Hi,
My name is Jeffrey, I manage a little benefitiation plant in Costa Rica. We concentrate artisanal tailings (gravity-flotation,which works well) and later we remove the gold (problem). We produce gravity concentrates in the order of 150-500 grams per tone and flotation concentrates in the order of 30-100 grams per tone.
We are having difficulties in the adsorption stage of our batch process. Which consists of 4 small pachucas of 1.300 L each, working individually, agitated by a positive displacement blower.
Our current recipe is:
I am getting terrible high tailings. At some point I was agitating with a compressor and according to my experience I was short in air, but things were more or less under control, but since I upgraded the air by using the blower, my results decreased significantly.
Please help me, all advise is appreciated.
Kind Regards,
J.
