Introduction to Bacterial Metallurgy
Bacterial Metallurgy
Bacterial metallurgy is a type of metal extraction process that utilises bacteria to break down metallic compounds and isolate the metal from its ore. This process reduces the use of toxic chemicals, minimises energy, and has the potential to make more efficient use of ore an......

Powder metallurgy sintering furnace
Powder Metallurgy Sintering Furnace
Powder metallurgy sintering furnaces are the most important part of the powder metallurgy process, used to harden and strengthen the structural parts made of powder metals. The powder metallurgy sintering furnace is a type of furnace used to heat the powder met......
Sintering
Sintering and Roasting
Sintering and roasting are two different processes used in metallurgy, a branch of applied science that deals with transforming metals from their natural state in to useful and usable objects. These processes are very important in metallurgical processes and are used to red......
soaking furnace
Induction heating is a process where electric current is passed through an electrical coil to create an oscillating electric and magnetic field. This magnetic field is used to heat a workpiece made from ferromagnetic material.
Induction heating has been used as a cost effective, accurate and eff......
ion exchange column
Ion Exchange Columns
Ion exchange is a process that occurs when one ion in a solution is exchanged for another ion of similar properties. This process can be very useful in a variety of industries, from water purification to chemical processing. If a solution needs to be purified of specific ions......
Melting furnace
Induction Melting Furnace
An induction melting furnace is a specialized piece of equipment designed to liquefy metals via uniform heating. The working principle behind induction melting involves transporting a newly charged energy source, usually consisting of high-frequency alternating current, ......

The Making of an Underground Furnace Vault
Underground furnace vaults are a unique engineering feat that is used for the storage and transport of natural gas, oil and other combustible fuels. The vaults comprise two kinds of components; the fire brick lining, and the underground chamber. The fire......
Cyanidation of steel
Stainless Steel Cyanidation
Cyanidation is the process of using cyanide to chemically leach gold from mined ore or rock. Cyanide-based solutions have been used for over a century to extract precious metals from gold ore. Cyanidation is sometimes referred to as the Heap Leach Process” due to its ......

Glow Obtained: Changes in Luminescence
Luminescence, or the emission of light, is an interesting property of many materials. Certain physical and chemical changes can cause the luminescence of certain substances to change dramatically. This phenomenon is especially prevalent in certain types of g......
foil rolling
Aluminum Foil Rolling
Aluminum foil rolling is a process that involves taking a block of aluminum and rolling it out until it forms a thin, flat sheet. This can be done manually or by specialized industrial machinery. Aluminum foil is most commonly used for packaging food, wrapping food, and crea......
