The Experimental Research on the Separation for Floatation of the Sulfur and Arsenic in a Refractory Gold Ore

Abstract:

The ore belongs to a kind of refractory gold ore cotaining arsenic and high-sulfur, contains high-sulfur and low-gold, and arsenopyrite is the main host mineral for Au. Because the floating gold fine with arsenic from sulfur floatation. lead to high content of arsenic in sulfur concentrate. This part of the gold loss in the sulfur concentrate. By optimizing the structure of floatation flow and using the new inhabitor LY100 for arsenic, the indexes of small-scale closed circuit test were obtained: the sulfur concentrate grading at 48.78% with a recovery of 44.76% and with As 0.47%, the arsenic concertrate grading at 15.95% with a recovery of 75.14%.
