One of the reasons ...
01/11/1994 · Abstract. High Gradient Magnetic Separation (HGMS) is a form of magnetic separation used to separate solids from other solids, liquids or gases. HGMS uses large magnetic field gradients to separate ferromagnetic and paramagnetic particles from diamagnetic host materials. The technology relies only on physical properties, and therefore separations can be achieved while producing a .
01/07/1999 · Abstract. Magnetic separation is a process for separation the magnetic material from nonmagnetic ones. The authors suggest that the Hancock equation is more suitable as an index for evaluating the performance of magnetic process. Several different cases are analyzed on the basis of different or same feed magnetic material content and different or same concentration and tailing magnetic ...

Abstract The ability to enrich cells with targeted mutations greatly facilitates the process of using engineered nucleases, including zincfinger nucleases and transcription activatorlike effector nucleases, to construct such cells. We previously used surrogate reporters to enrich ...
Abstract. Magnetic separation employs the difference in magnetic properties of minerals to effect separation between them. The magnetic separation may be for removing ore particles which are magnetic or conversely to remove magnetic impurities from a product which is nonmagnetic. Examples are Magnetite from Quartz or Magnetite and Wolframite from Cassiterite Topics: Minerals and Mining ...

First there will be a generalized introduction to relevant aspects of magnetism, magnetic susceptibilities, and magnetochemistry. Then follows a short account of the fundamentals of electrochemistry, followed by a development of the various magnetic .
The principle of operation of magnetic separation devices is the interaction between magnetic forces and competing gravitational, hydrodynamic, and interparticle forces within the magnetic separator. Without resort to a detailed analysis of the separation process, an understanding of the characteristics of magnetic separators is possible by consideration of a simple forcebalance model ...
24/08/2004 · Abstract: We have developed a high gradient magnetic separation (HGMS) system to remove arsenic from geothermal water and to supply hot water for public use by using a superconducting magnet. We attained the reduction of arsenic concentration to mg/L that is less than the standard for discharge of mg/L and slightly larger than the environmental standard of mg/L in Japan.
