Jul 19, 2019· Since silver production is primarily a byproduct of industrial metals mining, its annual production relative to its above ground supply swings wildly between as low as 20 or 30 to 1 to as high as 70 to 1 (70 to 1 is common for gold – that is, 70 years of production equals the above ground pile).

CO 2 is also the main byproduct of coal combustion: nearly 4 grams of CO2 are produced for every gram of carbon burnt (depending on its type, coal can contain as much as 60 to 80 percent carbon). Methane (CH4) often occurs in the same areas that coal is formed, and is released during mining activities.
