High pressure acid leaching of a refractory lateritic nickel ore
MUTLU KAYA, SEVCAN; Topkaya, Yavuz Ali (2011-09-01)
This paper describes the experimental findings of the extraction of nickel and cobalt by high pressure acid leaching (HPAL) of a refractory limonitic nickel laterite ore from the Gordes region of Manisa in Turkey. By optimizing the basic HPAL process parameters: leaching at 255 degrees C with 0.30 sulfuric acid to ore weight ratio with a particle size of 100%-850 mu for 1 h of leaching, it was found that 87.3% of nickel and 88.8% of cobalt present in the ore could be extracted into the pregnant leach soluti...

The aim of this thesis study was to investigate and find the most cost effective way of extracting nickel and cobalt into the pregnant leach solution (PLS) from Gördes lateritic nickel and cobalt ore by means of sulphuric acid leaching under high temperature and high pressure conditions.The high pressure acid leach (HPAL) experiments were conducted with nontronitic and limonitic types of Gördes lateritic nickel ore, respectively. Leaching experiments of nontronite ore have shown that almost all of the nicke...
High temperature corrosion of steels used in petroleum refinery heaters
Sultan, Abdelrahman; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2005)
The oxidation of three different steels used in the construction of petroleum refineryheaters was investigated by using thermogravimetric analysis technique (TGA). C-5,P-11, and P-22 steel samples were tested in two different oxidizing environments; air and CO2+N2+H2O (that simulates the combustion products of natural gas) at two different temperatures; 450oC and 500oC. In air oxidation P-22 had the best oxidation resistance among the three steels at two temperatures. In CO2+N2+H2O environment,C-5 possessed...
