Production of Fine Tungsten Powder by Electrolytic ...
01/05/2012 · Tungsten, which possesses a high melting point (3695 K) and excellent mechanical properties, has been widely applied in mining, metallurgy, machinery, construction, armament industry and etc. 1 Generally, there are two kinds of tungsten ores consist in the earth crust, wolframite ((Fe/Mn)WO 4) and scheelite (CaWO 4), with a rough ratio of 30: present, a great majority of .
Electro Chemical Machining
4. Modelling of material removal rate Material removal rate (MRR) is an important characteristic to evaluate efficiency of a nontraditional machining process. In ECM, material removal takes place due to atomic dissolution of work material. Electrochemical dissolution is governed by Faraday's laws.
Hydrodesulfurization
Hydrodesulfurization (HDS) is a alytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultralowsulfur diesel, is to reduce the sulfur dioxide (SO 2) emissions that result from using those fuels ...
copper extraction and purifiion
Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution. Concentration of the copper(II) sulphate solution by solvent extraction.

extraction of titanium
Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.
