The clanking grinding sounds of the ball mills drown out normal conversation on the floors above. Worse, mercury added to the ore in the ball mill is released into the air with the dust. Once ground, the ore is panned with mercury and water to create a paste-like amalgam which is then pressed into a plastic bag and burned with an acetylene torch.
