Testing design for downhole leaching of copper ores from Erdenetiin-Ovoo deposit

摘要

Testing design for downhole leaching of ores at theCentral are of Erdenetiin-Ovoo deposit substantiates the first stageof mastering of the technology and aims on determination ofprincipal possibility of deposit development using developedtechnology. Testing of ores leachability was anticipated via one-hole scheme using air oxygen as oxidizer of sulfide ores, testing of5-6 different leaching solutions and 4-5 conditions of theircirculation in ore body is also anticipated. Duration of pilotoperations makes 3-3.5 months.
