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.

A $130 million molybdenum (moly) processing plant is being constructed at Newcrest Mining's Cadia mine in New South Wales.The plant will extract moly from the mine'scopper concentrate stream to produce a 50 per cent moly concentrate in dry powderform, with an anticipated production of 4.1 million pounds a year.Construction began in February 2020, with …
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.
scavenging concentrates (i.e. underflow of secondary cyclone) is ground by using regrind mill that is a 3.962-m by 5.791-m ball mill. The tailings of the rougher flotation are discarded to the final tails, and the concentrate is reground. The concentrate of copper was produced by the stages of flotation cleaning and re-cleaning.

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.
According to the results, the average grade of molybdenum, copper and iron in molybdenum concentrate in mill-on (non-optimal) mode is 51.21%, 1.32% and 3.95%, respectively. While the average ...
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.
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.

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.

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.
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 ...
The rougher molybdenum concentrate is pumped to the molybdenum cleaning circuit for upgrade in a circuit that includes a regrind mill to reduce the particle size to a p80 of 38 microns and ten stages of conventional mechanical flotation cells. Final molybdenum concentrate is dewatered by a pressure leaf filter prior to leaching.
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 ...
MVC recovers copper and molybdenum from Fresh Tailings and Cauquenes Tailings in separate plants. Cauquenes Plant The Cauquenes coarse grinding circuit consists of three ball mills (one 16.5 x 18', 3,250 HP, one 17' x 28' 3,500 HP and one 16.5' x 22' 3,500 HP) using 1.5" steel grinding media.
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 Climax open-pit mine includes a 25,000 metric ton-per-day mill facility. Climax has the capacity to produce approximately 30 million pounds of molybdenum per year. The available mining fleet consists of ten 177-metric ton haul trucks loaded by two hydraulic shovels with bucket sizes of 34 cubic meters, which are capable of moving an average ...
Ball or rod mills crush and grind the mined ore to fine particles that may be only microns (10-3 mm) in diameter, releasing molybdenite from the gangue (worthless rock). The grinding mills on the right reduce rocks the size of soccer balls to the size of gravel. Further ball milling reduces the material to the consistency of face powder.
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.

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.
