Zangezur Copper–Molybdenum Integrated Works has successfully been implementing construction and upgrading of all process stages at the processing plant in recent years, expanding the marketable output, improving the qualitative–quantitative indexes of the products and reducing the maintenance costs. The prime contractor for the processing plant construction and upgrading at Zangezur CMIW is RIVS that also acts as the general designer and equipment supplier, exercises installation and start-up supervision, as well as construction arrangement. Stage I of the processing plant construction was accomplished in 2004–2010. The annual capacity of the plant was increased from 8 to 13.5 Mt, and the copper and molybdenum production data were improved at the same time. Stage II of the processing plant design, construction and upgrading covers the period from 2010 through 2014, with gaining annual capacity of 20–25 Mt. For the first time in the CIS countries, RIVS and Zangezur CMIW have jointly actualized the project of wet semiautogenous milling floor, involving mill SAG-10.34×4.6 with the cubic capacity of 406 m3 and ball mill MSHTS-6100×9500 with the cubic capacity of 260 m³, on the industrial infrastructure site of the integrated works. While operating, the processing plant continuously improves the production data although the content of useful components in ore reduces. This justifies the adequacy of the accepted development strategy in terms of the chosen technology and equipment, given the fruitful cooperation between Zangezur CMIW and RIVS.
