  • Dehydroxylation of high-energy ball-milled diasporic bauxite 
    Volkan Murat Yilmaz; Tunç Parlak, Tuğba; Yıldız, Kenan (SPRINGER, 2018)
    In this study, diasporic bauxite was mechanically activated for different durations (15, 30, 60, 90 and 120 min) by the planetary mono mill. The speed of the main disk and ball-to-mass ratio were kept constant at 600 rev ...

  • EFFECT OF ACID CONCENTRATION ON THE EXTRACTION OF NICKEL FROM LATERITE 
    Tunç Parlak, Tuğba; Yıldız, Kenan (TANGER LTD, 2016)
    Nickel is essential metal due to usage area as stainless steel, non-ferrous alloy production, electroplating and chemical industry. Degradation of nickel sulphides leads to extraction of nickel from laterites. High cost ...
  • Effect of Sodium Sulfate Addition on the Production of Ferronickel from Lateritic Ore 
    Tunç Parlak, Tuğba; Yıldız, Kenan (POLISH ACAD SCIENCES INST PHYSICS, 2016)
    Lateritic nickel ore from Manisa - Caldag region was roasted to form ferronickel at 1200 degrees C for 1 h with additions of metallurgical coke and sodium sulfate varying by weight 5-15% and 0-20%, respectively. Formed ...
  • Effects of Sulfation Roasting and Sodium Sulfate Addition on Dissolution of Nickel and Cobalt from Laterite 
    Tunç Parlak, Tuğba; Yıldız, Kenan (POLISH ACAD SCIENCES INST PHYSICS, 2017)
    In this study, lateritic nickel ore from Manisa-Caldag, Turkey was subjected to sulfation roasting. Experimental parameters were as follows, acid concentration (10-90 wt.%), roasting temperature (200-900 degrees C) and ...
  • Formation of SrTiO3 in mechanically activated SrCO3-TiO2 system 
    Tunç Parlak, Tuğba; Fatih Apaydin; Yıldız, Kenan (SPRINGER, 2017)
    In this study, mechanical activation process was used for intimate mixing as well as producing finely ground particles, increased surface area and improved chemical reactivity of milled materials for producing SrTiO3 from ...
