Definition: The word "archispore" refers to a specific type of mineral that occurs in rocks and other minerals, primarily found in areas with low pH levels, and can also include iron sulfide deposits. It has a very small pore size (approximately 10-30 micrometers), making it ideal for mineral processing applications as it facilitates the extraction and separation of minerals from the rock. The term is used to describe specific types of rocks or minerals with relatively low pH and high silica content, especially in areas where these conditions are conducive to mineral exploration.
