The results indicated that the recovery of molybdenum was largely dependent on the concentrations of Na 2 CO 3 and H 2 O 2 in the reaction medium, which controls the acidity of the leach liquor and carry over of impurities such as Al, Ni, P, Si and V. Leaching process was exothermic and leaching efficiency of molybdenum decreased with Cited by: Processing of leach liquor. Leach liquor can be processed in different ways to recover molybdenum as calcium molybdate, ammonium molybdate, molybdic acid or molybdenum oxide (Juneja et al., , Kar et al., , Kar et al., ).In the present study, recovery of molybdenum as MoO 3 was tested using the reported precipitation conditions of ammonium molybdate method (Kar et al., ).Cited by: Questa Molybdenum Mine (Questa Mine; Moly Mine; R and S Mine), Questa, Taos Co., New Mexico, USA: A molybdenum-rhenium mine owned by Molycorp, a subsidiary of Unocal Corp. Produced 4, tons of Mo in concentrates (). In , the mine was declared a superfund site - . Molycorp, Inc. mines molybdenum ("moly") a few miles east of Questa, New Mexico. The mine itself dates back to the 's. In , Molycorp began open pit operations. In , it returned to underground mining.

  The present study proposes three distinct processes to recycle rare earth elements (REE) from two low-grade secondary resources: REE-containing mine tailings and ferrous scrap from shredded waste of electrical and electronic equipment (WEEE). The first developed process extracts both REE and phosphorus from the apatite mineral contained within the mine tailings by way of acidic leaching Cited by: 2.
