Abstract:

Horizontal press filter is widely used in gold concentrator,but in some demanding gold processing plants for the cake moisture or filtrate turbidity,horizontal filter press beyond its power.Vertical automatic filter press,which is rarely used in dewatering process,with no more mature application experience and case in gold concentrator.Because of its function and the effect,it has the possibility to be a substitute for horizontal press filter in the process of dehydration, pressure filtration, and washing. In this paper,based on the introduction about the structure and operation principle advantage in the gold concentrator of the vertical automatic filter press,using a series of application data in Shandong Gold production,and compared the solid-liquid separation capability of vertical automatic filter press with conventional equipment,analyzed its application effectiveness.The results show that the automatic vertical pressure filter has lower cake moisture content than conventional filter press,and with excellent technology indicators in dehydration and cyanide washing process of flotation products,its value is more prominent, especially in the higher solid-liquid separation requirements processes,through introducing automatic vertical filter press, Shandong Gold concentrator has economic returns of 2.901 million yuan per year.
