Glass Waste and Mining - tvrl.lth.se

2015-11-25  4. Barium glass •Without this type of glass, watching TV would be very dangerous. A television produces X-rays that must be absorbed, otherwise they could in the long run cause health problems. The X-rays are absorbed by glass with minimum amounts of heavy oxides (lead, barium or strontium). Glass containing barium is used for the TVs screen.

Impact of silica mining on environment

mining. sand falls by gravity to the bottom. After washing, the sand is then sent to a surge pile where water adhering to the sand particles infiltrates back into the ground. From the surge pile the sand is sent to the dryer and screening operation where the sand is dried in a drum with hot air blasted into it.
