The pyrite in which small amounts of gold occurs is of crystalline variety primary pyrite. The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism due to a fine coating of a iron compound.
Mar 07, 2013 Arsenopyrite is arsenic iron sulfide, which is the same type of mineral as pyrite fools gold, iron sulfide, but with a heavy addition of arsenic. If one attempts to heat or in any way alter the mineral, a strong garlic odor of arsenic will be produced as lethally toxic, corrosive and carcinogenic vapors are released.
4 Avoid Lapis LazuliPyrite Fluorite crystal alcohol based perfumes. Unless they are 100 alcohol, that completely lacks any water. Water will cause a dangerous biohazard chemical reaction. skull Lapis Lazuli sometimes has Pyrite with it. Any lower quality Lapis would definitely have tiny specks of Pyrite

The potential dangers of pyrite are threefold 1. It has a strong acidifying effect, i.e. it drops the pH. 2. In addition to iron it sometimes contains small quantities of other more dangerous heavy metals such as lead, zinc, and copper.
Apr 01, 2014 Pyrite is a widespread natural source of arsenic, which can leach into ground-water aquifers when geologic strata containing pyrite are exposed to the air and water, during coal mining for example. Acid mine drainage and groundwater contamination requires close monitoring to ensure that it has been neutralized before being returned to the earth.
