Sieving is a separation technique based on the difference in particle size. The sieve is responsible for retaining the larger particles. On top of size, other factors play a role in determining whether a particle will pass through the sieve or not; format of the particle whether the particle will fall where there is an opening or on the mesh of ...

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are …

Scrap material, having components which are rendered brittle by freezing, is passed through a freezing zone at cryogenic temperatures to make said components temporarily non-ductile. The scrap is then crushed in a first comminution zone to a relatively small size. Thereafter, the scrap is sorted by a first air separator into streams (a) ''''dust'''' or fines, (b) a light fraction and (c) a ...

Sodium carbonate and sodium hydroxide are also common ...

Biologically active molecules create substitutes in liquid water by forming single-domain ferroelectric crystallites. These nanoparticles are spherical and constitute growing chains. The dipoles are aligned, but can be set in oscillation at the frequency of vibration of the charged part of active molecules. They are then automatically trimmed and become information carriers.
