· Peruvians, probably the biggest exporters of pyrite to the USA and Europe, give most of their pyrite a bath in HCl before export. (I don''t know the concentration they use or time taken.) You could try the acid sold everywhere for use in swimming pools - In the USA that is often a mixture of HCl and phosphoric acid. Cheers, Alfredo

What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.
A slightly different version of mortar and pestle work is a variety called hand stamp crushing. A heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder. This iron cylinder is picked up and dropped onto the ore, much in the manner of the old time stamp mills.
