This ore from Vietnam contains a lot of slime, disseminated extent of valuable mineral is fine, and the gold grade of raw ore is low; therefore, this ore is hard to concentrate. Through the study can be found that qualified indices are not able to be obtained through single gravity separation or single flotation. Based on the analysis of test data, and taking the nature of the ore into account, proposed a united process of gravity separation and flotation. The test results show that the process has achieved qualified results.
