1, different concepts.
Gold ore refers to gold-bearing ore mined from mines manually or mechanically, which also contains other metal impurities.
Chalcopyrite is a copper-iron sulfide mineral. It usually contains trace amounts of gold and silver. Crystals are rare, tetrahedral, mostly irregular granular and dense massive aggregates, but also kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled ochre. The stripes are slightly black and green.
Chalcopyrite is a common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal solution and contact metasomatism, and often forms a certain scale deposit.
Pyrite is iron disulfide. Pyrite is often mistaken for gold because of its light brass color and bright metallic luster, so it is also called "fool's gold". Pyrite usually contains cobalt, nickel and selenium and has NaCl crystal structure.
2. Different physical properties
The color of chalcopyrite is yellow, and the surface is often blue and purple-brown. Green and black stripes. Metallic luster, opaque, conductive and fragile. Pyrite is light brass yellow, and its surface is often yellowish brown and ochre. Stripes are green and black or brown and black. Strong metallic luster. Opaque. Cleavage, extremely incomplete Can be detected.
Pyrite is a semiconductor mineral. The color and streaks of natural gold ore are golden yellow to light yellow, which becomes lighter with the increase of silver content, metallic luster and opacity.
3. Different uses
Chalcopyrite is the main raw material for copper smelting in industry. In the field of gemology, it is rarely used alone and occasionally used as a substitute for pyrite. In addition, I often participate in the composition of some colored stones, inkstones and jade.
It is the main mineral raw material for extracting sulfur and manufacturing sulfuric acid. When associated elements contain gold, cobalt and nickel, they can be extracted. Pyrite is also a very cheap ancient gem. It can be used not only for grinding precious stones, but also as a base for jewelry, jade and other handicrafts.
Gold in natural gold ore has high electrical and thermal conductivity, good ductility and stability, so it is widely used in electronic industry. Aerospace technology requires high stability of radio and electronic components, and gold has this performance. Gold is also used as the lining of nuclear reactors. In aerospace and aviation industries, gold is used to coat the heat shields or screens of jet engines and rocket engines.
