Minimising the environmental impact of talc mining and processing All mining activities have an impact on the environment quarrying driving adits sinking shafts creating open pits mounding of overburden rock tailings and. Talc Mining & Extraction. Talc mining & extraction process plays an important role before milling process. After the talc ore is mined it is then washed to remove mud, dirt, foreign particles and other impurities by sand washing machine. The material is then naturally dried under the sun light. Talc mining companies are utilizing digital technologies to improve productivity and commercial outcomes as the major trends witnessed in the global talc mining market. 2001. 8. 9. (massive talc). In fact, these uses of talc are quite minor compared to its wide variety of applications in manufacturing and agriculture. High-quality (pure) talc has many physical and chemical properties favorable for its use, such as its softness, purity, fragrance retention, whiteness, luster, moisture content, Mining for resources extraction may lead to several geological and associated environmental changes due to ground movements, collision with mining cavities and deformation of aquifers. Being associated with minerals such as quartz, mica, kaolin, and asbestos, talc may cause different forms of pulmonary diseases depending on the nature of exposure inhalation of pure talc; inhalation of talc in association with silica (talcosilicosis); inhalation of talc in association with asbestos fibers (talcoasbestosis); and intravenous ingestion of talc (during recreational drug abuse). 2021. 4. 2.
