Mercury Exposure in Artisanal and Small-Scale Gold Mining
Introduction. For more than two decades, artisanal and small-scale gold mining (ASGM) has been operated in Indonesia, spread widely across 31 provinces.1 In West Java Province, ASGM is found in Bogor, Cianjur and Sukabumi Regencies. Commonly, ASGM in Indonesia uses mercury (Hg) in gold ore processing.2 Mercury is Laboratory-Scale Hammer Mill: It is a smaller version of industrial hammer mills designed for small-scale production. This is used in laboratories and pilot plants for evaluating new materials, carrying out quality control tests, and deciding optimal grinding parameters.Best 8 Hammer Mill Manufacturing Companies in India
