Developed Process Circuit Flowsheet of Al Amar Ore
Al Amar gold ore is rich in sulfides of base metals and is commercially applied for the production of copper concentrate via floatation and gold bullion by cyanidation of tailing The current process flowsheet suffers from low gold recovery (∼60%) and loss of metals in the hazardous stockpiled residue This work addresses these drawbacks by a newly experimental redesign of the process FLOWSHEET OPTIONS CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating lowgrade gold ores because of its low cost Between 1020% of the gold recovered each year from primary sources is extracted by this technique The advantages of this process are: • SimplicityFLOWSHEET DEVELOPMENT FOR GOLD OREBODIES Developed Process Circuit Flowsheet of Al Amar Ore for Production of Nanocrystalline Ferrite and Improving Gold Recovery Mohamed H H Mahmoud,* Mahmoud M Hessien, Mohammed Alsawat, Abel Santos, Nader ElBagoury, Abdullah K Alanazi, and Naif A Alshanbari Cite This: ACS Omega 2020, 5, 30858−30870 Read OnlineDeveloped Process Circuit Flowsheet of Al Amar Ore for The flowsheet showed the results obtained from testing a complex leadzinccopperiron ore containing values in gold Exceptionally high grade and recovery were obtained in this instance Utilizing a patented process special reagents made profitable production Mineral Processing Flowsheets 911 Metallurgist gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations The production of a copper gold concentrate is also an option where the copper is of a marketable gradeFlowsheet Options For Processing Copper Gold Gold
