Bor Cevher Atıklarından Rubidyumun Seçinimli Yöntemlerle Kazanımı

Öz

Rubidyumun kimyasal ve optoelektronik özelliklerden dolayı biyomedikalden kuantum hesaplamalarına, kuantum ısı motorlarından havacılığa kadar yaygın alanlarda kullanımları araştırılmaktadır. Hatta konumlama uydularında kullanılacak atom saatlerinde de rubidyum atomu kullanılmaktadır. Rubidyumun mineral yatağının bulunmamasına ragmen lityum kaynaklarında birlikte bulunmaktadır. Çalışma kapsamında Eti Maden İşletmeleri Eskişehir Kırka Bor İşletme Müdürlüğü’ne ait atık havuzundan temin edilen bor cevher atığında yapılan XRF analizinde 135,9 ppm rubidyum içeriğitespit edilmiştir. Bor cevher atığından seçimli yöntem kullanarak rubidyum elde edilmeye çalışılmıştır. Bu amaçla çalışma kavurma (i), lityumu karbonat formunda ayırma (ii) ve son olarak ise rubidyumu kazanılması (iii) olarak üç aşamada tamamlanmıştır. Bor cevher atığında bulunan 135,9 ppm rubidyumun yaklaşık %1,5 oranında çözeltiye alınması mümkün olmuştur.

Recovery of Rubidium from Boron Ore Wastes by Selective Methods

Abstract

Due to rubidium's chemical and optoelectronic properties, its usage in widespread areas ranging from biomedicine to quantum calculations, from quantum heat engines to aviation, is being investigated. Even the rubidium atom is used in atomic clocks to be used in positioning satellites. Although rubidium does not have a mineral deposit, it is found together in lithium sources. Within the scope of the study, 135.9 ppm rubidium content was determined in the XRF analysis performed on boron ore waste obtained from the waste pool belonging to Eti Mining Operations Eskişehir Kırka Boron Operations Directorate. Rubidium was attempted to be obtained from boron ore waste using a selective method. For this purpose, the study was completed in three stages: roasting (i), separating lithium in carbonate form (ii), and finally recovering rubidium (iii). It was possible to take approximately 1.5% of the 135.9 ppm rubidium found in the boron ore waste into solution.
