Molybdenum Market Quotes Comment
The external market: according to the external display quotes, recently, Western Europe, the United States and other Molybdenum crucible market prices are slight signs of recovery, molybdenum oxide, molybdenum oxide and other products have a certain price increases. According to external businesses, said an increase in demand due venue, driving prices up. However, investors are still difficult to judge the trend of late, we can expect that there will be no short-term price or downside. In addition, the molybdenum price increases in part to lag behind molybdenum products.
Internal Market: The current domestic market was slightly weaker molybdenum, transaction status no significant change. But business is still very strong psychological price. Failed to release the entire market demand, although some manufacturers offer of foreign higher, while the actual turnover is difficult, and the overall number of transactions is poor. Molybdenum miner relative shortage of supply, the price rise trend is still strong; molybdenum quote steadily rising steel trick to boost confidence in the business outlook; molybdenum deep processing factories increased production costs, while the terminal needs calm, so the operating pressure is relatively increased. Saddle Ridge is expected in the short term molybdenum prices will show a slight concussion trend.

many choose to watch the market
August 21 tungsten price 132,500 yuan / ton, the price index was 129.9 (2012-8-20,102000 yuan / ton), representing the lowest point of 100 cycles (2012-8-20) raised 29.9. Tungsten end demand for a long time has not been effectively improved, Minmetals month procurement plan has not been announced, businesses increasingly worried about the market, many choose to watch the market, at least temporarily operate or not operate.
Tungsten eletrode Market procurement needs too, thinly traded. According to sources, Minmetals last weekend asking the next miner inventory, consulted the next single, but in the meantime and not out of the acquisition plan, the latter will continue purchasing and storage is not clear. According to research, at present more than 60 degrees wool wolframite ore price 1.78 yuan / kWh nearby and procurement needs less; business confidence, traders are afraid to purchase tungsten, fearing heart harder shots. And due to lack of demand and financial pressure, cash transactions of small quantities of tungsten, the price even lower than the gross price is also mine. According to the analysis is expected this week, Minmetals if not taken any purchasing and storage plan, or tungsten concentrate prices this week due to lack of demand for support and fell again

August 23 was 129.9 concentrates index TCPI
August 23 tungsten carbide inserts price 132,500 yuan / ton, the price index was 129.9 (2012-8-20,102000 yuan / ton), representing the lowest point of 100 cycles (2012-8-20) raised 29.9. Our tungsten ore market turnover is expected next week will be difficult to have a big breakthrough in the overall market or continue steady weak.
Note: Cycle refers 2012-8-20 date, tungsten Index (Tungsten concentrate price index, TCPI) is the date 2012-8-20 price comparison with mainstream price formation relative number.
This week tungsten prices, demand continues to slump, business confidence. High production costs, demand remains in the doldrums, tungsten ore businesses survive in the cracks, abnormal operation carefully, the whole tungsten ore market is almost "priceless free city." Business mentality slightly differences, mainly in two ways.
The late part of the business that tungsten ore prices will remain high for two main reasons: a tungsten high production costs, which is the most significant reason, two tungsten itself rare attributes, three tungsten importance of the application of national policies or even more focus on tungsten.
Another part of the business that concentrates market continues down this is normal, if there is no demand for support, the latter may continue to fall until the market really go along with a reasonable price. Main reasons: First up is not the shortage of raw materials led so far this year are adequate overall inventory tungsten ore; two prices is not demand-driven, no actual downstream demand, the price of tungsten lack of support; three at home and abroad this year, the overall economic environment is not very good, to some extent restricted the tungsten demand; four bank loans difficult, costs increase; Fifth, some time ago, the actual purchase of tungsten ore is mainly Minmetals purchasing and storage. August 21 was 129.9 concentrates index TCPI

In molybdenum metallurgical production process, the chemical analysis of molybdenum occupies an important position, to study the characteristics of analytical chemistry is essential.
The chemical nature and characteristics of molybdenum
1.3.1 Properties Molybdenum [3,4]
Molybdenum in air at room temperature is stable; when the temperature at 400 ℃, minor oxidation (oxidized color can be seen); at 500 ~ 600 ℃, the metal molybdenum rapidly oxidized to MoO3; at 600 ~ 700 ℃, the molybdenum rapidly oxidized to MoO3 volatilization; higher than 700 ℃, the water vapor will strongly oxidized molybdenum MoO2.
Molybdenum up to its melting temperature and hydrogen will not be any chemical reaction. However, when heated in H2 molybdenum, can absorb some of the solid solution H2 generated, for example, at 1000 ℃, 100g 0.5cm3 molybdenum can only absorb hydrogen and fine particles at 300 ℃ molybdenum metal powder can absorb hydrogen.
Less than 1500 ℃, molybdenum and nitrogen does not react; higher than 1500 ℃, the molybdenum chemical reaction with nitrogen nitride. If the nitrogen pressure is low, to 2400 ℃ still do not see the reaction. The role of nitrogen and molybdenum, and nitrogen pressure and temperature related.
Molybdenum target valence of +2, +4 and +6 +6 stable price. Molybdenum is a transition element, easy to change the oxidation state of the redox reactions in the body plays a role in electron transfer. The oxidized form, the molybdenum is likely to be in the +6 state. Although the electron transfer during which it is also likely to be restored first +5 valence state, but after the restoration of the enzyme was also found in other molybdenum oxidation state.
Carbon, hydrocarbons and carbon monoxide, starting from 800 ℃, the interaction between the molybdenum and molybdenum carbide (Mo2C). Carbon dioxide at 700 ℃ or more, can make molybdenum oxide. Fluorine and molybdenum react rapidly at room temperature, 60 ℃ generate volatile fluorinated molybdenum MoF6, when the presence of oxygen to generate Mo2F2 or MoF4. Below 230 ℃, molybdenum on the drying chlorine has a strong corrosion resistance, 250 ℃ when the interaction between molybdenum and chlorine can; molybdenum susceptible to wet chlorine corrosion, generated with volatile molybdenum chloride MoCl5. Below 450 ℃, molybdenum on drying bromine has a strong corrosion resistance, temperature rises up to 550 ℃ or more, molybdenum reacts only with dry and bromine. Molybdenum in the air and wet bromine can react chemically.
Iodine and Mo in 500 ~ 800 ℃ due to the reaction.
When moisture is present, all the halogens are at room temperature for molybdenum work.
