Research ArticleOpen accessPhrase in the titleInvestigation into the Use of Electrochemical Extraction to Draw Gold from Refractory OresBagdaulet Kenzhalyevich Kenzhaliyev, Zamzagul Duisenovna Dosymbaeva, Renata Ramilevna Iskhakova, Essen Nurgalievich SuleimenovThis paper studies the possibility of extracting gold by electrochemical leaching through the use of a sodium thiosulfate solution. In this regard, the requirements for environmentally sound technologies play a huge and vital role. Low extraction ratios and metal losses increase the cost of this process significantly and therefore it is necessary to reduce or prevent these disadvantages. Dissolution of … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,681 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleLeaching of a Nigerian Refractory Gold Ore Using Aqua RegiaOluwasanmi Samuel Teniola, Abraham A. Adeleke, Simeon Ademola Ibitoye, Moshood Deinde ShituIn this research, refractory gold ore from Imogbara deposit in Iperindo area of Osun state Nigeria were collected systematically from various segments of the deposits at different depths to obtain a set of samples that truly represent the deposits. The 50 kg sample collected was subjected to panning in a flowing river to obtain about 1 kg-upgraded sample.

Research ArticleOpen accessIn the abstractSorption Extraction of Noble and Non-Ferrous Metals from Process Leaching SolutionsBagdaulet Kenzhalyevich Kenzhaliyev, Renata Ramilevna Iskhakova, Zamzagul Duisenovna DosymbayevaIn view of the annual increase in ore processing output for low grade or refractory gold-bearing ores, as well as recoverable raw materials, stricter requirements for completeness of gold extraction and environmental safety, the interest is rising in possible alternatives to substitute the cyanide process used in gold mining practice. One of such alternatives is to convert metals into solutions … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 18 Nov 2015 · 7,050 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Case of Refractory Salmonella Spondylodiscitis in an Immunocompetent Patient Treated Via an Extracavitary Approach, Corpectomy and Placement of Expandable CageKimon Bekelis, Oren Gottfried, Zyia L. Gokaslan et al.Problem statement: Salmonella spondylodiscitis is a rare condition that is more prevalent in patients with sickle cell disease or immunosuppression. However, it can also be found in immunocompetent patients. It usually responds well to proper antibiotics. However, surgery is rarely indicated when the infection is refractory to antibiotics, the spine is destabilized or there is an epidural component that is … …American Journal of Infectious Diseases, Vol. 6, Issue 2 · 30 Jun 2010 · 7,533 accessesView PDF Cite
