The overall process is one of hydrometallurgy and begins with a heptafluorotantalate.
2.
The overall process is one of hydrometallurgy.
3.
Egypt had submitted the Hydrometallurgy Pilot Plant design information and had agreed to provide ICRs.
4.
Unit processes are usually broken down into three categories : pyrometallurgy, hydrometallurgy, and electrometallurgy.
5.
The hydrometallurgy technology was piloted at a demonstration plant that opened in Argentia, Newfoundland and Labrador in 2004.
6.
Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose.
7.
Together with the cyanidation process invented in 1887, the Bayer process marks the birth of the modern field of hydrometallurgy.
8.
This demonstration plant operated until 2008 and was instrumental in helping Vale decide to use the hydrometallurgy process for the Long Harbour processing plant.
9.
It is also used as a leaching agent in chloride hydrometallurgy, for example in the production of Si from FeSi . ( Silgrain process)
10.
The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and electrometallurgy where it is used to produce useful metals.
