Fig 1. Separation of recombinant IGF-1 (M r 7600) from its ZZ fusion protein partner (M r 14 500) and uncleaved material.. When should I use analytical SEC? Analytical SEC is a very effective method for protein analysis as it allows size profiling of protein samples due to the mild separation conditions that can be used to obtain high-resolution separations.
The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because ...
GRAVITY SEPARATION WHY USE GRAVITY SEPARATION? Gravity separation is the most well-proven and accepted technique of concentrating minerals and has been used as a primary form of mineral concentration for centuries. Due to its high efficiency and low cost, gravity separation is always the first consideration in any flowsheet development program and
How Does a Separator Work? A disk stack separator is based on the basic principle of sedimentation. In a solid/liquid mixture, the heavy solids collect on the bottom of the container. They sink due to gravity. (1) In a continuous solid/liquid separation system, not all the solid particles have sufficient time to settle on the bottom.
Separation through sedimentation could be done naturally with the earth gravity, nevertheless, it would take ages. Centrifugation is making that natural process much faster. Rotation of the rotor about a central axis generates a centrifugal force upon the particles in the suspension. Which factors have an influence on centrifugation :
Cyclone separators work much like a centrifuge, but with a continuous feed of dirty air. In a cyclone separator, dirty flue gas is fed into a chamber. The inside of the chamber creates a spiral vortex, similar to a tornado. This spiral formation and the separation is shown in Figure 2.

Gravity Separation Technology for Oil Sands. By Steve Fiscor, Editor-in-Chief. This year, the synthetic crude producers in Alberta predict that they will average 721,000 barrels per day, which amounts to mining 1.4 million tons per day of oil sands. This figure is expected to double in the next 10 to 15 years.
How Does it Work? After wastewater passes through filters to separate out the largest solids, it is funneled into the oil water separator to undergo treatment. In most cases, the wastewater travels across a series of plates, generally on an incline. These plates help to separate oil, water, and sludge into three distinct spaces.
Giant centrifuging machines are used in water treatment, where it spins the mud and sludge out of the water to produce cleaner water. Likewise, solid matter is separated from freshly drilled-out petroleum in oil rigs. Moreover, big spinning wheels are used to simulate a high-gravity environment to practice for the pilots.

Gravity separators, or air tables, separate particles with very close specific gravities. The particles are fed onto a large, slotted deck that is tilted slightly, as shown here. The deck vibrates and fans force air upward.
Continuous separation by gravity. A simple vessel which can be used for continuous separation of particles of non-uniform diameter from a liquid is shown in Figure 6.2.8. The liquid containing the slurried particles is introduced at one end of the vessel and flows towards an overflow outlet at the other end at a certain capacity.
