Description
(54) СПОСОБ ПЕРЕРАБОТКИ ФАЙНШТЕЙНА ты от 80 до 200 г/л (предпочтительно 190 г/л) и оол .ной кислоты - от 60 до 120 г/л (предпочтительпо 80 г/л). Обща кислотность смеси 3,8-4,2 г-экв/л обеспечивает получение .конечного раствора после первой стадии выщ.елачив,а,ни с содержанием .никел 100- ПО т/Л. Отфильтрованный р.аствор после второй стадии направл ют в первую стадию выщел.ачивани дл снижени свободной кислотности и одновременного пополнени никелем за счет растворени свежего файнштейна при продувке пульпы воздухО:М. Сульфидный остаток п-осле второй стади , содержащий, %: медь 72, ликель 0,4-0,5, кобальт 0,02-0,04, железо 2,5-3,5, сера 22-24, в дальнейшем перерабатывают по одному из известных сп1особов, например растворением в автоклавах с последующим восстановлением меди водородом или электроосаждением. Обе стадии выщелачивани провод т при температуре ниже точки кипени раствора (желательно 90°С) и отношении Ж:Т(3- -5) : 1. Врем выщелачивани на каждой из стадий составл ет от 1 до 1,5 час. На обеих стади х выщелачивани раствор насыщен сероводородом, благодар чему благородные металлы полностью переход т в сульфидный медный продукт. Расход тока на операции выщелачивани с наложением посто нного тока составл ет -около 450 КВТ на 1 т никел , перешедшего ;в раствор . Извлечение металлов в раствор в целом по двум стади м выщелачивани составл ет, %: НикельБолее 99 КобальтБолее 98 МедьДо 0,03 Железо65-70. Дл выщелачивани примен ют смесь серной и СОЛЯНОЙ КИ1СЛОТ потому, что нри выщелачивании в одной се,р«ой Кислоте врем операций увеличиваетс до 2 час на первой стадии и до 4 час на второй стадии. При этом общее извлечение никел в раствор не превышает 60%. Нредмет изобретени Способ переработки файнштейна, в частности медно-Еикелевого, выщелачиванием кислым раствором в две стадии при температуре ниже точки кипени раствора с продувкой воздухом на пе,рвой стадии и перемешиванием пульпы на обеих стади х, отличающийс тем, что, с целью повышени степени разделени меди и никел ,и извлечени никел и кобальта в раствор, в качестве выщелачивающего раствора используют сульфатнохлоридный ра створ, причем на второй стадии через пульпу пронускают посто нный, ток н потеициал нерастворимого анода поддерживают не более 0,5 в.(54) METHOD OF FACTORY PROCESSING you from 80 to 200 g / l (preferably 190 g / l) and ool. Acid - from 60 to 120 g / l (preferably 80 g / l). The total acidity of the mixture, 3.8–4.2 g-eq / l, ensures that the final solution after the first stage is obtained. The filtered solution after the second stage is directed to the first stage of the leaching of the pumping to reduce the free acidity and at the same time replenishing it with nickel due to the dissolution of fresh matte during the blowing of air O: M pulp. Sulfide residue p-after the second stage, containing,%: copper 72, liquor 0.4-0.5, cobalt 0.02-0.04, iron 2.5-3.5, sulfur 22-24, further processed according to one of the known methods, for example, by dissolving in autoclaves with subsequent reduction of copper by hydrogen or by electroplating. Both leaching stages are carried out at a temperature below the boiling point of the solution (preferably 90 ° C) and the ratio L: T (3-5): 1. The leaching time for each stage is from 1 to 1.5 hours. In both leaching stages, the solution is saturated with hydrogen sulfide, so that the noble metals are completely converted to a copper sulphide product. The current consumption for leaching operations with the imposition of a direct current is about 450 KW per ton of nickel that has passed into the solution. Extraction of metals into the solution as a whole in two stages of leaching is,%: NickelMore than 99 CobaltMore than 98MedO up to 0.03 Iron65-70. A mixture of sulfuric acid and SALT KI1SLOT is used for leaching because in the case of leaching in one sec, the acidic operation time increases to 2 hours in the first stage and to 4 hours in the second stage. In this case, the total extraction of nickel in the solution does not exceed 60%. Invention method of processing Feinstein, in particular copper-Nickel, by leaching with an acidic solution in two stages at a temperature below the boiling point of the solution with air blowing at the ne, voiding stage and mixing the pulp in both stages, in order copper and nickel, and extraction of nickel and cobalt into the solution, a sulfate-chloride solution is used as a leaching solution, and in the second stage a constant current of potential is passed through the pulp The water does not support more than 0.5 volts.
