Metallurgical Processes

Biocidal inhibitors are not commonly used in marine corrosion control. Organic inhibitors, inorganic inhibitors, and metallic inhibitors are more commonly employed.

Graphite heat exchangers are resistant to corrosion and are commonly used in applications involving corrosive fluids. They are particularly suitable for handling highly acidic or alkaline solutions.

Refining is the process of extracting valuable materials from old mobile devices.

Die casting is a metal casting process where molten metal is forced into a die cavity under high pressure.

Enrichment is the process of separating fissile isotopes from non-fissile isotopes in uranium ore. This is done to increase the concentration of the fissile isotope uranium-235, which is used as fuel in nuclear reactors.

Crushing and grinding are essential steps in mineral processing to reduce the size of ores, liberate valuable minerals from gangue, and increase the surface area of minerals for subsequent processing.

Flotation is a process that separates minerals based on their surface properties. It involves adding chemicals to the mineral mixture, which selectively attach to the surfaces of valuable minerals. These minerals are then carried to the surface of the flotation cell by air bubbles, while gangue minerals remain suspended in the water.

Roasting is a process that involves heating ores in the presence of air to convert sulfide minerals to oxides. This process is often used to remove impurities and prepare ores for subsequent processing.

Leaching involves the use of chemical solutions to dissolve valuable minerals from ores. This process is commonly used for metals such as copper, zinc, and gold.

Smelting is a process that involves heating ores to high temperatures to melt and separate metals from impurities. This process is commonly used for metals such as iron, copper, and aluminum.

Beneficiation is a general term that refers to the processes used to improve the quality of ores by removing impurities, concentrating valuable minerals, and increasing the overall value of the ore.

Enrichment is the process of increasing the concentration of uranium-235 in uranium ore by removing uranium-238.

Smelting is a pyrometallurgical process that involves heating ores to high temperatures in the presence of oxygen to extract metals. This process is commonly used to extract metals such as iron, copper, and aluminum.

Cyanidation is a hydrometallurgical process that involves using cyanide solutions to dissolve metals from ores. This process is commonly used to extract gold and silver from ores.

Mechanical recycling is a process that involves melting and reshaping metal waste into new products. This method is commonly used to recycle metals such as aluminum, steel, and copper.
