Aug 23, 2016 · Mining activities expose workers to silica dust, which has contributed substantially to the TB epidemics in southern Africa and other low income regions of the world . About million workers in the United States are potentially exposed to silica dust [ 4 ].
The hydrophilic nature of silica pigment further promotes the absorption of the silica coating [7]. One factor limiting the wider use of silica pigments is the low solids content (30%) of silica coating formulas [7], which limits the coating speed of the color, for example. Another restrictive factor is that the high specific surface area of ...
Dec 08, 2018 · Battery operated lowvolume air pumps were used to collect samples from the breathing zone of representative miners and ore processors. Silica samples were collected with an aluminum cyclone (SKC) designed for a 4 µm 50% cutpoint and pumps calibrated to draw l per minute with a primary standard flow meter (Mesa Labs Biodefender 510).
