The goal is to improve the quality of products by reducing their sulfur, phosphorus and arsenic content.

Description
Изобретение относитс к обогащению полезных ископаемых дл удалени вредных примесей при разделении различного минерального сырь по плотности и может быть использовано дл обогащени угл , а также других материалов . The invention relates to the enrichment of minerals to remove harmful impurities in the separation of various mineral raw materials in terms of density and can be used to enrich coal as well as other materials.
Цель изобретени - повышение качества продуктов за счет снижени в них содержани серы, фосфора и мышь ка .The purpose of the invention is to improve the quality of products by reducing the content of sulfur, phosphorus and arsenic in them.
Способ включает обработку материала в щелочной среде при повышенной температуре, при этом в качестве щелочной среды используют активирован- 1гую воду с концентрацией иона Н не более , а температуру среды берут в пределах 20-ЮО°С. Обогащение осуществл ют одновременно с разделением по плотности в потоке активированной воды, а в качестве обогатительных устройств используетс двухсту- пенчата отсадочна мащина.The method involves treating the material in an alkaline medium at elevated temperature, while activated water with an H ion concentration of no more is used as the alkaline medium, and the medium temperature is taken within 20 ° C ° C. The enrichment is carried out simultaneously with the separation by density in the stream of activated water, and a two-stage jigging machine is used as enrichment devices.
Активированна вода полностью удовлетвор ет технологическим требовани м, предъ вл емым к разделительным средам. Молекула ее состоит только из атомов водорода и кислорода, т.е. не загр зн ет продукты разделени . Экологически безопасна, так как вода вл етс естественным компонентом земной атмосферы и относитс к группе невоспламен ющихс веществ.The activated water fully satisfies the technological requirements of the separation media. Its molecule consists only of atoms of hydrogen and oxygen, i.e. does not contaminate separation products. Ecologically safe, as water is a natural component of the earth's atmosphere and belongs to the group of non-flammable substances.

Воду используют из отстойников, в которых она находитс при 50-70 С, после оборотного цикла с добавкой свежей воды дл восполнени потерь. Активируют воду в электролизерах, а подогревают в специальных резервуарах . При активировании воды в электрлизере происход т следующие реакции:Water is used from sedimentation tanks in which it is at 50-70 ° C, after a circulating cycle with the addition of fresh water to compensate for losses. Activate the water in the electrolyzers, and heated in special tanks. When water is activated in an electricizer, the following reactions occur:
2Н,0+2е - Н,+20Н(катод);2H, 0 + 2e - H, + 20H (cathode);
2HzO-4e .Ог+4Н 2HzO-4e. Oh + 4H
(анод).(anode).
.Известно, что фосфор в полезных ископаемых (в частности, угл х и рудах ) существует в основном как неорганическое соединение с щелочными и щелочноземельными металлами. Сера существует в виде элементарной мелкозернистой серы, органических и неорганических соединений. При обработке вещества активированной водой мел кодисперсна свободна сера в водном растворе реагирует с гидроксилионом даже при комнатной температуре с образованием полисульфидов и тиосуль- фатов, при этом эффективность процес са при нагреве воды от 20 до 100°С возрастает.. It is known that phosphorus in minerals (in particular, coal and ores) exists mainly as an inorganic compound with alkali and alkaline earth metals. Sulfur exists in the form of elemental fine-grained sulfur, organic and inorganic compounds. When a substance is treated with activated water, chalk, a co-dispersed free sulfur in an aqueous solution reacts with hydroxy- ion even at room temperature with the formation of polysulfides and thiosulfates, and the efficiency of the process when water is heated from 20 to 100 ° C increases.
Кроме того, при воздействии Н и ОН ионов происходит гидролитическое расщепление сульфидов и полисульфидов с выделением элементарной серы в раствор,что наблюдалось визуально на практике. При выведении фосфора из углей основными продуктами реакции вл ютс фосфин (РНд) и кислота (HjPO.j). .Нижний предел активиции выбран , так как при менее низкой концентрации иона (Н) десульфураци и дефосфоризаци резко снижаютс .In addition, when exposed to H and OH ions, hydrolytic decomposition of sulphides and polysulphides occurs with the release of elemental sulfur into the solution, which was observed visually in practice. When phosphorus is removed from coal, the main products of the reaction are phosphine (pH) and acid (HjPO.j). The lower activation limit was chosen, since desulfurization and dephosphorization decrease sharply at a lower ion concentration (H).
