Manganlı demir cevherinden manganın çözündürülmesinde farklı indirgeyicilerin etkisi
(TMMOB Maden Mühendisleri Odası/The Publication of the Chamber of Mining Engineer of Turkey, 2022)
Bu çalışmada, bir manganlı demir cevherinden manganez çözünmesi indirgeyici liç yöntemiyle incelenmiştir. Sülfürik asit (H2SO4) çözeltisi içerisinde cevherden seçimli olarak manganez çözünümü için indirgeyici ajan olarak ...
Characterization of Nickel in Chromite Beneficiation Tailings by Mineral Liberation Analysis and Its Recovery by H2SO4 Leaching Followed by Oxalic Acid Precipitation
(SPRINGER, 2024)
This study investigated the recovery of nickel from tailings (0.2% Ni) obtained
in a chromite beneficiation plant using H2SO4 leaching followed by oxalic acid
precipitation. The tailings were characterized using mineral ...
Testing of 17-different leaching agents for the recovery of zinc from a carbonate-type Pb-Zn ore flotation tailing
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2021)
The recovery of zinc from a flotation tailing using 17-different leaching agents, including inorganic and organic acids, alkaline solutions and chelating agents, was investigated. The effects of the lixiviant type, acid ...
