The gold recovery of the gravity separation was estimated as 23.58% when the hydrocyclone underflow was the feed to the gravity separation stage and 45.33% with ball mill discharge. The gold recovery was calculated as 52.02% and 81.4%, respectively, when flash flotation was used in place of the gravity separation in the same flowsheets.Web
