Copper Ore Hydrometallurgy and Pressure Leaching-Copper-

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

Tantalum pentoxide - Wikipedia

Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta 2 O 5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings.
