Ann: High-Grade Antimony Recovered at 98% from U.S. E-Waste, page-83

How much antimony in a P.C. board now remember that it's an additive use in miniscule amounts for metal hardening or fire retardant
They pump up the ann on the % of extraction but fail to say what amount was extracted vs the amount of waste put through this whizz bang tech.
Any guess i would say it would be so low that it wouldn't be economically viable the gullible swallow the % numbers like how amazing.
Every other ann is like pick the hot metal of the week this time antimony then we had gallium. Lithium and whatever else is trending and bang yes sir we can extract any bloody thing. HYPE will carry you so far reality is show and tell let see that massive pile of antimony you just extracted that photo under the microscope would be accurate as you would need one to see the piddling amount extracted.
