Our main product is Ferro Molybdenum, Moly Oxide, and Molybdenum Concentrate. We are manufacturing over 10,000 tons of Moly Oxidize and 6000 tons of Ferro Molybdenum each year, which are mainly sold by exporting.
Molybdenum was discovered by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. The most important ore source of molybdenum is the mineral molybdenite a minor amount is recovered from the mineral wulfenite. Molybdenum commonly is recovered as a by product or co product from copper mining.Natural abundance The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide, and then reducing to the metal. The main mining areas are in the USA, China, Chile and Peru. Some molybdenum is obtained as a by product of tungsten and copper production. World production is around 200,000 tonnes per year.

The novel technology includes leaching molybdenum by air oxidation in alkaline solution，purifying the leach solution with freshly precipitated “nascent” Fe(OH) 3 and “buffer agent” NaHCO 3, enriching molybdenum by ion exchange and crystallizing ammonium molybdate tetrahydrate.

Molybdenum ores form under endogenous and exogenous conditions. Endogenous ores are related to skarn, greisen, and hydrothermal deposits. The major ore mineral in these deposits is molybdenite (MoS 2), which contains 60 percent molybdenum. Copper.
About Molybdenum ore Molybdenum ore weighs 1.6 gram per cubic centimeter or 1 600 kilogram per cubic meter, i.e. density of molybdenum ore is equal to 1 600 kg m . In Imperial or US customary measurement system, the density is equal to 99.88 pound per.The raw ore used in the experiment comes from a porphyry molybdenum deposit. Its’ main ore type is molybdenite. In the granite porphyry ore of the central part of the ore body, there’s a high content of molybdenite, with relatively uniform distribution and coarser particle size in the edge of the ore body and low grade ore, molybdenite has.
This map shows which countries export or import of Molybdenum Ore.Each country is colored based on the difference in exports and imports of Molybdenum Ore during 2019 In 2019, the countries that had a largest trade value in exports than in imports of Molybdenum Ore were Chile ($1.11B), Peru ($644M), United States ($561M), Mexico ($364M), and Canada ($94.1M).Of all the molybdenum producers, China produces the vast majority of the world’s supply by a large margin. The country’s molybdenum output remained the same from 2016 to 2017, at 130,000 MT.
Molybdenum mining and processing techniques have been improved continuously since the first mine was started at Climax near Leadville, Colorado in 1916.Today, the principal moly mines, both primary and by product, are found along the Great Continental Divide of the Americas, in China and in the CIS.The result shows that the grade of molybdenum ore concentrate is 45.31 , the recovery is 65.98 and the rich ore ratio reaches 20.59 by the regrinding and scrubbing seven cleaning, the regrinding of concentrations from middling of molybdenum sulfur separation. The regularly concentrated material from the apparatus was as the middling products.
A spill from a tailings dam at a molybdenum mine in northeast China on Saturday has contaminated water up to 110 km (68 miles) downstream, environmental authorities said on Wednesday. Tailings dams are commonly used by mining firms to store waste remnants of ore but they have come under close scrutiny since the collapse of one in Brazil last year killed than 250 people.The coarse molybdenum concentrate is reground in two or three stages, and the final molybdenum concentrate is obtained by four or five times of selection. The flotation reagent of molybdenum ore uses non polar oils as collectors, while adding foaming agents. The United States and Canada use the surfactant Syntex as an oil emulsifier.
