Description
Известный способ определени содержани лопарита в концентратах пр мым взвешнванием после отделени его механическим путем от сопутствзющих минералов пустой породы малопроизводителен.The known method of determining the content of loparite in concentrates by direct weighing after separation of the waste rock by mechanical means from the accompanying minerals is inefficient.
Особенностью предлагаемого способа вл етс спекание исходных лопаритовых концентратов с кальцинированной содой при температуре около 650. Это обеспечивает разложение сопутствующих минералов .A feature of the proposed method is the sintering of the original loparite concentrates with soda ash at a temperature of about 650. This ensures the decomposition of the accompanying minerals.
Кальцинированна сода при температуре около 650 разрзшает эгирин и другие минералы пустой породы (апатит, нефелин н др.), а лопарит остаетс нетронутым. Кремнекислота силикатов переходит в раствор последующим выщелачиванием 5%-ным раствором едкого натра.Soda ash at a temperature of about 650 breaks down the aegirine and other waste minerals (apatite, nepheline, etc.), and the loparite remains intact. The silicic acid of silicates goes into solution by subsequent leaching with 5% sodium hydroxide solution.
Гидраты железа удал ютс сол ной кислотой. Оставщийс лонарит после прокаливапи взвещиваетс .Iron hydrates are removed with hydrochloric acid. The remaining lonarite after calcination is cried.
Навеска измельченного (пор дка 200 меш) концентрата в 1 грамм тщательно растираетс с кальцинированной содой (0,2-0,3 г). Смесь переноситс в платиновый тигель. Тигель закрываетс крыщкой и ста-.A weight of ground (about 200 mesh) concentrate in 1 gram is thoroughly ground with soda ash (0.2-0.3 g). The mixture is transferred to a platinum crucible. The crucible is closed with a cap and a stack.
Еитс в разогретую (около 650°) муфельную печь. Через 2 часа спекание заканчиваетс . Спекща с масса переноситс в химический стакан на 150-200 мл и заливаетс 25 мл 5%-го раствора едкого натра и слабо кип титс 10 минут. После разбавлени 50 мл воды осадок лопарита и гидрата железа отфильтровываетс и промываетс 6-7 раз гор чей 10%-ной сол ной кислотой , а затем 4-5 раз гор чей водой. Фн.чьтр с осадком помещаетс в тот же тиге,1)Ь, сушитс и озол етс при 600-650. После охлаждени в эксикаторе лопарит взвенп-)ваетс .Eits into a preheated (about 650 °) muffle furnace. After 2 hours, sintering is completed. Batching the mass is transferred to a 150-200 ml beaker and filled with 25 ml of 5% sodium hydroxide solution and boiled gently for 10 minutes. After diluting with 50 ml of water, the precipitate of loparite and iron hydrate is filtered and washed 6-7 times with hot 10% hydrochloric acid, and then 4-5 times with hot water. The f.htr with sediment is placed in the same crucible, 1) b, dried and ozone at 600-650. After cooling in a desiccator, the vane is charged.
Предмет изобретени Subject invention
Способ определени содержани минерала лопарита в лопаритовых концентратах пр мым взвешиванием после отделени его химическим путем от сопутствующих минералов и пустой породы, отличающийс тем, что, с целью разложени сопутствующих минералов, 1 сходные лопаритовые концентраты спекаютс с кальцинированной содой при температуре около 650.The method of determining the content of the loparite mineral in loparite concentrates by direct weighing after chemical separation from the accompanying minerals and waste rock, characterized in that, in order to decompose the associated minerals, 1 similar loparite concentrates are sintered with soda ash at about 650.
