Copper (Cu) Physiological role: Copper is an essential metal for plants. It plays significant roles in respiratory electron transport chains, in ethylene sensing, cell wall metabolism, oxidative stress protection and biogenesis of molybdenum cofactors. Copper is one of the micronutrients which is needed in very small quantities by plants.
There are 7 essential plant nutrient elements defined as micronutrients [boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)]. They constitute in total less than 1% of the dry weight of most plants. The following discussion focuses primarily on the soil characteristics for the micronutrients. a. Boron (B)

R.W. Kapp Jr., in Encyclopedia of Toxicology (Third Edition), 2014 Exposure and Exposure Monitoring. Molybdenum is an essential trace element for both animals and plants; hence, trace quantities of molybdenum are beneficial and perhaps essential for the normal growth and development of plants and animals. In mammals, molybdenum is a component of certain metalloflavoproteins, including …
4. sulfur-containing amino acids may alter copper utilization or molybdenum excretion 5. Animal species - cattle are more susceptible 6. Age - young animals are more susceptible, and excretion of molybdenum into milk may produce toxicoses in nursing calves 7. Season of year - molybdenum concentrations in plants increase in the fall 8.
Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.
The 240,000 tpd Cerro Verde Production Unit Expansion concentrator design is based on conventional copper sulfide flotation unit operations, replicating the C1 process but includes larger process equipment at a separate location on the mine property. The mine is an open-pit copper and molybdenum complex near Arequipa, in southern Peru.
At nameplate capacity, the plant will generate an additional revenue stream of about A$45 million per annum. Moly is extracted from the copper concentrate stream prior to it being pumped to Blayney, producing a Moly concentrate at Cadia that will be approximately 50% Molybdenum …
The copper concentrator produces 1050 mt/day of bulk Cu-Mo concentrate averaging 27% Cu and 0.6% Mo. Molybdenum plant feed is thickened to 62% solids and stored in two 150 cubic meter tanks. Two identical flotation circuits are fed from a constant head tank through changeable orifice plates thus maintaining steady feed rates.
Copper cathode comprised 38,400t, while copper in sulphate accounted for 4,600t. Copper concentrate production during 2011 was 178,800t. The mine also produced 948t of molybdenum concentrate during the year. The average copper production of the mine during the next ten years is expected to rise by 200 kilo tons per annum (ktpa).

The ore is crushed and transported on a 5.5-kilometre overland conveyor to a conventional flotation plant where copper concentrate is produced, then to a molybdenum plant for further processing. Concentrate is then transported by truck and rail to the Port of Matarani in the Arequipa region, where it is shipped to customers worldwide.
The Bagdad operation consists of an 81,600 metric ton-per-day concentrator that produces copper and molybdenum concentrate, a SX/EW plant that will produce approximately 5 million pounds per year of copper cathode from solution generated by low-grade stockpile leaching, and a pressure-leach plant to process molybdenum concentrate.
Molybdenum should be in the range of 0.002 - 0.006 mg% and reflects the cellular level of molybdenum. The ideal ratio of "copper to molybdenum" is 625. If it is lower, it can indicate a molybdenum deficiency relative to copper. Though this is not always the case.
It is a large scale operation, with a copper-molybdenum-gold sulphide mineral reserve of more than 1 billion tonnes, and a mine life of more than 20 years.

To treat a molybdenum deficiency in a plant, correct the pH level of the soil by reducing the acidity and apply a molybdenum fertilizer. Molybdenum is an element that is necessary for plant growth. When a plant is deficient in molybdenum, its leaves turn yellow or wilt, and its growth is stunted.
Plants also need small quantities of iron, manganese, zinc, copper, boron, and molybdenum, known as trace elements because only traces of them are needed by the plant. Macronutrients: The mineral elements are the plant nutrients which are required by the plants in large quantities (more than 1 ppm) are called macronutrients.
Plants require very small amounts of some essential elements. These micronutrients are often called minor or trace elements. These nutrients—boron, zinc, molybdenum, iron, manganese, copper, chlorine, and nickel—are needed for plant growth, development, and reproduction. Most Mississippi soils have enough of these nutrients for crop production.
All plants use molybdenum to make nitrogen into important compounds, including amino acids and chlorophyll. Natural Sources. Most soils naturally contain enough molybdenum to sustain plant life. However, seaweed extract is a good supplemental source of molybdenum. Deficiency. Molybdenum can be leached from sandy soils that receive too much ...
molybdenum additions. Excess molybdenum is more likely to be a problem with animals than with plants. Concentrations exceeding 10 ppm are not toxic to plants, but ruminants feeding on plants with this much molybdenum are apt to develop molybdenosis, an antagonism of molybdenum on copper metabolism. Dietary copper supplementation
