Abstract

The Invention relates to a process for the milling of vegetable-based material, in particular plants like seeds, to produce dehulled or/and fractionate flour that includes a Material Bed Compression milling of the vegetable-based material. A first air classification of the milled material is performed to obtain a first fine fraction on one side and a first coarse fraction on the other side. A first post-treatment to the first fine fraction is then performed to obtain separate flour. The first coarse fraction is then recycled to the milling step.

Abstract

A method for continuous aeraulic separation of particulate materials consisting of a mixture of particles that is heterogeneous in both particle size and density is provided. The method includes grinding particles of materials, generating a gas stream conveying the ground particles, first aeraulic separation on the gas stream in order to separate the particles it contains into a first fraction consisting of the coarsest particles with variable densities and a second fraction consisting of the finest particles. A second aeraulic separation is performed on the first fraction in order to separate the particles that it contains into a third fraction consisting of the coarsest and/or most dense particles and a fourth fraction consisting of the least coarse and/or the least dense particles. A re-injecting of the third fraction or the fourth fraction at the inlet of the grinding is performed while simultaneous recovery of the second fraction as well as the fourth fraction or the third fraction, respectively, as output products.

Abstract

According to the invention, a method for treating electronic waste with a view to individually recovering metals included in such waste is provided. Said method is characterized in that it includes the series of the following steps: grinding the waste under conditions suitable for individually separating the different metal components of the waste; mixing the ground waste with a liquid such as to form a suspension; gravitationally separating the suspension such as to separate the particles having the highest densities and containing the majority of the metals from the particles having the lowest densities; and densimetrically separating the suspension containing the majority of the metals such as to obtain suspensions containing the individually separated metals.
