摘要： The present disclosure relates to a process and system for recovery of one or more metal values using solution extraction techniques and to a system for metal value recovery. In an exemplary embodiment, the solution extraction system comprises a first solution extraction circuit and a second solution extraction circuit. A first metal-bearing solution is provided to the first and second circuit, and a second metal-bearing solution is provided to the first circuit. The first circuit produces a first rich electrolyte solution, which can be forwarded to primary metal value recovery, and a low-grade raffinate, which is forwarded to secondary metal value recovery. The second circuit produces a second rich electrolyte solution, which is also forwarded to primary metal value recovery. The first and second solution extraction circuits have independent organic phases and each circuit can operate independently of the other circuit.

摘要： A method of recovering molybdenum includes introducing resin comprising molybdenum anions into an elution vessel and eluting (separating) the molybdenum anions from the resin to form a molybdenum rich eluent. Small amounts of uranium within the eluent is precipitated into sodium diuranate and removed. A further precipitation process is performed to form ferrimolybdate from the molybdenum rich eluent, thus recovering molybdenum. The resin comprising the molybdenum anions may be generated by (1) moving a pregnant lixiviant (containing uranium and molybdenum) through a first extraction apparatus to capture uranium anions in resin and producing a barren lixiviant (containing mostly molybdenum, with small amount of uranium), and (2) moving the barren lixiviant through a second extraction apparatus to capture mostly molybdenum anions in resin.
