The estimate used for gallium in the earth's crust is around 16.9 ppm (for comparison, copper is estimated to be around 50 ppm in the earth's crust and aluminum is around 82,000 ppm).
Currently, almost all lithium mining occurs in Australia, Latin America, and China (accounting for a combined 98 percent of production in 2020). An announced pipeline of projects will likely introduce new players and geographies to the lithium-mining map, including Western and Eastern Europe, Russia, and other members of the …
When used as a monopropellant, hydrogen peroxide ensures 11% lower specific impulse even when 98% hydrogen peroxide is used (98% is the highest commercially available concentration). It should be noted that, in going from 87.5% to 98% hydrogen peroxide, the theoretical specific impulse increases by 12 s (for hybrid …
