Huang Jing

Abstract

This gold deposit contains high arsenic and sulphur.The gold inside the ore is mainly dissociation free gold,and the second form is sulfide inclusion gold;Arsenic mainly exists in the form of arsenopyrite,realgar and orpiment.The collective concentrate has been obtained through dressing experiment research and single flotation process,the concentrate grade and recovery of gold is 66.354 g/t and 96.14% respectively,and the concentrate grade and recovery of arsenic is 37.064% and 96.42% respectively.
