USING CORN STARCH TO EXTRACT GOLD FROM THE ORE IS A HUGE CLAIM

EXTRACTING GOLD FROM THE ORE WITHOUT THE USE OF CYANIDE

Researchers at Northwestern University in Illinois have discovered a new method for mining gold which is inexpensive and non-toxic, reports Phys.org.

Instead of cyanide, the procedure uses cornstarch to separate gold from raw materials. It can also be used on consumer electronic waste to recover the gold from them.

The research team found the method by accident during laboratory testing.

A university spokesman said the elimination of poisonous cyanide from the gold industry is of utmost environmental importance.

Most gold miners currently use the toxic leaching process to isolate the yellow metal from the ore.

Why not use Thio-Red? it is non toxic, cheap and is American made.

Sugars are known reducers of precious metals and even of the base metals (even bad Cr 6) so what is all this fuss about precipitating potassium-aurobromate from solution? Ok Is selective, So What? How do you get the “green gold” from ore to solution? Ok with bromic acid. So where is the new gimmick?
