    Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. What is atomization process Atomization process involves use of high pressure fluid jets to break up a molten metal stream into very fine droplets, which when solidify into fine particles . Method was used on ....extraction efficiency by sintering the mixture of coal fly ash and concentrated sulfuric acid at 300 C to transform ... larger than that of other metal oxides in the coal fly ash. So, this coal fly ash is obviously suitable for producing aluminum sulfate or alumina oxide..The binders serve a critical purpose in forming the metal powder into a specific shape. However, they are ultimately sacrificial and must be selectively removed up to 4 before the green parts can be exposed to the high heat required for the next step of sintering. Fluid extraction of the binders is easily done with a vapor degreaser.

    US5985208A Process for debinding and sintering metal

    Metallurgy is defined as a process that is used for the extraction of metals in their pure form. The compounds of metals mixed with soil, limestone, sand, and rocks are known as minerals. Metals are commercially extracted from minerals at low cost and minimum effort. These minerals are known as ores. A substance which is added to the charge in ....Extraction and refining Roasting and sintering. Both of the main extraction methods for the production of zinc, electrolysis and smelting, require the prior removal of sulfur in a highly exothermic oxidation reaction. For the electrolytic production of zinc, the roasting of concentrates is achieved in fluidized-bed roasters, in which finely divided and heated particles of concentrate are ....a extraction of iron and other metal values from red mud using a pat-ented process, named as Elgai process, available for the removal of alu-minafrom iron ores and b use of red mud as an additive in the iron ore sintering. The second approach has particularly yielded interesting re-sults.
