[QUOTE="thedigger, post: 208073, member: 2037"] Hi Jethro This is a very interesting subject and it is not cut and dry, .I have samples from ore that was processed 20 years ago,and they will still not give up the gold.You could say not all ores are the same I am sure that the more we look at the problem of these sulphides,the more we scratch our heads. I have treated these ores in many ways to release the gold,heating them in the muffle oven to 800c,then treat them acid,along the way I check by looking at them under a microscope,what I can tell you that they do not realease the gold easly. Regards for now Frank [/QUOTE]
