Arsenopyrite is considered hazardous due to its arsenic content, which can pose significant health risks if inhaled, ingested, or absorbed through the skin. When disturbed, arsenopyrite can release toxic arsenic compounds into the environment, potentially contaminating soil and water sources. Chronic exposure to arsenic can lead to serious health issues, including skin lesions, respiratory problems, and increased cancer risk. Proper handling and safety measures are essential when working with or near arsenopyrite.
An arsenopyrite is a silvery-grey ore of arsenic - a mixed arsenide and sulphide of iron, chemical formula FeAsS.
Arsenopyrite isn't really "marketed" as such. This mineral, FeAsS, is the principle ore of arsenic. It is recovered by mining, and it is usually processed on or near the site to recover the arsenic. (It is almost always cheaper to process any ore near the mine because transportation costs associated with moving ore are high.)
At least six: native arsenic, realgar, orpiment, arsenopyrite, lollingite, and enargite.

When metalloids are found in nature, they are usually in the form of compounds or minerals. They can be commonly found in ores such as bauxite, borax, or arsenopyrite. In their pure elemental form, metalloids are rare in nature.
'streak' is the color that a mineral will leave when rubbed on a piece of unglazed porcelain. It is used to help identify the mineral. For example, arsenopyrite looks very similar to gold, but has a dark grey or black streak. Gold has a yellow streak.
