China Tungsten Market Analysis

The price of molybdenum concentrate, sodium molybdate and ammonium molybdate continues to be steady. Last week, domestic molybdenum market showed signs of recovering. Shipments in miners increased, trading volume is improved and molybdenum concentrate price remained strong. Biddings in the steel mills entered and ferromolybdenum price is expected to rise. As for molybdenum alloy and chemical market, markers are waiting the coming of heat reason to release the demand, and buyers are reluctant to sell. Overall, the supply and demand in the molybdenum market are improving. Insiders are generally optimistic about the performance of molybdenum prices in September. We suggest paying close attention to changes in fundamentals in the afternoon market.

Molybdenum Oxide Introduction

Molybdenum oxide is the chemical compound with the formula MoO3. It is a violet-colored solid and is a metallic conductor. It crystallizes in a monoclinic cell, and has a distorted rutile, (TiO2) crystal structure. In MoO2 the octahedra are distorted, the Mo atoms are off-centre, leading to alternating short and long Mo – Mo distances. The short Mo – Mo distance is 251 pm which is less than the Mo – Mo distance in the metal, 272.5 pm. The bond length is shorter than would be expected for a single bond. The bonding is complex and involves a localization of some of the Mo electrons in a conductance band accounting for the metallic conductivity.


The major use of roasted molybdenite concentrate is to add molybdenum to steel produced in the electric arc furnace.The material may be added to the charge or to the molten bath. For the adjustment of the final analysis, the use of roasted molybdenite concentrate is not recommended.

For optimum recovery the following should be observed. If added with the charge, the roasted molybdenite concentrate containing packages should always be covered with scrap or liquid metal. If added to the bath, the product should be introduced under the slag level. If used in the electric arc furnace, direct contact with the electrodes should be avoided.

Ultrafine α-molybdenum Oxide Production Process

Ultrafine α-molybdenum production process, including: the ammonium dissolved in the water, get molybdate supernatant; preparation of acetic acid, adding hydrogen peroxide, are acidic precipitation agent.

Heating reactor; same side of the precipitating agent slowly dropped into the acidified ammonium molybdate solution, while stirring, until the solution pH value of 3.0 to 4.0; filtering the reaction solution, get yellow - white precipitate, placed in drying oven, get massive molybdenum oxide, and then crushed and sieved to obtain molybdenum oxide meal.



Roasting; The jet mill to obtain ultrafine α-molybdenum powder.

Background of the invention solves the technical difficult to achieve large-scale production; of equipment, raw materials for high, easy to control the production process, or poor security, filtering difficult technical problems. Invention of cheap raw materials, easy to get, the production process, equipment is simple, low cost, high yield and product dispersion, high purity.

Molybdenum Disulfide Properties and Chemical Properties

Molybdenum disulfide properties are stable, so it is usually made into lubricants widely used in high temperature, low temperature and vacuum conditions, which is a good lubricant for various mechanical parts. It is a black solid powder, soapy feeling, odorless, hexagonal or orthorhombic system, with metallic luster and its properties is similar to graphite. Its physical and chemical properties are as follows: Physical properties: chemical formula: MoS2, melting point: 1185 ℃, density: 4.80g / cm3 (14 ℃), Mohs hardness: 1.0-1.5. Chemical properties are as follows: it will not dissolve in water, dilute acid and concentrated sulfuric acid, but soluble in hot sulfuric acid. In other acids, alkalis, solvents, petroleum, synthetic lubricants also will not dissolve.


Molybdenum disulfide (MoS2) is a kind of good solid lubricating material. It has excellent lubricity to the equipment under the conditions of high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum. It is usually as anti-friction agent, antiwear agent, extreme pressure agent and antioxygen used in aerospace industry (vacuum anti-radiation lubrication), automobile industry (fixer and parts), anti-seizure industry (mechanical industry) (general lubrication), mining industry, military industry, shipbuilding industry, heavy industry, bearing industry, gear industry and assembly industry. In addition, it can also be used as additives for various lubricants, manufacturing molybdenum compounds, catalytic hydrogenation desulfurization catalyst, gas storage materials, and photovoltaic materials and so on.

Ammonium Tetramolate Price

The latest price of molybdenum concentrate and ammonium tetramolate slightly recovers and ammonium tetramolate price is unchanged from previous session. After more than a week's adjustment, the market mentality becomes better, trading volume improves and price sees a steady recovery. The movement in the demand side needs to be followed.

Molybdenum Price Analysis – Aug. 24, 2017

International, molybdenum price is declined as the demand has not yet recovered. The price of international molybdenum oxide has been slipping recently, thus beginning to show a certain impact on the mentality of Chinese. Fortunately, the decline will not create great impact to the Chinese market for the present due to a limited number of transactions. As of last night, the international price of molybdenum oxide fell to 8.05-5.2 USD/lb, and the European molybdenum price dropped to 19.9-20.1 USD/kg.


In China, molybdenum market becomes more active with the increase of ferromolybdenum biddings in steel enterprises and more production in large-scale molybdenum ores. For molybdenum concentrate, its market confidence is picking up, downstream enterprises wants to buy more products, market enquiries and transactions gradually increased, driven by new transactions in large mining enterprises. Markers have different views for molybdenum market, bulk cargo market is still stable and ferromolybdenum biddings in steel enterprises continue to increase. Most large-scale production enterprises are optimistic about the market late. Molybdenum chemical and deep processing market shows active driven by the transactions of upstream enterprises. Enterprises gradually begin to offer and the transaction remains to be started.

The views of our website: with the heavier turnover of fine molybdenum ore, Chinese molybdenum raw material stabilizes gradually. The molybdenum market remains uncertain factors, raw material transactions increase and market appears to stabilize. Ferromolybdenum market also needs little to recover. Chemical deep processing market may rise prices in the future. The current domestic market for molybdenum may stabilize and in line for some consolidation.
