MOLYBDENUM. Molybdenum (often referred to as "Moly") is an important metal in both the industrial world and our daily lives. It was found to be a distinct element by Carl Wilhelm Scheele in 1778 but retained its name from the Greek word 'molybdos' or lead-like. In its pure state, molybdenum is a lustrous grey metal, somewhat heavier ...
The bulk concentrate produced will be separated to produce market grade copper-gold-silver concentrate and molybdenum concentrate.

FCX's South America mining operations include open-pit mining, sulfide ore concentrating, leaching and solution extraction/electrowinning. Production from these mines is sold as concentrate or cathode under long-term contracts. Our South America mines also ship a portion of their copper concentrate to Atlantic Copper, our wholly owned smelting and refining unit in …
Molybdenum concentrate, gold and silver are also produced by certain of FCX's North America copper mines. FCX's Lone Star project located near its Safford operation in Arizona was substantially completed in 2020. The project continues to ramp up on schedule and is expected to exceed 200 million pounds of copper production for the year 2021.

Large rotary rakes move the molybdenite concentrate to promote the chemical reaction. Desulfurisation systems such as sulfuric acid plants or lime scrubbers remove sulfur dioxide from the effluent roaster gases. The resulting roasted molybdenite concentrate typically contains a minimum of 57% molybdenum, and less than 0.1% sulfur.
Each of the process trains consists of SAG mill - ball mills - pebble crushers ('SABC') primary grinding, bulk rougher/scavenger flotation, bulk concentrate regrinding and cleaner flotation circuits. The bulk concentrate produced will be separated to produce market grade copper-gold-silver concentrate and molybdenum concentrate.
scavenging concentrates (i.e. underflow of secondary cyclone) is ground by using regrind mill that is a m by 3.962-5.791-m ball mill. The tailings of the rougher flotation are discarded to the final tails, and the concentrate is re-ground. The concentrate of copper was produced by the stages of flotation cleaning and re-cleaning. In this flota-

The undersize is then pumped to cyclones in closed circuit with four 13 MW ball mills. The cyclone overflow is sent to 4 rows of 10 rougher flotation cells combined with a regrind circuit to obtain a bulk copper-molybdenum concentrate. The bulk concentrate is then sent to the molybdenum plant for further separation.
In the third staged development project, a second VTM-1250 regrind mill was selected for installation in Concentrator #2, to match the existing Concentrator #1 Vertimill. This resulted in approximately 25% spare regrind capacity in the Concentrator #2 design, complete spare parts interchangeability and potential future expansion capacity to ...
Rougher concentrate is combined with the regrind ball mill discharge and pumped to the closed-circuit cyclones. The target product for regrind cyclone overflow is P80 of 50 m. The processing facility consists of three crushing stages, ball mills, copper flotation stages, a molybdenum flotation circuit, and associated thickeners for concentrates ...
ammonium molybdate from molybdenum concentrate. In this processing, the ore was heated in air at 750ºC. The process converted the molybdenum sulphides to its oxides and evolved SO 2. Molybdenum oxides were then converted into sodium molybdate which was further changed into calcium molybdate and finally ammonium molybdate using different processes.
The molybdenum concentrate is bagged in 1.8-tonne tote bags and trucked to customers. The tailing slurry flows by gravity 7 km from the mill to the HH dam, at the upstream end of the 2-km-wide x 10-km-long (11,000-ha) tailings impoundment, where the tails disperse over the surface.
The resulting molybdenum sulfide (MoS2) is then roasted at between 500-600 C°(932-1112 F°) to produce roasted molybdenite concentrate (MoO3, also referred to as technical molybdenum concentrate). Roasted molybdenum concentrate contains a minimum of 57% molybdenum (and less than 0.1% sulfur).

The Sungun copper-molybdenum operation in Iran uses a typical copper-molybdenum flowsheet to produce separate copper and molybdenum concentrates through flotation and regrinding of the rougher concentrates arising from the primary circuit.
Vizcachitas is a large copper-molybdenum porphyry deposit located in the Rio Rocin Valley of central Chile. It is planned to be developed as an open-pit mine by Los Andes Copper, a Canadian mining company focused on the acquisition, exploration, and development of copper deposits in Latin America.
The molybdenum concentrate harder cleaned and cleaned again with corrections between stages to ensure maximum release. The flotation is conducted at high pH levels many times greater than 11 using lime to ensure good depression of sulphide minerals, particularly iron and copper sulphides.
A comparison of the amount of molybdenum recovered in the final concentrate with that of the rougher concentrate shows an 8.39% reduction in metal recovery. Considering the circuit shown in Fig. 1, as well as grade values, are shown in Table 1, molybdenum content increased from 0.86% to 48.70% after 8 stages of cleaner flotation.
Bulk flotation involves rougher, scavenger and cleaner flotation with associated concentrate regrind stages and is optimised by the Minerals VisioFroth system. Bulk copper-moly concentrate goes to a thickener prior to treatment in the molybdenum plant. Flotation tailings go to tailing thickeners and roughly 70% of the process water is ...
