The technological process of obtaining microspheres begins at power plants, where the combustion of hard coal generates an ash-slag mixture. Next, the wet ash-slag slurry is transported to storage sites (lagoons). In contact with water, the light microsphere fractions separate from the heavier ash and slag. Thanks to a system of overflow wells, channels, and pipes, the microspheres are transported to drainage chambers, where preliminary cleaning and water filtration take place, along with the removal of natural impurities.

The next stage is the processing line, where the microspheres undergo further cleaning and drying. The final moisture content of the product (0.5%) is achieved during thermal treatment, which also allows for fractionation of the microspheres by grain size. The finished product is packed according to customer requirements—in 20 kg paper bags, 500 kg big-bags, or in bulk into tankers. The packaging is secured with shrink film to preserve the physical properties of the microspheres during transport and storage.
