Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). [3] It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage.
For example, a dental amalgam is formed by combining particles of a metal, usually gold or silver, with mercury. In organic chemistry, trituration is a process used to purify crude chemical compounds containing soluble impurities.
Amalgam (chemistry), the combination of mercury with another metal Pan amalgamation, another extraction method with additional compound; Patio process, the use of mercury amalgamation to extract silver
Sodium amalgam is a by-product of chlorine made by mercury cell electrolysis. In this cell, brine (concentrated sodium chloride solution) is electrolysed between a liquid mercury cathode and a titanium or graphite anode. Chlorine is formed at the anode, while sodium formed at the cathode dissolves into the mercury, making sodium amalgam.
Aluminium amalgam may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire to react with a solution of mercury(II) chloride in water. [ 1 ] [ 2 ] This amalgam is used as a chemical reagent to reduce compounds, such as the reduction of imines to amines .

Amalgamated zinc is zinc that has been surface treated with mercury to form a surface amalgam containing little contamination from other elements. It is typically used for reduction, and is written as Zn(Hg) in reactions.
