Abstract
Изобретение относитс к способам получени синтетической хризоколлы, вл ющийс продуктом окислени медных руд, и может быть использована дл извлечени меди. Свежеосажденные гидроокись меди /II/ и кремнекислоту смешивают в стехиометрических количествах в присутствии воды. Полученную пульпу подвергают перемешиванию и нагреванию. 1 ил.The invention relates to methods for producing synthetic chrysocolla, which is a product of the oxidation of copper ores, and can be used to extract copper. Freshly precipitated copper hydroxide (II) and silicic acid are mixed in stoichiometric amounts in the presence of water. The resulting pulp is subjected to mixing and heating. 1 il.
Description
Изобретение относитс к способам получени синтетической хризоколлы, аналогичной по составу и свойствам с природной, примен емой в качестве сырь дл извлечени меди.The invention relates to methods for producing synthetic chrysocolla, similar in composition and properties to natural, used as a raw material for the extraction of copper.
Целью изобретени вл етс получение синтетической хризоколлы.The aim of the invention is to obtain synthetic chrysocolla.
Пример К 50 и 40 г соответственно свеж еосажденных гидроксида меди (и) и кремневой кислоты смеши вают с водой () в сосуде емкостью 1 л, перемешивают магнитной мешалкой при 90-95°С. Отбирают пробы пульпы через каждые 50 ч. Сопоставление ИК-спектров продукта синтеза со спектром природной хризоколлы (98% основного вещества) свидетельствует, что к первому отбору реагирует до 85% исходного гидроксида меди (II); к 100 ч практически 100%. Полученный продукт отдел ют и сушат на воздухе до посто нного веса.Example K 50 and 40 g, respectively, of freshly precipitated copper hydroxide (s) and silicic acid are mixed with water () in a 1 liter vessel and stirred with a magnetic stirrer at 90-95 ° C. Samples of pulp are taken every 50 hours. Comparison of the IR spectra of the synthesis product with the spectrum of natural chrysocolla (98% of the basic substance) indicates that up to 85% of the initial copper (II) hydroxide reacts to the first selection; to 100 h almost 100%. The resulting product is separated and air dried to constant weight.
Пример 2. Исходные компоненты в количестве, соответствующем примеру 1, в форме пульпы перемешивают при 65 С Полное отсутствие гидроксида меди (ll) и совпадение ИК-спектров синтетической и природной хризоколлы наблюдаетс лишь к 240 ч. Показатель преломлени синтетической хризоколлы 1,54, природной 1,54, гидроксида меди 1,74, кремневой кислоты 1,50.Example 2. The initial components in the amount corresponding to example 1, in the form of pulp, are mixed at 65 ° C. The total absence of copper hydroxide (II) and the coincidence of the IR spectra of synthetic and natural chrysocolla is observed only by 240 h. 1.54, copper hydroxide 1.74, silicic acid 1.50.
Химический состав синтетической хризоколлы соответствует формуле СиЗЮз 1 ,75 НгО.The chemical composition of synthetic chrysocolla corresponds to the formula CIPU 1, 75 NgO.
Кристаллооптический анализ про- , дукта указьшает на его монофазность. На чертеже представлены ИК-спек- . тры исходного гидроксида меди,(крива 1), активной кремневой кислоты (крива 2), природной хризоколлы (крива 3) и продуктов синтеза при после 50 (крива 4) и 100 ч (крива 5).Crystal optic analysis of a pro duct indicates its monophasicity. The drawing shows the IR-spec. The initial copper hydroxide (curve 1), active silicic acid (curve 2), natural chrysocolla (curve 3), and synthesis products after 50 (curve 4) and 100 h (curve 5).
Сопоставление спектров исходных компонентов, продуктов синтеза и природного соединени показывает, что продукт взаимодействи после 50 ч содержит в своем составе непрореагировавшие гидроксид меди и кремiComparison of the spectra of the starting components, synthesis products and the natural compound shows that after 50 hours the interaction product contains unreacted copper hydroxide and cream i
