anybody familiar with that specific test, is it  conclusive ? 

does it give accurate results ?

anyone have the full procedures with calculation 

what is the lowest ppm does it work for?

we have small scale mine and we don't have atomic adsorption available at this stage.
 
my question is about calculating gold concentration in cyanide solution, we come to  lead acid method but we don't know its accuracy and full procedure.
 
Thank you

This is called a Chiddey assay & I have tested this against AAS in the 80's...we consistently got better results w/the Chiddey method...however it is labor intensive & time consuming...note that consistency is dependent on the expertise of assay personnel; check out Bugbee for the procedural.
