About iron pyrites; unroasted
HS code 2502 covers iron pyrites, an important mineral resource that has a wide range of industrial applications. Iron pyrites, also known as fool's gold, is a naturally occurring iron sulfide compound that is mined and processed for use in various chemical, metallurgical, and agricultural industries. As a key raw material, the production and trade of iron pyrites plays a significant role in the global economy, particularly in sectors such as fertilizer manufacturing, sulfuric acid production, and metal extraction.
Production process
The production of iron pyrites typically involves mining the mineral from deposits found in the earth's crust. The mined ore is then crushed, ground, and processed to remove impurities and concentrate the iron pyrites content. Depending on the intended use, the processed iron pyrites may undergo further refining or chemical treatment to meet specific quality requirements.
Production inputs
The main inputs required for the iron pyrites industry include the raw mineral deposits, mining and processing equipment, energy sources, and water for various stages of production. Additionally, the industry may rely on other chemicals, reagents, and specialized machinery to facilitate the extraction, purification, and transformation of the iron pyrites into usable products.
Production outputs
The primary outputs of the iron pyrites industry are the processed and refined iron pyrites materials, which can be used as a source of sulfur, in the production of sulfuric acid 2807 Sulfuric acid; oleum, or as a component in certain fertilizers 3103 Mineral or chemical fertilizers, phosphatic. Iron pyrites may also be utilized in the extraction of other metals, such as copper, gold, and silver, through various metallurgical processes.
