Metallurgy of gold and silver hydrometallurgy?
In gold hydrometallurgy, gold is extracted from ores using a leaching agent, such as cyanide, which dissolves the metal. The dissolved gold is then recovered through processes like carbon adsorption or precipitation. Silver hydrometallurgy follows similar principles, with silver often being recovered as a by-product in gold processing or through separate leaching processes tailored to its extraction. Overall, hydrometallurgy offers an efficient and environmentally friendly method for extracting and recovering gold and silver from their ores.
What is hydro metallurgy?
Hydrometallurgy is a process used to extract metals from their ores using aqueous solutions. It involves dissolving the metal from the ore, separating it from impurities, and then recovering the metal by precipitation or electroplating. Hydrometallurgy is commonly used for extracting copper, zinc, nickel, and other base metals.
What is the difference between pyro metallurgy and hydro metallurgy?
Pyrometallurgy involves using high temperatures to extract metals from ores, while hydrometallurgy uses aqueous solutions to dissolve and extract metals. Pyrometallurgy is typically used for high melting point metals, while hydrometallurgy is more suitable for low melting point metals or when environmental concerns are important.
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.
What are two main methods of metal extraction?
Some metals can just be mined since they do not form oxides or compounds, such as gold. Other metals form compounds which need further processing, such as lead and titanium. Iron ore is usually just heated until molten. This is smelting.

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

How do you extract nickel from scrap how to extract nickel from scrap?
Unfortunately nickel is usually alloyed into a metal; for example stainless steel has high chromium and nickel content in order to boost its corrosion resistance. When you scrap your nickel alloy, you should get payed accordingly to how much nickel is in the alloy.
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
