Extracting Gold From Chloroauric Acid

Chloroauric acid (HAuCl) is an orange solid commonly encountered in gold refinement, extraction and chemistry. Many reducing agents reduce chloroauric acid to metallic gold, which falls out of solution as a yellow powder. Oxalic acid and sodium metabisulfite are often used in this way to produce the pure metal from dissolved scrap gold.
