Hazards and Control Measures of Molten Metal

 · Hazards and Control Measures of Molten Metal. By Admin. July 9, 2008 6:54 AM. Molten metal is a serious hazard in melting pouring appliions of metal casting. Workers who execute tasks with or near the molten metal are highly prone to risks, such as coming in contact with metal splashes or be exposed to electromagnetic radiation.

Cyanide hazards to plants and animals from gold mining and

To prevent flooding in mine open pits, and to enable earth moving on a large scale, it is often necessary to withdraw groundwater and use it for irrigation, discharge it to rapid infiltration basins, or, in some cases, discharge it to surface waters. Surface waters are diverted around surface mining operations. Adverse effects of groundwater ...

Guidance about explosion hazards

An explosion is a sudden and rapid increase in volume and release of energy in an extreme manner. This is usually accompanied by the generation of high temperatures and release of gases caused by changes in pressure, temperature and phase. In mining, explosives are the most obvious form of explosion hazard.
