In one word, scarcity. There is a lot of pyrite, not much gold.

Is pyrite gold valuable?
Most pyrite is not valuable (I have heard estimates of 50 cents (USD) per gramme). Some pyrites contain traces of gold that increase its value, but it is mainly used for industrial extraction of sulphur. Large, perfectly cubic crystals of pyrite are valued by museums as exhibits.
Can gold and pyrite be distinguished by color?
Mostly, yes. Gold has a deep yellow colour, while pyrite often has a silvery haze over it. If you have a large sample, it's even easier, as pyrite forms perfect cubic crystals.
What is the real name for fools gold?
Pyrite
What mineral is sometimes confused with gold?
Iron Oxide. Pyrite is known also as "Fool's Gold"
Describe why color and streak are useful in identifying pyrite?
Pyrite's color is extremely similar to that of gold. However, the streak of pyrite is black. This can be used to distinguish it from gold.
What are four valuable heavy minerals that commonly make up veins?
Gold, Molybdenite, Silver, Pyrite.

When looking for gold in Californiawhat chracteristics would be the best way to distinguish gold from pyrite?
It can be identified in the field by the sulfur smell of the powdered mineral. Its metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold due to many miners mistaking it for the real thing, though small quantities of actual gold are sometimes found in pyrite. In fact, such auriferous pyrite is a valuable ore of gold.
What mineral property can be used to distinguish between pyrite and chalco pyrite?
Pyrite also known as "fool's gold" is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3. The chemical formulas are different. Gold's chemical formula is "Au" while Pyrite's is and iron sulfate mineral with a formula of "FeS2". The color is also different, gold appears the color of gold while pyrite is more bronze in color. The crystallographic form of the minerals also vary. Gold is a very soft mineral while Pyrite is much harder (gold has a hardness of 2.5 while Pyrite is 6.5). To distinguish between a sample of each, you could scratch the surface of gold using your fingernail which you would not be able to do with pyrite. You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite.

How could you determine if a mineral is pyrite or?
If you mean pyrite or gold- gold is soft- pyrite is brittle. Gold melts easily- pyrite does not. Acid dissolves pyrite, but not gold. Finally- you may have heard "All that glitters is not gold". It SHOULD be "NOTHING that glitters is gold." Natural gold may be shiny, but does not glitter- like pyrites will.
Is pyrite valuable to anyone in your society?
no
Sometimes called fools gold?
Iron Pyrite - which is a sulphide mineral - FeS2.
What is the real name for fools gold?
Pyrite
How do you separate gold in dirt?
Gold miners use a type of strainer to separate dirt from gold. They dip it into water because the dirt will rinse threw the strainer.
Where can you take your rock with precious metal in it to determine if it is real gold or fools gold?
If you possess gold (or iron pyrite) ore, it should be immediately clear whether gold or iron pyrite is present. You should be able to distinguish which of the two you have. Real gold is rounder while pyrite is more angular and sharp. Gold is relatively softer and more malleable than pyrite. Gold leaves a golden residue instead of a dark green/black residue as left by pyrite. Google images is a good resource for differentiating the visual contrast of the two.
Is it true if there is fools gold real gold is near?
Pyrite (fools gold) is usually found in Quartz veins, Sedimentary rock, and Metamorphic rock,as well as in coal beds. I once found a vein of pyrite in slate.
