Optimisation of magnetic separation: A case study for soil washing at

The magnetic study provided valuable information for the exhaustive explanation of the operation, and the deduced mathematical expression was found to be appropriate to estimate the performance of the separation operation. From these results we determined that magnetic soil washing was effective for the treatment of

Study on magnetic separation for decontamination of cesium

We examined the possibility of applying magnetic separation method using the superconducting magnet, which can process a large amount of the soil in high speed, to the soil decontamination and volume reduction of the radioactive cesium contaminated soil. Clay minerals are classified as 2:1 and 1:1 types by the 

Magnetic separation and evaluation of magnetization of Brazilian

Ten selected Brazilian soils representative of Oxisols, Ultisols, Alfisols and Inceptisols and derived from gneiss, basalt, sandstone, diabase and itabirite were sampled and examined to provide insight into the behavior of their magnetic minerals. The objective was to measure the magnetization of the sand, silt and clay

Separation Federal Remediation Technologies Roundtable

Magnetic separation is used to extract slightly magnetic radioactive particles from host materials such as water, soil, or air. All uranium and plutonium compounds are slightly magnetic while most host materials are nonmagnetic. The process operates by passing contaminated fluid or slurry through a magnetized volume.

Vibratory Sieves Magnetic Separators

This fully stainless steel magnetic separator is designed to provide the ultimate solution for controlling ferrous contamination when check screening dry powders. Unlike conventional magnetic separators where the magnetic bars are secured at both ends, the EasyClean Magnetic Separator™ has a unique openended 

USE OF HIGH GRADIENT MAGNETIC SEPARATION IN DETAILED

High gradient magnetic separation is a simple, inexpensive, nondestructive and rapid means of concentrating ironbearing minerals to nearly monomineralic levels, particularly those present in undetectable proportions in soil clays. The use of variable magnetic flux density further allows subfractionation of the ironbearing 

highgradient magnetic separation (hgms) in soil clay mineral studies

ABSTRACT: A modified HGMS system is described in which the inclusion of a peristaltic pump to continuously circulate a suspension of a soil clay through the magnetic trap greatly facilitates the operation of the technique. Appliion of this purely physical method of mineral separation to a variety of soil claysusing IR

Heavy Metal Removal from Soils Using Magnetic Separation: 1

The removal of Cu, Zn, and Cd from a sandy soil was investigated using iron filings as an adsorbent, and subsequently recovering the iron filings by magnetic separation. The best treatment was obtained by using 5% iron filings and 3 h contact time between iron filings and the soil. The metal removal efficiency from soil 

SolidPhase Separation

0. Magnetic Separation. In magnetic separation, a magnetized medium such as magnetized steel wool is used to separate slightly magnetic radioactive particles from soil. All uranium and plutonium compounds are slightly magnetic while most soil is nonmagnetic. Soil is mixed with water to form a slurry, and the slurry is 

CrPolluted Soil Studied by High Gradient Magnetic Separation and

Dec 1, 1998 It is demonstrated that such a combination is a powerful tool for the characterization of polluted soils, especially in cases where the pollution is present as discrete particles. Both EPMA and magnetic separation data indied that the Cr pollution was present as a hydrous Croxide phase. The Cr does not
