UN PROCEDIMIENTO PARA SEPARAR UNA MEZCLA DE PARTICULAS QUE TIENEN PROPIEDADES PARAMAGNETICAS SIMILARES PERO DIFERENTES |
摘要 |
<p>The present invention provides a process for separating a concentrate containing two or more minerals having substantially similar paramagnetic properties by treating the minerals particles with a dispersing agent so as to maintain the particles adequately dispersed during a subsequent magnetic separation step. Thus, in one embodiment of the present invention a method is provided for separating sulfide concentrate into at least two fractions. The process comprises obtaining a slurry of the sulfide minerals particles, adding a dispersing agent to the slurry so as to maintain the particles in the slurry dispersed during a subsequent magnetic separation step and thereafter passing the so dispersed particle slurry to a high gradient magnetic field whereby the more magnetic particles are retained within the field and the less magnetic particles pass therethrough thereby affecting separation.</p> |
