Arsenopyrite Facts Softschools.com

Arsenopyrite is one of the important ores containing arsenic and is most often found in metamorphic rocks. In old literature the name of arsenopyrite is mispickel which has a German origin. The ore is very hard and has a measurement of 6.1 on the specific gravity scale. The color of the ore ranges from a silvery white to a darkish grey.

Use in Mining International Cyanide Management Code

Ore that contains free gold and/ or silver may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large metal particles. Such ore may first be subject to a gravity recovery process to recover the free gold and /or silver before being subjected to cyanide leaching.
