Impact of talc mining

Study Background. NIOSH studied the health effects of mining and milling talc. The study included 710 men who mined or milled talc. The study included all men who had worked for at least 1 day between 1947 and 1978. The purpose of the study was to see if exposures at this work site were associated with lung disease, including cancer

    Aug 12, 2020 This manuscript aimed to examine the impact of operating parameters on the wet grinding of talc in a vertical-type stirred media mill. Within the scope of the research, the effects of operating parameters including media filling ratio, solid mass fraction, grinding media size, and grinding time were studied. The findings were assessed based on the product particle size (d50, d10), surface
