Molybdenum is commonly used in the consumer, energy, industrial, medical, agricultural, aerospace, and transportation markets. The silvery-white, very hard metal has the sixth highest melting point of any metal and is often used to create high strength alloys and superalloys.
The tailings from the molybdenum plant are the final copper concentrate (typically greater than 30% copper). Following molybdenum rougher flotation and several stages of cleaning, a final molybdenum concentrate is produced.

The present research aims at recovering copper by reprocessing of tailings at China Molybdenum Co. Ltd. (CMOC) from bench-scale to industrial tests. It focuses on the determination of the reagents' dosage and pulp concentration that enables to obtain the highest recovery of copper by flotation of the studied tailings.
the final concentration tailings are the product with the copper content of 0.2–0.5% and molybdenum content of 0.1– 02%. Such copper content is explained by the presence of aggre-

1959 – Pre-mine development: 1961 – Mill began operating at 15,000 tons per day. 1967 – Two additional rod mills and one flotation section added tobring capacity to 22,000 tons per day.
Zangezur Copper Molybdenum Combine “Zangezur Copper Molybdenum Combine” Closed Joint Stock Company (ZCMC) is a leading Armenian mining company with headquarters in Kajaran, Armenia. ZCMC operates large, long-lived, assets with significant proven and probable reserves of molybdenum and copper.
Processing. We produce molybdenum and copper concentrates, which are then roasted and smelted in and outside of Armenia. The ZCMC processing plant is a mature facility plant with an established processing track record that has managed well the increase in throughput over the last few years.
Copper and Molybdenum Flotation Circuit Copper / Molybdenum Flotation Circuit. Molybdenum (moly) is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. ... Filters dewater these tails further, or a tailings pond stores them. Bulk (Copper-Moly) Thickener.
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.
Welcome to the official web-site of the “Zangezur Copper Molybdenum Combine” Closed Joint Stock Company Thank you for your interest in our company and operations! For already more than 60 years our company is a leading company in copper and molybdenum mining and processing.
The tailings are pumped to the tailings management facility for storage and water is returned via parallel piping to the process plant for reuse. The Constancia deposit is a porphyry copper-molybdenum system, which includes copper-bearing skarn mineralization.
Copper and molybdenum concentrates and tailings will be produced. The proposed process includes crushing and grinding of the ROM material, bulk copper-molybdenum rougher and cleaner flotation, regrinding, copper-molybdenum separation, molybdenum flotation, and dewatering of copper and molybdenum concentrates.
That was a big plus for Amerigo because these tailings were initially processed using older extraction methods, so they contain more copper and molybdenum than the fresh tailings.
MVC has been in operation since 1992 and produces copper and molybdenum concentrates by reprocessing tailings produced by the El Teniente mine, which is owned and operated by Codelco. MVC has the rights from Codelco to process the Fresh Tailings generated at the El Teniente mine.
