Titanium processing | Technology, Methods, & Facts
Titanium ore was first discovered in 1791 in Cornish beach sands by an English clergyman, William Gregor. The actual identification of the oxide was made a few years later by a German chemist, M.H. Klaproth. Klaproth gave the metal constituent of this oxide the name titanium, after the Titans, the giants of Greek mythology.
The Extraction of Copper
Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.
How is Tungsten made: From Ore to High-Tech Metal
From Ore to Metal: Once tungsten ore is extracted, it undergoes a series of processes to transform from a raw material into a usable metal. It's like a metamorphosis, where the ore sheds its rough exterior to reveal the valuable tungsten inside. ... Tungsten is both mined and made. It starts as an ore mined from the earth, which is then ...
From Ore to Finished Product
Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
