  • Artisanal and Small-Scale Gold Mining Without Mercury

    In many countries elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials forming a mercury-gold amalgam which is then heated vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

  • The Difference Between Deflagration and Detonation

    Combustion (burning) is a process by which energy is released. Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds (slower than the speed of sound) it s a deflagration. If the explosion moves outward at supersonic speeds (faster than the speed of sound) it s a detonation.
