چکیده

فروشویی میکروبی اورانیم به وسیله‌­ی باکتری اسیدی تیوباسیلوس فرواکسیدان در مقیاس آزمایشگاهی از طریق تغییر پارامترهایی چون چگالی پالپ، غلظت یون فرو به عنوان منبع انرژی، pH اولیه­‌ی محیط فروشویی، سرعت هم­زنی بررسی شد. نتایج به دست آمده نشان داد که گونه­‌ی میکروبی به کار رفته برای بازیابی اورانیم از کانسنگ عیار پایین آنومالی 5 ساغند مناسب است. %60 اورانیم در مدت 50 ساعت و چگالی پالپ (W/V) 2.5%استخراج شد. بدون فعالیت میکروبی، تنها %5 اورانیم و از طریق فروشویی شیمیایی در محیط سولفوریک اسید، تنها 8.5% اورانیم بازیابی شد.

چکیده [English]

Microbial leaching of uranium from Saghand low grade ore deposit by the acidiophilic mesophile acidithiobacillus ferrooxidants was investigated by changing the parameters such as pulp density, ferrous ions concentration as the resource of energy, initial pH of leaching solution and shaking speeds. The findings indicated that this strain is suitable for uranium recovery from the mentioned ore. About 60% of uranium could be recoverd in 50 hours by a pulp density of 2.5%(W/V). In the absence of microbial activity only about 5% of uranium was recoverd, and by the sulfuric acid leaching, only about 8.5% of uranium was extracted
