EdomEdom (ˈiːdəm; Edomite: 𐤀𐤃𐤌 ; אֱדוֹם , lit.: "red"; Akkadian: 𒌑𒁺𒈪 , 𒌑𒁺𒈬 ; Ancient Egyptian: ) was an ancient kingdom in Transjordan, located between Moab to the northeast, the Arabah to the west, and the Arabian Desert to the south and east. Most of its former territory is now divided between present-day southern Israel and Jordan. Edom appears in written sources relating to the late Bronze Age and to the Iron Age in the Levant. Edomites are related in several ancient sources including the Tanakh, a list of the Egyptian pharaoh Seti I from c.
PrehistoryPrehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5,000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century.
MidianMidian (ˈmɪdiən; מִדְיָן Miḏyān; Madyan; Μαδιάμ, Madiam) is a geographical region in Western Asia mentioned in the Hebrew Bible and Quran. William G. Dever states that biblical Midian was in the "northwest Arabian Peninsula, on the east shore of the Gulf of Aqaba on the Red Sea", an area which contained at least fourteen inhabited sites during the Late Bronze and early Iron Ages. According to the Book of Genesis, the Midianites were the descendants of Midian, who was a son of Abraham and his wife Keturah: "Abraham took a wife, and her name was Keturah.
IsraelIsrael (ˈɪzri.əl,_-reɪ-; יִשְׂרָאֵל Yīsrāʾēl jisʁaˈʔel; إِسْرَائِيل ʾIsrāʾīl), officially the State of Israel (מְדִינַת יִשְׂרָאֵל Medīnat Yīsrāʾēl mediˈnat jisʁaˈʔel; دَوْلَة إِسْرَائِيل Dawlat Isrāʾīl), is a country in West Asia. It is bordered by Lebanon to the north, by Syria to the northeast, by Jordan to the east, by the Red Sea to the south, by Egypt to the southwest, by the Mediterranean Sea to the west, and by the Palestinian territories - the West Bank along the east and the Gaza Strip along the southwest.
SlagSlag is a by-product of smelting (pyrometallurgical) ores and recycled metals. Slag is mainly a mixture of metal oxides and silicon dioxide. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further categorized by their precursor and processing conditions (e.g.
SmeltingSmelting 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.
OreOre is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore.
CopperCopper is a chemical element with the symbol Cu (from cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
