Her father is an independent consultant on water treatment and hydrometallurgy to the mining industry.

The complement to hydrometallurgy is pyrometallurgy, which is usually older technology.

Biohydrometallurgy is a subfield within hydrometallurgy which includes aspects of biotechnology.

Unit processes are usually broken down into three categories: pyrometallurgy, hydrometallurgy, and electrometallurgy.

Often hydrometallurgy involves the use of chelating agents, which can selectively bind certain metals.

Recent advances in hydrometallurgy have resulted in significant nickel purification using these processes.

Hydrometallurgy involves the use of aqueous solutions to extract metals or compounds from their ores.

For example, a major target of hydrometallurgy is copper, which is conveniently obtained by electrolysis.

In one application of hydrometallurgy, Cu is extracted into organic solvents as its saloxime complex.

Industrial mixer settlers are commonly used in the copper, nickel, uranium and cobalt hydrometallurgy industries.

Lixiviant is a liquid medium used in hydrometallurgy to selectively extract the desired metal from the ore or mineral.

This reactivity is the basis of many practical processes such, as the extraction of some metals from their ores in the process called hydrometallurgy.

Together with the cyanidation process invented in 1887, the Bayer process marks the birth of the modern field of hydrometallurgy.

Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose.

These specialties are generically grouped into the categories of mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.

It is also used as a leaching agent in chloride hydrometallurgy, for example in the production of Si from FeSi.

Precipitation in hydrometallurgy involves the chemical precipitation of either metals and their compounds or of the contaminants from aqueous solutions.

After completing his second master degree, he got his Ph.D. at the Imperial College London in hydrometallurgy.

The scope of electrometallurgy has significant overlap with the areas of hydrometallurgy and (in the case of fused salt electrolysis) pyrometallurgy.

In hydrometallurgy, the object metal is first dissociated from other materials using a chemical reaction, which is then extracted in pure form using electrolysis or precipitation.

Specific alloys are used in downhole and nickel hydrometallurgy applications due to their high strength (e. g.: titanium Beta C alloy), corrosion resistance, or combination of both.

The R&D division develops new processes and the technological and economical improvement of existing ones, applying techniques and procedures of disciplines such as hydrometallurgy and electrochemistry.

In 1920 Cappelen Smith was honored with the gold medal of the Mining and Metallurgical Society of America for distinguished service in the art of hydrometallurgy.

Extractive metallurgy of ferrous and non-ferrous metals can involve pyrometallurgy, but chemical processes like hydrometallurgy and electrometallurgy are far more common in method of non-ferrous extraction.

Subjects covered are cell design, electrochemical reaction engineering, corrosion, hydrometallurgy, the electrochemical treatment of effluents, molten salt and solid state electrochemistry, solar cells, new battery systems, and surface finishing.
