Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.

Mar 04, 2021 The German grid emission intensity of 2018 was 469 gCO2eq/kWh. Assuming 60 kWh/kg of hydrogen and 28 kg hydrogen per tonne of hot metal, this would result in an additional 787.9 kgCO 2 compared to using green hydrogen. This means that emissions would be 36.9% higher compared to the reference case of injecting 120 kg PC per tonne of hot metal.
