Indium & Gallium
Small correction to your quote Mr. D53. for Indium and Gallium prices.
Indium is at $730.00 kg. (not $720)-new price since last quote. Gallium is at $970. kg. (not $550.)
At 1.82 ppm= approximately 0.18 kg./ton Indium.
Assuming 1.82 ppm. Gallium = 0.18 kg/ton.
Indium at $730 X .18 = $131.40
Gallium at $970. X .18 = $174.60
Total value per tonne $306./ton
This is not just musing but.....amusing!
