Description
Известны способы переработки полиметаллических руд по схеме коллективно-селективпой флотации дл разделепи коллективных медно-свинцовых концентратов, заключающийс в применении цианида. Однако применение цианида, вл ющегос сильным дом, вызывает необходимость очистки сточных вод.Methods are known for processing polymetallic ores according to the collective-selective flotation scheme for separating collective copper-lead concentrates, which involves the use of cyanide. However, the use of cyanide, which is a strong house, necessitates wastewater treatment.
Дл устранени этих недостатков в описываемом способе разделени медно-свинцовых концентратов в обрабатываемую пульпу в качестве реагента-подавител флотации свинцовых минералов добавл ют сополимеры акрилнитрила с акриловой кислотой, полученные полимеризацией смеси акрилнитрила и акриловой кислоты в мол рном отношении от 1:1 до 1:6. Из смеси приготовл ют 8%-ный раствор, к которому добавл ют инициаторы полимеризации, например персульфат кали 0,5% и гидросульфит натри в количестве 0,25% суммы мономеров. Раствор выдерживают при 30-40° в течение 12-20 час.To eliminate these drawbacks, copolymers of acrylonitrile with acrylic acid, obtained by polymerization of a mixture of acrylonitrile and acrylic acid in a molar ratio of 1: 1 to 1: 6, are added to the treated pulp as a reagent-suppressor for the flotation of lead minerals. . An 8% solution is prepared from the mixture, to which polymerization initiators are added, for example, potassium persulfate 0.5% and sodium hydrosulfite in an amount of 0.25% of the total monomers. The solution is maintained at 30-40 ° for 12-20 hours.
Авторы привод т результаты опробовани способа при разделении Зыр новского коллективного медно-свинцового концентрата при флотации в течение 5-8 мин (см. таблицу).The authors cite the results of testing the method in the separation of Zyrnovsky collective copper-lead concentrate during flotation for 5-8 min (see table).
Предмет изобретени Subject invention
Способ разделени коллективных медно-свинцовых концентратов с предварительной обработкой их сернистым натрием дл десорбции реагентов и последующей флотацией медных минералов, отличающийс тем, что, с целью устранени токсичности процесса, в обрабатываемую пульпу в качестве реагента-подавител флотации свинцовых минералов добавл ют сополимеры акрилнитрила с акриловой кислотой, полученные полимеризацией смеси акрилнитрила и акриловой кислоты в мол рном отнощении от 1 : 1 до 1 : 6.A method for separating collective copper-lead concentrates with pretreatment with sodium sulfide to desorb reagents and subsequent flotation of copper minerals, characterized in that copolymers of acrylnitrile and acrylic are added to the treated pulp as a reagent-suppressant for flotation of lead minerals acid, obtained by polymerization of a mixture of acrylonitrile and acrylic acid in a molar ratio of from 1: 1 to 1: 6.
