underflow volumes before mine closure. The required cyclone underflow recovery rate was calculated to be 70%. Cyclone testing done some time before proved that a recovery rate of 74% was achievable with a feed density which averaged 1.31 t/m³. This was much higher than the density actually received during commissioning.Web

Gold particles were observed to be one to two microns in one dimension and 50 to 500 microns in the other two dimensions. This characteristic caused the gold to float across the conventional gravity tables and report to the tail. Gold was found to be concentrated in all cyclone underflow streams. The concentrations of the cyclone underflow streamsWeb

Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.Web

The grading of the gold plant residue is constant within certain limits. For the tests involving wider variation in cyclone feed grading, a system was evolved whereby cyclone underflow or overflow could be returned to the feed pachuca C and blended with incoming gold plant residue, to give a batch of pulp with a specific grading.
