Paper Title:
Behavior of Arsenic and Aurum Leaching by Roasting Arsenic Gold Ore
  Abstract

Aiming at the difficulties of aurum leaching from arsenic gold ore, the behavior of arsenic and aurum leaching by the roasting pretreatment of arsenic gold ore is discussed. The result indicates as the following: the rate of aurum extraction is only 14.16% to this kind of refractory gold ore by choosing normal method of aurum extraction. However, the rate of fixing arsenic is up to 95.77% and the aurum extraction rate is 78.45% through the pretreatment of fixing arsenic roasting under optimum roasting conditions like adding amount of CaCO3 by 3%, roasting temperature 650°C and roasting time 4 hours. The result is satisfactory.
