Abstract
Изобретение относитс к электрохимической технологии в процессах обогащени . Позвол ет повысить степень извлечени меди за счет использовани в известном способе получени раствора дл флотации окисленных медных руд, включающем обработку водного раствора сульфида натри в катодном пространстве электролизера,обработки раствора сульфида натри после растворени в нем серы, причем серу ввод т из расчета на образование пентасульфида. 1 табл.This invention relates to electrochemical technology in enrichment processes. It allows to increase the degree of copper recovery by using in a known method of obtaining a solution for flotation of oxidized copper ores, which includes processing an aqueous solution of sodium sulfide in the cathode space of the electrolyzer, processing the solution of sodium sulfide after dissolving sulfur in it, and sulfur is introduced based on the formation of pentasulfide . 1 tab.

Изобретение относитс к электрохимической технологии в процессах Обогащени руд и может быть использо Зйно дл извлечени меди из окислен- Ных медных руд.This invention relates to electrochemical technology in ore dressing processes and can be used to extract copper from oxidized copper ores.
Цель изобретени - повышение сте- извлечени меди при флотации, . Пример, В 100 мл раствора Сульфида натри с концентрацией г/л по S раствор ют 2 г серы из 1 асчета получени полисульфида со (тепенью полисульфидности п-5. Полу- енный раствор подвергают злектролиThe purpose of the invention is to increase the copper recovery during flotation,. Example: In 100 ml of a sodium sulphide solution with a concentration of g / l in S is dissolved 2 g of sulfur from 1 calculation of the production of polysulfide with (by means of p-5 polysulfide). The semi-diluted solution is subjected to electrolysis
у в катодной камере при плотности гока 300 А/м, Полученный раствор разбавл ют водой до концентрации i г/л S после чего подают его на флотацию. Степень извлечени меди 7,2%,in the cathode chamber at a gok density of 300 A / m. The resulting solution is diluted with water to a concentration of i g / l S and then fed to flotation. Copper recovery rate of 7.2%
I В таблице приведены данные по ст извлечени меди при введении различных количеств серы,I The table shows the data on copper recovery with the introduction of various amounts of sulfur,
; Как видно из приведенных данных, Использование предлагаемого способа ; As can be seen from the data, The use of the proposed method

позвол ет повысить степень извлечени меди, причем максимальней эффект наблюдаетс при введении серы в количестве из расчета на образование пен- тасульфида,allows to increase the degree of extraction of copper, and the maximum effect is observed with the introduction of sulfur in an amount based on the formation of pentasulfide,
Таким образом, изобретение позвол ет повысить степень извлечени меди из окисленных медньпс руд при одновременном снижении расхода сульфида натри за счет использовани элементарной серы.Thus, the invention makes it possible to increase the recovery of copper from oxidized copper ores while at the same time reducing the consumption of sodium sulphide through the use of elemental sulfur.
