Because olivine is one of the most common minerals on earth by volume supply shouldnt be an issue either and while mining crushing and transporting olivine to beaches will certainly contribute its own carbon emissions the scaled process if successful will more than offset its damage
A novel method for promoting olivine to fix co2 using electrolysis was introduced the nacl solution was electrolyzed to produce hcl and naoh solution the hcl solution was used to dissolve mg2 from olivine to form solution containing mg2 the naoh solution
Only about half of the olivine would be converted to carbonate because of the diffusionlimited process unless the olivine was milled to less than 100 nanometer 01 micron size so over 100 billion metric tons of olivine would need to be mined and milled annually to absorb those 356 billion metric tons of manmade produced co2

20121211ensp enspmining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself the effects of this damage can continue years after a mine has shut down including the addition to greenhouse gasses death
20191017ensp enspthe weathering breakdown of rocks is a natural process that locks up carbon dioxide in the air by chemical reaction when magnesiumrich olivine reacts with co 2 and water under natural conditions it forms magnesiumcarbonate and silicic acid this process locks up co 2 from the air into rocks with a new chemical composition
201942ensp ensp the fenotec binder process is an alkali system and as such is one of the few chemical binder processes that is compatible with olivine sand other processes such as furan and punb are not compatible for use with olivine sand due to acid neutralisation with the former and uncontrollable rapid curing with the latter process

The amount of olivine necessary for these applications is extremely large comparable to present day global coal mining 10 which would bring serious and vast mining impacts when energy inputs such as mining processing and transportation are included the overall energy requirement for enhanced weathering is huge 11
The evolution of the term olivine group is complex the earliest name given to an olivine group species was chrysolite and was named by johan gottschalk wallerius in 1747 although the name chrysolite was later used by balthasar georges sage in 1777 for what is now known as prehnite
