Lithium has found widespread application areas; from glass and ceramics to pharmaceutics. Moreover, last decade has witnessed a significant increase in the demand for lithium batteries. The Studies made in Turkey showed that about 2000 ppm lithium occur in boron clays. Extraction of lithium from clays was the subject of many researchers, but all concluded that it was not economical when compared to extraction from minerals and brines. A major source of the cost is the raw materials used in such an extraction process. This study aims to achieve cost reduction by extracting lithium from boron clays using natural (limestone-clay) materials and waste of boric acid production as a source of gypsum. Statistical modelling of the extraction process has enabled 18% increase in the extraction yield even under these circumstances. This study demonstrates that it is possible to design more economical processes through use of appropriate statistical modelling while using low quality materials.

Quantifying hydrophobicity of pyrite after copper activation and DTPI addition under electrochemically controlled conditions Hicyilmaz, C; Altun, Naci Emre; Ekmekci, Z; Gokagac, G (Elsevier BV, 2004-07-01) In this study, the response of the surface of pyrite to copper activation under electrochemically controlled conditions was investigated in the presence and absence of sodium diisobutyl dithiophosphinate (DTPI). The mechanism of interactions between the concerned reagents and pyrite was investigated using cyclic voltarnmetry in solutions of different pH. In addition, contact angle measurements were performed to determine the wetting behavior of the pyrite surface as a function of pulp potential and pH. The ...
Impact of rapid thermal annealing on impurities removal efficiency from silicon carbide for optoelectronic applications Barbouche, M.; Zaghouani, R. Benabderrahmane; Benammar, N. E.; Khirouni, K.; Turan, Raşit; Ezzaouia, H. (Springer Science and Business Media LLC, 2019-11-27) Impurities are of crucial interest in optoelectronic devices as they affect carrier lifetimes and electrical properties. In view of that, it is important to incorporate certain processing steps to reduce impurities effect on final devices. The aim of this work is to enhance silicon carbide SiC purity for silicon passivation. Low cost method of SiC purification is presented. This method combines three main steps consisting of formation of porous silicon carbide layers by acid vapor etching followed by a phot...
Stand-Off Through-the-Wall W-Band Millimeter-Wave Imaging Using Compressive Sensing ALKUS, Umit; Sahin, Asaf Behzat; Altan, Hakan (Institute of Electrical and Electronics Engineers (IEEE), 2018-07-01) Through-the-wall radar imaging is a research area which has gathered renewed interest with the development of powerful millimeter-wave sources and detectors. Imaging techniques that require some sort of reconstruction can suffer from slow speeds and lack of complexity in the data acquisition phase of the measurements. These reconstruction methods can be greatly improved using compressive sensing (CS)-based tools that increase speed during these processes. Here, a %V-band single-pixel imaging system based on...
Extraction of cobalt and copper from Küre pyrite concentrate Çokgör, O.; Topkaya, Yavuz Ali (Elsevier BV, 1988) Three methods were investigated for the extraction of cobalt, copper and gold from Kure pyrite concentrate. These were chloridizing roasting, chloridizing volatilization and sulphating roasting processes. For chloridizing roasting, the pyrite concentrate was dead roasted first to adjust sulfur content to about 4%. Then, the pyrite cinder obtained was mixed with NaCl and pyrite concentrate, and roasted to produce soluble chlorides of copper and cobalt. For chloridizing volatilization, copper, cobalt and g...
Effect of heat treatment on grindabilities of celestite and gypsum and separation of heated mixture by differential grinding Sener, S; Bilgen, S; Ozbayoglu, G (Elsevier BV, 2004-03-01) This study was conducted to determine thermal decomposition of gypsum (CaSO4 . 2H(2)O) and celestite (SrSO4), to examine the effect of heating on grindability and the possibility of celestite-gypsum separation by differential grinding after heating. The results indicated that no significant decomposition reaction was observed in celestite up to 900 degreesC whereas the decomposition of gypsum occurred within 100-450 degreesC.
