Codelco from its four copper mining divisions in Chile, and Phelps Dodge from one molybdenum-only and three copper mines in the USA, are by far the biggest producers, together accounting for about a third of world mine production
By Michael J Magyar Domestic survey data and tables were prepared by Cindy C Chen, statistical assistant, and the world production table was , In 2003, reported consumption (roasting) of molybdenum concentrate was 27,500 t, an increase of about 6,300 t compared with that of 2002 The increase resulted from increased , Codelco decided ,
Facilities To Roast Molybdenum Are Strengthened Mainly By Major Enterprises (1) , ( Xstrata ) is roasting molybdenum on toll consignment from Codelco but the contract for this roasting is anticipated to expire for the future, and (4) Codelco has planned to produce 100 million lbs / year of molybdenum in concentrate from 2010 and ,
Cooling equipment to help companies be more , May 29, 01 By CNMining 112 Comments Ontario-based MFS Systems (2007) Inc said its cooling equipment could help large companies such as Chile’s copper producer Codelco and molybdenum processor Molymet increase their profits while maintaining high environmental standards
This project Outotec supplies to Codelco a roasting plant for Cu- and As-containing raw materials that after roasting will have to be cooled prior to transport from the roasting plant to the copper smelter

The largest molybdenum producers are Molymet (Chile), Freeport McMoran, Codelco, Southern Copper and Jinduicheng Molybdenum Group Applications More than half of all molybdenum produced ends up as an alloying agent in ,
Codelco produces 877,000 mt copper in H1, up 4%; ,
Codelco also lifted output of molybdenum by 41% to 16,000 mt, while production of silver rose 35% to 173 mt , Operational difficulties with the roasting plant, used to reduce the arsenic content of ore extracted from the open mine before smelting, has forced Codelco to ship more copper as concentrates rather than refined cathode .
The mine is expected to produce 220,000t of copper, 11,000t of molybdenum and 2t The processing plant initially processes 110,000tpd, which is expected to READ MORE copper and molybdenum process plants mining - YouTube
