Assesment of the Gold Ore Floatability

Abstract

The article presents the results of gold ore beneficiation process. Two samples of ore, significantly differed in terms of gold content, were utilized for investigations. Samples were subjected the preparatory operations, consisting of fine comminution and classifica - tion. There were compared the results of flotational beneficiation obtained in two different processing circuits: directly after grinding and after pre-concentration operation with using the shaking table. The flotation operation has proven to be an effective method of concentration for this type of ore, the obtained concentrates were of a high gold grade, while the gold contents in tails were very low. In addition, the analysis of the results showed that application of gravity concentration prior to flotation process positively influenced the quality of flotation concentrates.
