Description
(54) СПОСОБ ОБОГАЩЕНИЯ ПОРОДУ(54) METHOD OF ENRICHMENT OF BREED
Изобретение относитс к обогащению полезных ископаемых, в частности к обогащению слабомагнитных руд.The invention relates to the beneficiation of minerals, in particular the enrichment of weakly magnetic ores.
Известен способ обогахцени слабомагнитных руд, включающий измельчение и магнитную сепарацию 1 .The known method ogahahtsen weakly magnetic ores, including grinding and magnetic separation 1.
Недостатком данного способа вл етс низка эффективность процесса магнитной сепарации.The disadvantage of this method is the low efficiency of the magnetic separation process.
Наиболее близким к изобретению по технической сущности и достигаегюму эффекту вл етс способ обогащени породы, включающий измельчение и обработку исходного материала веществами, усиливающими магнитную восприимчивость частиц, удал емых затем из исходного материала посредством магнитной сепарации 2J ,The closest to the invention to the technical essence and the achievable effect is a method of rock enrichment, including the grinding and processing of the source material with substances that increase the magnetic susceptibility of particles that are then removed from the source material by means of magnetic separation 2J,
Недостатком данного способа вл етс низка эффективность процесса разделени золотосодержащих руд.The disadvantage of this method is the low efficiency of the gold ore separation process.
Цель изобретени - повышение эффективности процесса магнитной сеПарации золотосодержащей руды.The purpose of the invention is to increase the efficiency of the process of magnetic separation of gold ore.
Эта цель достигаетс тем, что согласно способу обогащени породы обработку исходного материала осуществл ют карбонилом металла Шгруппы таблицы Менделеева при температуре до 250°С в течение не более 2ч.This goal is achieved by the fact that, according to the method of rock enrichment, the treatment of the source material is carried out by the carbonyl metal of the metal group of the periodic table at a temperature of up to 250 ° C for no more than 2 hours.
Обработку осуществл ют пентакарбонилом железа, карбонилом никел или карбонилом кобальта при 100-250с, преимущественно при 100-130 С в течение не более 0,5 ч.The treatment is carried out with iron pentacarbonyl, nickel carbonyl or cobalt carbonyl at 100-250 seconds, preferably at 100-130 ° C for no more than 0.5 hours.
Карбонил металла ТПГ группьр Менделеева ввод т в исходу1ый материал Carbonyl metal TPG group Mendeleev introduced into the end material
.10 в количестве 0,25-8 кг на 1 т исходного материала, преимущественно 0,54 кг на 1т, посредством инертного газа-носител ,.10 in the amount of 0.25-8 kg per 1 ton of starting material, preferably 0.54 kg per 1 ton, by means of an inert carrier gas,
Перед обработкой карбонилом ме15 талла VIII группы таблицы Менделеева провод т магнитную сепарацию исходного материала при этом на обработку направл ют немагнитную фракцию.Before treating the carbonyl metal of the metal of group VIII of the periodic table, magnetic separation of the starting material is carried out, while the non-magnetic fraction is directed to the processing.
Предложенный способ осуществл ют The proposed method is carried out
20 следующим образом.20 as follows.
Исходный материал, содержащий золото, подвергают измельчению и магнитной сепарации, причем немагнитный продукт направл5пот в реактор, The source material containing gold is subjected to grinding and magnetic separation, with the nonmagnetic product being directed to the reactor,
25 нагревают до 100-250°С и обрабатывают парами пентакарбонила железа Fe(CO)j подаваемыми в реактор посредством тока азота в течение нв . более 2 ч преимущественно не более.25 is heated to 100-250 ° C and treated with iron pentacarbonyl vapors Fe (CO) j fed to the reactor through a stream of nitrogen for nv. more than 2 hours, mostly no more.
