The Spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals which have a big enough specific gravity difference. Spiral chute principleRaise the spiral chute and fix it in the proper position, sand pump send the ore to the feed inlet, adding water to adjust the concentration of the slurry. The slurry naturally swirls from high to low and generates an inertial centrifugal force in the rotating bevel flow rate. The mineral is separated from the sand by the gravity and centrifugal force of the swirl by the difference in specific gravity, grain size and shape of the ore. The concentrate flows into the concentrate bucket and is connected by the pipeline. The tail sand flows into the tailing sand bucket and is connected to the sand pool by the pipeline, and then drained by the sand pump to complete the whole process of the beneficiation.

L'analyse du champ lectrique, l'aide de la mthode des lments finis, a t utilise pour la simulation numrique des trajectoires de particules dans les sparateurs lectrostatiques pour matriaux granulaires. Les expriences faites sur un lectrosparateur de recherche confirment partialement les hypthses de calcul, mais indiquent - en mme temps - la ncessit d'amliorer le modle mathmatique. Dans le but de dceler les phnomnes physiques spcifiques, les recherches prliminaires prsentes dans cet article ont t faites pour des configurations simplifies du champ lectrique. Les quations du mouvement d'une particle ont t crites dans le cas d'un champ mono-ionis uniforme, gnr entre deux lectrodes planes. On a dtermine, exprimentalement, le champ de dcollement des particules sphriques et cylindriques, dans des conditions diverses: champ harmonique, dcharge couronne entre lectrodes pointe plan, champ ionis entre lectrodes cylindriques coaxiales. L'analyse thorique et les donnes exprimentales ont mis en vidence la multitude des facteurs qui dterminent les mouvements des particules conductrices dans les champs couronne lectrostatiques des lectrosparateurs pour matriaux granulaires.

Electric field computation by means of the finite element method was employed for the numerical simulation of particle trajectories in the electroseparators for granular materials. The experiments, carried out on a laboratory electroseparator, partially confirmed the computational hypothesis. At the same time, they pointed out the necessity of improving the mathematical model. In order to reveal the specific physical phenomena, the preliminary researches presented in this paper were done on several simplified electric field configurations. Particle movement equations were written for a uniform mono-ionised electri field. The lift-off field of spherical and cylindrical particles was experimentally evaluated for different conditions: harmonic field, corona discharge between point-plate electrodes, mono-ionised field between coaxial cylindrical electrodes. The theoretical analysis and the experimental data pointed out the multitude of factors which determine the movements of conductive particles in corona-electrostatic fields of the electroseparators for mixed granular materials.
