Recovery of Molybdenum from Copper Slags

Biomining of MoS2 with Peptide-based Smart Biomaterials

“…In order to suggest peptides as recognition and capture elements for MoS 2 mining from tailing ponds, their specificity becomes an important parameter. Therefore, the main components of copper slags – MoS 2 , Mo, MgO, SiO 2 , Al 2 O 3 , CaO, S, Fe 2 O 3 , Cu, Tungsten and Zn 33 , 34 – were tested as possible targets for MoS2-P15 and MoS2-P28 (Fig. 3A ).…”

Research into resource-saving molybdenum-containing alloying additive, obtained by the metallization of oxide concentrate

“…In other words, it is expedient to study the regularities of restoration and carbide-formation at relatively low temperatures of metallization of oxide molybdenum concentrate with the goal of reducing the losses of Mo with its oxides by sublimation. Positive results of the use of the carbon-thermal restoration were obtained during recycling of Mo from molybdenum-containing slag, formed during production of copper [13]. Their Mo content was about 0.3 % by weight.…”

Determining the patterns of phase and structural transformations at carbon­thermal reduction of molybdenum concentrate

“…Positive results of the application of carbothermal reduction was obtained at the disposal of Mo from molybdenum-containing slags formed in the production of copper [11]. Their Mo content was about 0.3 % by weight.…”

“…This is an additional confirmation to the fact that obtaining a carbon-free product by applying the carbon-thermal reduction of oxide molybdenum-containing raw materials is not possible. The data and temperature indicators of reduction, specified in papers [11,12], should be considered when developing technological parameters for the oxide molybdenum concentrate reduction. However, the character of reduction and the resulting carbide phases in the systems investigated in papers [11,12] and at carbon-thermal reduction of oxide molybdenum concentrate, may vary.…”
