Microfines

Microfines are extremely small particles, typically less than 45 micrometers in diameter, that are a byproduct of industrial processes, particularly in mining and aggregate production. These fine particles result from the crushing and grinding of rock and minerals. They are often separated from coarser materials during processing stages such as screening and washing. The composition of microfines varies depending on the source material, but they can include a range of minerals like silica, clay, and carbonate. Their extremely small size gives them a high surface area to volume ratio. In some industries, microfines are considered waste material and require disposal. However, they also have potential applications. For example, they can be used as filler materials in concrete and asphalt, as soil amendments to improve water retention, or as a component in the production of ceramics. Managing and utilizing microfines is an ongoing area of research and development in various industrial sectors to minimize waste and find beneficial uses for these fine particulate materials.
