Decisive Battles In Levant, Fathi Habashi
Decisive Battles In Levant, Fathi Habashi
Fathi Habashi
The Levant has been a battle ground since ancient times. The Battle of Kadesh took place in 1274 BC showed the supremacy of iron in war, in the Battle of Yarmouk in 636 AD the Arabs entered the Middle East, in Hittin in 1187 Saladin defeated the Crusaders, in Ein Jalut in 1260 Baibars saved Egypt from destruction by the Mongol, in Marj Dabiq in 1516 the Ottomans opened the way to occupy Egypt and the Middle East, while in World War I General Allenby of the British Empire entered Jerusalem in 1917 thus marking the beginning of the end …
Hydrometallurgy In The Past Decades. A Personal View, Fathi Habashi
Hydrometallurgy In The Past Decades. A Personal View, Fathi Habashi
Fathi Habashi
In the 1940s hydromtallurgy benefitted a great deal from Manhattan Project in USA, then in the 1950s a new technology was introduced by Sherritt-Gordon Mines in association with the Mines Branch in Ottawa to treat ores with ammonia under pressure and to precipitate metals from solution by hydrogen under pressure. Since then hydrometallurgy has made great progress as evidenced by the number of conferences held to discuss this topic. A personal view of these developments with those involved is given.
Metallurgical Chemistry, Fathi Habashi
Metallurgical Chemistry, Fathi Habashi
Fathi Habashi
Metallurgical chemistry is the most ancient science of chemistry. It is related to the recovery of metals from ores and their refining. In its modern form, it involves separation of finely ground minerals by flotation, melting of ores, aqueous processing of ores, and the application of electric current to separate and purify metals from aqueous solution or from a fused salt. Metallurgical chemistry is closely related to the chemical industry.
Hydrometallurgy Of Phosphate Rock And The Recovery Of Uranium, Fathi Habashi
Hydrometallurgy Of Phosphate Rock And The Recovery Of Uranium, Fathi Habashi
Fathi Habashi
Phosphate rock of sedimentary origin contains on the average 0.01 % uranium. Since large tonnage of this rock is used annually to produce fertilizers, this represented an important potential source of uranium. Before the discovery of rich uranium deposits this source was developed on industrial scale. The production of phosphoric acid by sulfuric acid process is at present facing the problem of disposal of gypsum; about 1.5 tons of gypsum is produced per ton of rock processed. This material contains all the radium originally present in the rock which results from the radioactive decay of uranium. As a result, phospho-gypsum …
Sir Walter Raleigh And Tar Sands, Fathi Habashi
Sir Walter Raleigh And Tar Sands, Fathi Habashi
Fathi Habashi
Petroleum is sometimes ejected from underground to form lakes contaminated with rocks. The volatile components evaporate with time leaving behind a solid mixture known as asphalt or tar sands. Lake Asphalt in Trinidad contains about 40% bitumen. Sir Walter Raleigh (ca 1554 –1618) sailed to Trinidad in search of El Dorado but he discovered the lake instead.

De Re Metallica. A Metallurgist On The Move, Fathi Habashi
De Re Metallica. A Metallurgist On The Move, Fathi Habashi
Fathi Habashi
De Re Metallica is a diary of the trips the author has undertaken during his professional career. He visited many industries, universities, research centers, and museums, and participated in many conferences. The book in 5 520 pages and many coloured photos therefore reflects the state of extractive metallurgy since he left his home country Egypt and went to study in Vienna then emigrated to Canada.
