Description

Обессеривание высокосернистых и многозольных каменных и бурых углей и их концентратов с повышенным содержанием серы осуществл етс  химическими способами обогапшни  отсадкой и флотацией.The desulfurization of high-sulfur and multi-ash black and brown coals and their concentrates with a high sulfur content is carried out by chemical methods using a jigging and flotation process.

Однако указанные способы не обеспечивают полного удалени  пиритной серы.However, these methods do not ensure complete removal of pyrite sulfur.

Дл  наиболее полного удалени  серы пред.лагаетс , сог.пасно изобретению , смачивать ме. уголь или угольный концентрат слабыми химическими окислител ми, равноионными 0,5%-ному раствору перекиси водорода, высушивать при температуре до 100°, а затем подвергать магнитной сепарации в сильном поле.For the most complete removal of sulfur, it is proposed, according to the invention, to wet the IU. coal or coal concentrate with weak chemical oxidizing agents, equi-ionic with a 0.5% hydrogen peroxide solution, dried at a temperature of up to 100 ° and then subjected to magnetic separation in a strong field.

Сущность описываемого способа состоит в том, что мелкий уго.ль подвергаетс кратковременномуThe essence of the described method is that a shallow hull is subjected to a short-term

смачиванию слабыми химическими окислител ми, при котором на поверхности пиритнь х зерен и их сростков с породой и углем образуютс  сульфатные соединени  железа, обладающие магнитными свойствами. Обработанный уголь подвергаетс  затем кратковременной тепловойwetting with weak chemical oxidizers, in which sulfate iron compounds with magnetic properties are formed on the surface of pyrite grains and their intergrowths with rock and coal. The treated coal is then subjected to a brief thermal

подсущке при температуре примерно 100°.sub-network at a temperature of about 100 °.

При магнитной сепарации такого угл  в магнитный продукт выдел етс  основна  сера, св занна  с пиритом, а остаетс  малосернистый и малозольный угольный концентрат .In the magnetic separation of such coal, the basic sulfur associated with pyrite is released into the magnetic product, and low-sulfur and low-ash coal concentrate remains.

При использовании предлагаемого способа магнитную пленку необходимо создавать только на поверхности пиритных зерен, что обуславливает сравнительно небольшой расход окислителей и малую длительность процесса.When using the proposed method, the magnetic film must be created only on the surface of the pyrite grains, which causes a relatively small consumption of oxidizing agents and a short duration of the process.

Способ обессеривани  углей и угольных концентратов с применением магнитной сепарации, о т л ичающийс  тем, что, с целью боjree полного удалени  пиритцой серы , мелкий уголь или угольный концентрат смачиваетс  слабыми химическими окислител ми, равноценными 0,5%-ному раствору перекиси водорода, высушиваетс  при температуре до 100°, а затем подвергаетс  магнитной сепарации в сильном поле.The method of desulfurizing coal and coal concentrates using magnetic separation, which is so that in order to completely remove sulfur by pyrite, the small coal or coal concentrate is moistened with weak chemical oxidizers equivalent to 0.5% hydrogen peroxide solution, dried at temperatures up to 100 ° C, and then undergoes magnetic separation in a strong field.
