The feasibility of ferronickel production from a low-grade limonitic laterite ore was investigated. The ore was first calcined and then prereduced in the solid state. The reduced ore was then smelted to produce ferronickel. The effects of coal addition, smelting temperature, and retention time on the process were investigated. Chemical and physical losses in the slag were separately quantified. Coal addition was the main parameter that controlled the ferronickel grade and losses in the slag. The melting point of the slag was well below that of the ferronickel, which enhanced metal-slag separation and minimized physical losses in the slag. A microstructural study of an industrial slag revealed that Cr-rich particulates, which were suspended in the slag, were mainly responsible for the physical losses in the slag.

EVALUATION OF LOW GRADE IRON ORE DEPOSIT IN ERZINCAN-TURKEY FOR IRON ORE PELLET CONCENTRATE PRODUCTION
SİVRİKAYA, OSMAN; Arol, Ali İhsan (2012-01-01)
In this study the separation possibility of gangue minerals from a low grade magnetite ore with 45% Fe from an iron ore deposit located near Erzincan-Turkey was investigated. The iron ore deposit consists of mainly magnetite mineral. Hematite is the second iron oxide found in the deposit. The gangue minerals contain mainly SiO2 and Al2O3 impurities. The main object of the research is to investigate the production of a concentrate suitable for iron ore pellet production. The concentrate for pellet production...
Effect of iron and molybdenum addition on photofermentative hydrogen production from olive mill wastewater
Eroglu, Ela; Gündüz, Ufuk; Yucel, Meral; Eroglu, Inci (2011-05-01)
Photofermentative hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001 was assessed under iron and molybdenum supplementation. Control cultures were only grown with 2% OMW containing media. The analysis included measurements of biomass accumulation, hydrogen production, pH variations of the medium, and changes in the chemical oxygen demand (COD) of the wastewater. Growth under control and Mo-supplemented experiments yielded about the same amount of biomass (similar to 0.4 ...
Study of adsorption characteristics of long chain alkyl amine and petroleum sulfonate on silicates by electrokinetic potential, microflotation, FTIR, and AFM analyses
ÖZÜN, Savaş; Atalay, M. Umit; Demirci, Şahinde (Informa UK Limited, 2019-05-19)
The long-chain alkyl amines and petroleum sulfonates are mostly used to remove unwanted minerals from feldspar ores in acidic pHs. In this study, their adsorption characteristics on pure albite and quartz were investigated by electrokinetic potential measurements, microflotation tests, Fourier transform infrared spectroscopy, and atomic force microscopy studies. According to the results, amine had strong influence on zeta potentials of both albite and quartz turning them positive and resulting over 90% flot...
PRODUCTION OF CRUDE FERRONICKEL FROM SIVRIHISAR LATERITE ORES OF TURKEY
KESKİNKILIÇ, ENDER; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz Ali (2013-03-07)
In the current work, laboratory-scale smelting experiments were conducted using Sivrihisar laterites (1.26% Ni). The ore samples previously subjected to drying, calcination and prereduction stages were smelted in alumina crucibles in a horizontal tube furnace under argon atmosphere. For the smelting system used in the present work, 1550 degrees C and 40 minutes were determined to be the optimum smelting temperature and time, respectively. 25% excess coal addition in prereduction stage was reported to be cru...
Laboratory production of calcium sulfoaluminate cements with high industrial waste content
Canbek, Ogulcan; Shakouri, Sahra; Erdoğan, Sinan Turhan (Elsevier BV, 2020-02-01)
A drawback of conventional calcium sulfoaluminate (CSA) cement production is the use of the costly raw material bauxite as a source of alumina to form the main clinker phase ye'elimite. Replacement of bauxite with industrial wastes can benefit CSA cements economically and environmentally. This study demonstrates the use of high amounts of red mud, a sulfate-rich/high-lime fly ash, and desulfogypsum as raw materials in producing CSA clinkers and cements with better mechanical performances than an all-natural...
