I am doing a research on the processing of refractory gold and part of the research I have to do cyanide leaching to prove that the gold is refractory and also an acid digestion test which helps prove that the gold is refractory. Refractory gold in simple is gold that cannot be extracted through conventional means i.e through cyanide leaching because the recovery rates are very very low.
My problem is I do not know what is acid digestion test and how do I perform it on gold
