Caracterización metalúrgica del circuito de flotación en la planta de procesos Fruta del Norte LundinGold

Abstract

Abstract: The purpose of the present work was to studythe flotation circuit of the LundinGold process plant, such said circuit is the most important process for the concentration of gold, silver, etc.,this allowed obtaining results that helped determine the conditions in which operatessaid circuit, especially to determine its recovery efficiency.Three samples were carried out and the different operating conditions were analyzed, granulometric analysis:meshes and valued, metallurgical balances per stage and global, were completed, in order to determine the recovery of gold, silver, sulfur, iron and arsenic for each stage and circuit, and in the same way by fraction of particle size. Concludingthat the first sampling presented greater recovery in front of the other two, achieving 81.68% gold recovery. In addition to that in the granulometric analyzes the distribution of gold and silver are in greater proportion in the fraction of size (mesh -400). In the tailings it was evidenced that there is displacement of gold, silver and sulfur, around 3% above the design criteria, but these do not affect the efficiency of the process.
