Gold recovered with mercury again mixed with mercury

This is about 14 grams of gold that miners upon my insistence recovered by simply panning the gold concentrate. They have first recovered all the gold without mercury.

I was happy, and came there to see the result and eventually buy the gold. We are buying only environmentally friendly recovered gold. That means that gold recovered with mercury we are not to buy. We do tolerate our clients who are buying such gold and advising them how to buy it safely.

When I have arrived on this location we found gold in the form of balls as collected with mercury. So I asked what is this? I was thinking it was recovered without mercury.

They explained that as gold was in the dust form, their manager went to use mercury to make these balls.

I could not believe it.
