Key Difference – Pyrite vs Chalcopyrite

Pyrite and chalcopyrite are both sulfide minerals, but their chemical composition is different. Thekey differencebetween pyrite and chalcopyrite is thatpyrite contains iron sulfide (FeS2) whereas chalcopyrite contains sulfides of copper and iron (CuFeS2)。尽管具有相似的名称和略相似的化学配方奶粉,但它们的化学特性是不同的,并且用于不同的工业应用。

What is Pyrite?

Pyrite is a sulfide mineral containing iron (Fe) andsulfur(S) as structural elements. Its chemical formula isFeS2。It is also known asiron pyriteand “fool’s gold” due to its pale-brass yellow color. In the ancient days, people misunderstood pyrite as gold since it possesses a yellowish metallic luster similar to gold. It is one of most commonly found sulfide minerals, and also it can be found with other oxides in quartz veins,sedimentary rocks, and metamorphic rocks。Sometimes, it is found in small quantities of gold too. The word “pyrite” is derived from the Greek word “pyr”, which has the meaning “fire”. It got this name since pyrite can create sparks when it hits another mineral or metal.

Difference Between Pyrite and Chalcopyrite

What is Chalcopyrite?

Chalcopyrite is a copper iron sulfide mineral, and its chemical formula isCuFeS2。This mineral is naturally presented in a variety of矿石; from huge masses to irregular veins and it is considered as the most important copper ore. Chalcopyrite oxidizes to several types of oxides, hydroxides, and sulfates when it is exposed to the air. Some examples includebornite(Cu5FeS4),chalcicite(Cu2S),covellite(CuS),挖掘机(Cu9S5),malachiteCu2CO3(OH)2, and rare oxides such ascuprite(Cu2O). But, it is very rarely found with native copper (It is the uncombined form of copper which occurs as a natural mineral).

Key Difference - Pyrite vs Chalcopyrite

What is the difference between Pyrite and Chalcopyrite?

Appearance of Pyrite and Chalcopyrite:

Pyrite:It has a pale brass yellowish color with a metallic luster.

Chalcopyrite:黄金黄色是黄铜黄色的。

Chemical Composition of Pyrite and Chalcopyrite:

Pyrite:Pyrite has the chemical formula FeS2, and it is an iron sulfide mineral.

Chalcopyrite:The chemical formula of chalcopyrite is CuFeS2。It is a copper iron sulfide mineral which has a greater economic value since it is the most important copper ore on Earth.

黄铁矿和黄铜矿氧化程度:

Pyrite:通常,精细结晶的黄铁矿矿物质相对稳定,这些矿物质是由沉积浓度分解(通过化学反应将材料分离到其成分中的分离过程)的。黄铁矿在潮湿的环境中缓慢氧化,并排出过程中形成的硫酸。

Chalcopyrite:In the exposure to the air, chalcopyrite forms not only one compound but several types of oxides, hydroxides, and sulfates. Examples of some sulfates are; bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), digenite (Cu9S5). Malachite Cu2CO3(OH)2is an example for a hydroxide and cuprite (Cu2O) is a rarely produced oxide. Chalcopyrite very rarely oxidizes to native copper.

黄铁矿和黄铁矿的用途:

Pyrite:黄铁矿用于生产用于造纸工艺的二氧化硫。它还用于通过热分解黄铁矿来产生硫酸(FES2) into iron (II) sulfide (FeS) and then to elemental sulfur at 540 °C; at 1 atm.

Chalcopyrite:在工业尺度上,黄铜矿主要用作主要的铜来源。即使它主要只有一种用法;这被认为非常重要,因为铜线在现代社会的几乎所有电子设备中都使用。
