What is "Fool's Gold?"

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden

Mineral Formulae Recalculation

Pyrite, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, 'fire,' because pyrite emits sparks when struck by metal. Pyrite is called fool's gold; to the novice its color is deceptively similar to that of a gold nugget.

Pyrite surface environment drives molecular adsorption

Furthermore, we describe a spectroscopic surface characterization of the presence or absence of the surface ordering, as indicated by the L Prebiotic chemistry and the molecular origins of life

2022-06-18 · Pyrite is not the most stable mineral and will in time tarnish and loose its luster. Pyrite also has the bad habit of producing "black dust" when it rubs together. It is too late to save the beads once the process of decay starts there is nothing you can do in this case.

Pyrite Guide

Pyrite is also used in the cathodes of lithium non-rechargeable batteries. It further can serve as a semiconductor. Historically, it had other uses as well—scroll down to the History section to find out more. Pyrite is used in jewelry and may commonly be used as a substitute for marcasite, a mineral commonly mistaken for pyrite.

Pyrite: The Real Story Behind "Fool's Gold"

2022-04-01 · Pyrite is called "Fool's Gold" because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite's streak is brownish black. Read more about this sulfide (FeS2) mineral here.


The mineral pyrite, or iron pyrite, is iron disulfide, FeS2. It has isometric crystals that appear as cubes or pyritohedrons (twelve irregular, pentagonal or five-sided faces). Pyrite takes its name from the Greek word 'pyros' meaning 'fire' because sparks flew …

Minerals, Rocks & Rock Forming Processes

Minerals can be classified into several groups according to their chemical composition. These groups are: 1) Elements (carbon [], sulfur, zinc, gold, etc.) 2) Halides (element and halogen, such as chlorine, bromine, or iodine; one example is table salt [sodium chloride]) 3) Oxides (element and oxygen, hematite [iron oxide]) 4) Sulfides (element and sulfur, pyrite [iron sulfide

that pyrite quantity is critical in determining oxide zone mineralogy. Pyrite is a relatively refractory mineral in the replacement sequence; marcasite oxidizes more quickly than pyrite (Mason and Berry, 1968), and pyrrhotite oxidation is as much as two orders of magnitude faster than oxidation of pyrite (Nicholson and Scharer, 1994). Laboratory

Sulfides, Selenides and Tellurides: rebellious and

Pyrite, galena, sphalerite, and chalcopyrite are all common sulfide minerals that are found in many precious metal veins and other hard rock deposits. When metals combine with sulfur, the resulting mineral is called a sulfide. These minerals are the most important sources of most base metals like copper, lead and zinc.

:::AMD Basics

The mineral pyrite (FeS 2) and other sulfur containing minerals are common. Also common is the occurrence of these minerals in the geologic strata in the vicinity of coal seams. Mining coal inevitably involves exposing these pyritic materials to oxygen and water. In deep mines, these materials are exposed in the voids created by the mining process.
