Test Procedure for the determination of the magnetic properties of ferromagnetic Powder

摘要

Test Procedure for the determination of the magnetic properties of ferromagnetic Powders used in dense Masses murky to separate Minerals by Flotation Treatment of Sinking. The ferromagnetic Powder is MAGNETIZED in a Magnetic Field continuio, with Field Strengths between 600 and 1000 / cm.To continuacionse diesminuye their magnetization in an Alternating Magnetic Field intensities, with Camo ranging between 1000 and 1500 / cm. Accumulates between 0.2 and 0.5 g of the Powder treated and disposed in the center of a plate (2) of Dielectric material.
