2018/02/14/lejja-the-worlds-oldest-iron-smelting-site-in-nigeria/ 2 Likes |

Nigeria’s annual budget is 40 billion dollars for 220 million people, so it takes time to fix stuff. It is stupid and dumb to demand the same level of infrastructure as obtains in Britain. They invaded and colonised your country and other nations for a whole century and sold your natural resources, sending the proceeds to London. That’s why they are so rich today. |

Nigeria also holds one of the largest economies in Africa and is capable of value-adding industries associated with the lithium supply chainThis is the main difference between Nigeria and some of these African countries like Niger and co. Nigeria has the capacity to leverage these resources IN-HOUSE. Process them and build anything we want. I'm very glad Nigerian and African leaders have said that this LITHIUM of a thing will not be like previous raw materials that were just shipped out raw for a pittance. That era is gone and gone for good. The other day, Ugandan President Museveni said that some European investors had visited him in his office, and said they wanted to mine Ugandan lithium. He asked them why. They said because they wanted to use it to build nuclear power plants, to increase their power generation. He asked them if they'd ever seen the Access to Electricity statistics for Uganda, vis-a-vis their country. They said no. He said ok, that they should go and read it, and get back to him, so that they could discuss how they could partner to use the lithium to increase power generation in UGANDA FIRST, before he can allow them to buy any extra they have left. He said they left and never returned. These people? If you don't use your sense with them, they will finish you. 157 Likes 11 Shares |
