Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.[1] Production of reagents for mineral processing to ...

Write the Chemical Reactions Involved in the Process of …

The remaining lead-gold-silver residue is treated by a process in which the residue is heated to a high temperature (about 800 C ) under strongly oxidising conditions. The noble silver and gold remain in the elemental form, while the lead oxidises and is removed.

Silver Ore

In the cyanide extraction process of silver from argentite ore, the oxidising and reducing agents used are O 2 and Z n dust respectively. Reactions are: A g 2 S + 2 C N − + O 2 → 2 [ A g ( C N ) 2 ] − + S O 2

How silver is made

In this process, ore was heated with rock salt, producing silver chloride, which was leached out with sodium hyposulfite. Today, there are several processes used to extract silver from ores. A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores.

Silver: A native element, mineral, alloy, and byproduct

The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral''s atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral.

Silver mining

Silver has been known since ancient times. Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC.The silver mines at Laurium were very rich and helped provide a currency for the economy of ancient Athens, where the process involved mining the ore in ...
