Extraction Molybdenum Methods from Tungsten Molybdenum Mixture and Mixture of Molybdenum and Other Metals

This article will describes some simple methods to extract molybdenum from tungsten molybdenum mixture and mixture of molybdenum and other metals. Extracted molybdenum from tungsten molybdenum ore is research focus of molybdenum extraction, the following will simple introduce some methods of separation tungsten and molybdenum and extracting molybdenum.

1. Recovering tungsten and molybdenum from phosphorus ore: the phosphorus ore was decomposed by 2~5mol/L acid, after that, to process liquid-solid separation, thereby separating the molybdenum and tungsten.

2. Separated tungsten and molybdenum from the mixed solution of tungstate and molybdate: to adjust tungstate and molybdate mixture’s pH value, and then added the precipitating agent so that it will reacts preferentially with the tungsten to produce precipitate. After solid-liquid separation can obtain molybdate solution and rich-tungsten slag.

3. Using tungsten hydrometallurgy to separate tungsten and molybdenum from mixed ammonium salt solution of tungsten and molybdenum: the vulcanizing agent is added to tungsten and molybdenum mixed ammonium solution and after reaction be processed thiosulfate treatment.

4. Depth Separated molybdenum and tungsten from mixture solution containing high content molybdenum and tungsten: Firstly, the pH was adjusted to 6.5~8.5, and then using exchange column of alkalescence anionexchange resin exchange resin to adsorb so that it can separate tungsten and molybdenum.

Several methods of extracted molybdenum from mixture of molybdenum and other metals are as follows:

1. Recovered molybdenum form aluminium base containing molybdenum waste slag: mixing aluminium base with NaOH solution and Na2CO3 evenly and then it be sintered in rotary kiln. After that it was digested by alkaline correction liquor, solid-liquid separation to obtain a crude liquid sodium aluminate and red mud residue. Finally, using resin adsorbs molybdenum in circulating mother liquor of Bayer liquor production system, thereby recovering molybdenum.

2. Extracted molybdenum from molybdenum copper mixture: heating molybdenum copper mixture form the molten matte to molybdenum copper matte. Add bubbling air or oxygen-enriched air into copper molybdenum matte for blowing, then after collecting dust in recovering MoO3.

Tungsten and Molybdenum with Sapphire

For the past 15 years single crystal sapphire has been at the cutting edge of semiconductor technology.

A combination of unique chemical, physical, optical and mechanical properties make sapphire the best choice for a broad spectrum.

•  Chemical resistance.
Sapphire is highly inert and resistant to attack in most process environments including hydrofluoric acid and the fluorine plasma applications commonly found in semiconductor wafer processing (NF3, CF4).

• Mechanical properties.
Sapphire is characterized by high toughness and solidity, and demonstrates excellent resistance in different environments ranging from cryogenic to over 1500°C. Due to this characteristics combined with chemical stability sapphire is widely used in medicine: endoscope and probe lenses, needles for thermal treatment of tumors, scalpels etc.

• Electrical properties.
Sapphire provides a high, stable dielectric constant with the electrical insulation required for LED, RF and microwave applications.

• Optical transmission.
Sapphire is characterized by high transmission in the range of UV to near IR. Given the chemical stability, high temperature and high pressure resistance sapphire is the preferred choice for window / viewport applications in high performance vacuum systems, furnaces, deep sea cameras, fire alarm systems etc.

• Surface properties.
Sapphire can be polished to very high flatness and smoothness for substrate applications and precision mechanical components.

• Thermal properties.
With a melting point over 2000°C, and high thermal conductivity sapphire is often used in many harsh process environments.

• Wear properties.
With high hardness and transparency, sapphire is used for scratch proof windows in high wear applications and for precision mechanical components.

Tungsten and Molybdenum Furnace Components

What is tungsten and molybdenum furnace components?

Tungsten has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Molybdenum also belongs to the refractory metals group with excellent thermal properties and is still easy to machine. So, tungsten, molybdenum and their alloy are the best choices for the all kinds of high temperature furnace. They can easily withstand even the most intense heat.
