(5) СПОСОБ МАГНИТНОЙ ОБРАБОТКИ МИНЕРАЛЬНЫХ СУСПЕНЗИЙ ПЕРЕД ПРОЦЕССАМИ ФЛОТАЦИИ И ФИЛЬТРАЦИИ(5) METHOD OF MAGNETIC TREATMENT OF MINERAL SUSPENSIONS BEFORE FLOTATION AND FILTRATION PROCESSES
Изобретение относитс к обогащению полезных ископаемых. способ магнитной обработ ки минеральных суспензий, включающий обработку суспензии магнитным полем Известен также способ магнитной о работки минеральных суспензий перед процессами флотации и фильтрации, включающий воздействие на суспензию магнитным полем, направленным перпен дикул рно потоку суспензии 2J . Недостаток известных способов низка последующа эффективность про цессов флотации и фильтрации. Цель изобретени - повышение эффективности последующих процессов флотации и фильтрации. Указанна цель достигаетс тем, что в зоне воздействи магнитного по л провод т осаждени частиц суспензии под действием силы т жести. Предлагаемый способ осуществл етс следующим образом. Определ ют скорость осаждени минеральных частиц в суспензии под-дей . ствием силы т жести. Минеральную суспензию крупностью 0,1-0,02 мм направл ют в установленный наклонно желоб, в днище которого выполнены щели, причем стенками желоба. вл ютс полюса магнитов. Скорость перемещени суспензии по желобу устанавливают в два раза меньше скорости перемещени частиц под действием силы т жести. Напр женность магнитного пол составл ет 250-300 Э. Двига сь по желобу, минеральные частицы попадают в щели днища желоба, где падают под действием силы т жести, при этом нескомпенсированкые зар ды двойного электрического сло , имеющегос на границех двух фаз (жидкость-частицы), диффундируют в объем жидкости. Это приводит к уменьшению потенциала на поверхности частиц, возрастанию их гидрофобности и, следовательно, к повьшению эффективности последую-This invention relates to the beneficiation of minerals. Method of magnetic processing of mineral suspensions, including treating the suspension with a magnetic field. A method of magnetic processing of mineral suspensions before flotation and filtration processes is also known, including the effect on the suspension of a magnetic field directed perpendicular to the flow of the suspension 2J. A disadvantage of the known methods is low follow-up efficiency of the flotation and filtration processes. The purpose of the invention is to increase the efficiency of subsequent flotation and filtration processes. This goal is achieved by the fact that in the zone of action of a magnetic field, sediment particles are deposited by gravity. The proposed method is carried out as follows. The deposition rate of the mineral particles in the suspension of the sub-day is determined. the force of the power of the tin. The mineral suspension with a particle size of 0.1-0.02 mm is directed to an inclined chute, in the bottom of which gaps are made, with the walls of the chute. are the poles of magnets. The speed of movement of the suspension along the chute is set half the speed of movement of the particles under the force of gravity. The magnetic field intensity is 250-300 E. Moving along the chute, mineral particles fall into the slots of the bottom of the chute, where they fall under the force of gravity, while the uncompensated charges of the electric double layer at the boundary of the two phases (liquid-particle ), diffuse into the liquid. This leads to a decrease in the potential on the surface of the particles, an increase in their hydrophobicity and, consequently, to an increase in the efficiency of the subsequent
