Get a QuoteImportance of Laboratory Testing toLeaching PlantDesign Batch tests andcontinuous pilot plant testscan be conducted of the entireleach circuitto accurately determine the results of a full scale commercial operation. Process efficiency is often the controlling factor ofplantprofits.
Get PriceTheoretically, 2/3 of the total leach liquor in the Bagdad dumps has been treated in the pilot plant, without any apparent effect on the leaching efficiency in the dump* It should be noted, however, that the acid consuming Bagdad dumps are principally oxide mineralization, thus do not rely to a large extent on bacterial action for solubilization of the copper.
Get PriceThe process is particularly well suited for treating refractory gold ores, which give low recovery when directly leached with cyanide. SGS is a world leader in batch andpilot planttesting and flowsheet development for pressure oxidation processing.
Get PriceWe then calculate the sum ofcopperdigested during these three digestions and compare the calculatedcopperto a totalcopperassay. The data gathered during this testing is important for flowsheet development andpilot plantdesign. SGS sequentialleachingis a reliable solution to complexcoppermineralogy in gold orebodies.
