issues with gold processing flotation

issues with gold processing flotation

Yet another gold removal process is flotation.The ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a foam. The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles. ...
