The Haber process - Fertilisers - AQA - GCSE Chemistry

In the Haber process: nitrogen (extracted from the air) and hydrogen (obtained from natural gas) are pumped through pipes; the pressure. of the mixture of gases is increased to 200 atmospheres.

Why is iron used as a catalyst in Haber`s process? - Quora

(1) It works. Many other transition metal species have been tested in the Haber process and iron is among the best. (2) It is cheap. Iron is the most abundant transition metal in the earth’s surface. The Haber process is run at a collosal scale so

Processes - Gekko Systems

When separating free gold from a typical quartz deposit, gravity concentration must separate based on specific gravities of 19.3 and 2.6, for gold and quartz respectively. The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer.

Extracting Gold | HowStuffWorks

The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon.

Element information, properties and uses | Periodic Table - Argon

And no other process has ever induced argon to react - [a truly lazy element]. There are 50 trillion tonnes of argon swirling around in the Earth's atmosphere and this has slowly built-up over billions of years, almost all coming from the decay of the radioactive isotope potassium-40 which has a half-life of 12.7 billion years.

Haber’s Process | Facts, Definition, Conditions & Examples

According to this diagram, nitrogen gas is taken from the air. Then it is combined with hydrogen atom that is extracted from natural gas in the ratio of 1:3 by volume i.e. in this process the mixture of nitrogen and hydrogen is added in the reactor by the ratio of 1:3 means 1volume of nitrogen is going to be added with 3volumes of hydrogen. According to Avogadro’s Law during same temperature and pressure, an equal number of gases contains an equal number of molecules. These gases are thenallowed

Extraction of Aluminium (Aluminium Ore) - Hall-Heroults

Hall-Heroult Process. The Hall-Heroult process is widely used in the extraction of aluminium. In Hall-Heroults process, pure Al 2 O 3 is mixed with CaF 2 or Na 3 AlF 6. This results in lowering of the melting point of the mixture and increases its ability to conduct electricity. A steel vessel with the lining of carbon and graphite rods is used.
