چکیده مقاله :
سابقه و هدف: روش های زیستی مانند فروشویی زیستی روش های سازگار با محیط هستند که می توانند جایگزین روش های شیمیایی و فیزیکی استخراج فلزات شوند. این مطالعه با هدف استحصال کامل طلا در دو فاز میکروبی از سنگ معدن سولفیدی موته انجام شد. مواد و روش ها: برای جداسازی باکتری های اکسید کننده آهن نمونه های معدنی در محیط کشت مایع 9K کشت شد. در فاز اول فروشویی سنگ معدنی با قطر ذره ای مختلف، تهیه و به میزان 1% به محیط استاندارد افزوده شد. پس از مدت 7 روز با روش پراش اشعه ایکس از نظر وجود کانی های سولفیدی ارزیابی گردید. برای جداسازی باکتری های تولید کننده سیانید از محیط جامد تریپتیکاز سوی آگار استفاده شد. در فاز دوم ماده فروشویی شده حاصل از مرحله اول تحت اثر باکتری های سیانوژن قرار گرفت. در نهایت رسوبات و مایع باقی مانده با روش اسپکتروسکوپی ICP ارزیابی شد. یافته ها: بر اساس نتایج حاصله، باکتری جدا شده از معدن سرچشمه از قدرت بالایی در اکسیداسیون آهن برخوردار بود. به طوری که پس از 7 روز پیریت را از سنگ معدن حذف نمود. در فاز دوم باکتری جدا شده از خاک زراعی تنکابن، توانست طلا را به میزان 0.023 میلی گرم بر لیتر بازیابی نماید. بهترین میزان بازیابی طلا در اسیدیته برابر با 7 گزارش شد. نتیجه گیری: باکتری های جدا شده در این پژوهش قادر بودند طلا را در یک فرایند میکروبی دو فازی، از سنگ معدن سولفیدی جدا و با تولید سیانید، آن را به صورت محلول در محیط بازیابی کنند.
Background & Objectives: Since biological methods for metal extraction, such as bioleaching, are environmental friendly, there are high demands to be replaced with the chemical and physical methods. The aim of this study was to extract gold from Muteh sulfide ore by two microbial phases. Materials & Methods: Isolation of iron oxidizing bacteria was performed by adding mineral samples into 9k medium. At the first phase of the mineral bioleaching process, the ores were cut into different diameters, and after adding the rocks to the standard medium (1%), they were assessed after 7 days by x-ray diffraction method to study the existence of sulfide minerals. The cyanide producer bacteria were isolated by growing into TSA solid medium. In the second phase, the materials obtained from first phase were exposed to cyanogen bacteria, and the sediments were investigated by ICP. Results: Based on the results, the isolated bacteria from Sarcheshmeh mining were able to oxidize strongly ferrous and to remove pyrite from ore after 7 days. In the second phase, the isolated bacteria from Tonekabon arable soil could remove gold of (0.023 mg/l). The best range of Au recovery was produced in pH 7. Conclusion: The isolated bacteria in this study were able to separate Au in two phases of microbial process, consisting of sulfide mineralization and recovery from aqueous form by cyanide bacteria.
