The use of aqueous solutions for the recovery of metals.
Example: Leaching of copper oxide ores using a sulphuric acid solutions (or solution containing sulphuric acid). The Copper can then be recovered from solution using solvent extraction and electrowinning.

Is hydrometallurgy used in mining copper?
Hydrometallurgy is used for the processing of copper.Example: Leaching of copper oxide ores using a solution containing sulphuric acid. The Copper can then be recovered from solution using solvent extraction and electrowinning.
Metallurgy of gold and silver hydrometallurgy?
Hydromtellurgy is a subset of Metallurgy, and is used to process Gold and Silver.
What is the difference between pyro metallurgy and hydro metallurgy?
pyrometallurgy is carried out at higher temprature and hydrometallurgy is carried out at room temprature in aquas media.
Production of nickel metal from nickel sulphides by using Sherritt Gordon process?
The Sherrit Gordon process is one of the options for the processing of nickel sulfides. It is the first successful commercial application of pressure hydrometallurgy to a complex feed. The raw material is a pentlandite, NiS·FeS, concentrate which has been concentrated by various other processes.
Is flour and milk mixed a physical change or a chemical change?
It's a physical change. The various constituents of flour are all organic compounds, and water is usually a neutral medium with organic compounds (the only exceptions I know of are the various organic acids like acetic acid (vinegar)).However, if you ask this because you want to use flour that got soaked, I don't really recommend it. Flour is a very good source of carbohydrates, which lots of things can very easily digest. Wet flour has basically everything necessary for a lot of simple life forms, so it has a decent chance of mouldering or getting infested with insects.In general, chemical reactions are accompanied by one or more of:Temperature changeGeneration of light (though most of the reactions that do this are rather dangerous, like sodium and water, or TNT, or combustion (burning)Generation of bubbles (though this is also caused by heating things to boiling)Formation of a precipitate (seemingly clear water suddenly has small particles (like table salt) floating in it when something is added)Color change (like rust - iron to iron oxide... and steel is just iron with a bit of carbon in it)Source: answers.com question on indicators in chemical reactions.I'd also like to add rapid changes of physical state (solid-liquid-gas-aqueous, the latter of which is when you have something dissolved in water to the point where it can't be removed) to that list, though it's hard to see in lots of cases. Being a student in a hydrometallurgy class, I'd be remiss not to add the key indicator of importance in hydrometallurgy.

How do you use Hydrometallurgy to analyze a chromite sample?
chemically impossible...good luck on the lab though.

Which one is the best between hydrometallurgy and pyrometallurgy?
pyro is the best if and only if you have mineral processing background. It includes all smelters of copper,gold,platinum,iron ore,ferrous alloys etc and you also get the opportunity to work in coal extracting plants with the above mentioned advantage.
How copper can be extracted by hydrometallurgy but not zinc?
zinc is more electropositive and therefore is highly reactive metal.hence it can not be easily displaced from its solution of ZnSO4.on the other hand,copper is less electropositive and can be readily displaced from its solution more active metal such as zinc. Zn + Cu2+ ------> Zn2+ + Cu

What process is used to separate useful metals from ores?
Well, taking Manganese for example. Manganese is a chemical element, designated by the symbol Mn. In chemical Industry, manganese can be applied for making various manganese compounds such as manganese sulfate, manganese chloride, and potassium permanganate.Manganese mining and processing methods include mechanical separation, which includes ore crushing, washing, screening, gravity separation, high-intensity magnetic separation, and flotation separation, hydrometallurgy enrichment and chemical mineral processing method etc.
