Plasma technology has emerged as a very helpful tool in a variety of sectors notably metallurgy Innovators and scientists are focused on the problem of finding a more ecologically friendly way of extracting titanium and iron metal from natural ilmenite concentrate for industrial applications A direct current DC plasma torch operating at atmospheric pressure is
Ilmenite Prices Occurrence Extraction and Uses Ilmenite also known as titanium iron titanium iron ore or by its synonym menaccanite is a frequently occurring mineral from the mineral class of "oxides and hydroxides"
A hydrometallurgical process is provided for producing pigment grade TiO2 from an ilmenite ore concentrate containing by weight a relatively high magnesium content ranging up to about 10 % an iron content of at least about 15 % and a titanium dioxide content of at least about 25 % The concentrate is selectively leached with hydrochloric acid at a concentration

1 Introduction A mineral of ilmenite type is a common raw material to produce titanium dioxide and titanium metal The ilmenite concentrate from Panzhihua which is mainly composed of FeTiO 3 MgTiO 3 and Fe 3 O 4 is an important mineral resource for TiO 2 pigment production in China [1] [2] The reduction and smelting of ilmenite in an electric arc furnace
The hydrogen reduction of Kahnuj ilmenite concentrate Kerman Iran was studied under different process parameters using Response Surface Methodology RSM The effect of major influencing parameters on the reductive mass loss of pellets made from ilmenite concentrate was elucidated The independent variables examined consisted of the reduction
The ilmenite lain in ultrafine ilmenite ore cannot be treated easily In this study a superconducting magnetic separator SMS was proposed to preconcentrate the ultrafine this process the essential condition for capturing the ilmenite from the ultrafine ore key technology for obtaining an efficient preconcentration and analysis of the ilmenite
Processing titanium ore includes several stages for extracting titanium and turning it into a final product Our company has developed 2 main concepts for dressing titanium ores the main feature of which is the method of obtaining ilmenite concentrate 1 Scheme of magnetic flotation and electrostatic separation 2
Ilmenite ore is an important Ti bearing raw material for titania pigment and titanium metal production [23] beach sand ilmenite [18] pyrophyllite ore [5] boron concentrate [31] ilmenite
The high content of iron in ilmenite ore poses a great challenge particularly in the synthesis of titanium containing products due to high susceptibility of iron Fe to corrosion
HEAVY MINERAL CONCENTRATE HMC representing approximately 5% by weight of the ore mined is pumped to the Mineral Separation Plant MSP where it is stockpiled prior to further processing HMC consists of the valuable heavy minerals ilmenite rutile and zircon other heavy minerals and a small amount of light minerals the bulk of which is silica
Experimental Procedure Thermogravimetric analysis TGA experiments are carried out on Setaram Evo TG DTA 1750 thermal analyzer The reduction of samples pre oxidized ilmenite concentrate was performed in the furnace and the weight losses were measured by the thermo balance with a sensitivity of ± 10 −4 g in order to determine the extent
This method can be used in the cleaning process of primary titanium bearing ore especially for fine grained ilmenite bearing iron ore and sometimes also in the beneficiation process of titanium bearing coarse concentrate Gongyi Forui Machinery Factory is a high quality enterprise specializing in the production of beneficiation equipment
The raw material contained ilmenite concentrate and dried coke The chemical composition of the raw material is shown in Table 1 and Table 2 and the X ray diffraction XRD diagram of ilmenite concentrate is depicted in Fig 1 Fig 1 presents that Fe existed in ilmenite form in addition to a small amount of Fe 3 O 4 [17 18] The particle
Ilmenite is the primary ore of titanium a metal needed to make a variety of high performance alloys Most of the ilmenite mined worldwide is used to manufacture titanium dioxide IiO2 an important pigment whiting and polishing abrasive Examples include aircraft parts artificial joints for humans and sporting equipment such as
On the other hand the beach ilmenite and massive ilmenite ore feedstock is usually medium to high grade and contains 40 65% TiO 2 compared to the analyzed river basin ilmenite concentrate 2 4 10 11 12 15 16 26 27 46 Besides the beach placer ilmenite or crystalline ilmenite ore has fewer impurities Si Al Fe Ca Mg Cr Mn etc than
3 Lasheen 2005 The ilmenite concentrate of both types is mineralogically different According to Hussein et al 1976 and Said 1990 Abu Ghalaga is a massive ore composed of ilmenite magnetite hematite rutile goethite and anatase representing about 70% while the balance is mainly silica The Rosetta ilmenite concentrate is more
Common Questions about Gravity Separation Primary Equipment Rotary scrubbers or trommel screens tackle impurities followed by jigs or spiral chutes for rough concentration and finally shaking tables for further concentration Process Breakdown Gravity separation utilizes the different densities of minerals Heavier tin ore settles faster than lighter
The thermodynamic aspect of the pre oxidation of ilmenite was evaluated by performing a calculation of the equilibrium reaction between ilmenite concentrate and air atmosphere pO 2 = atm at
The synthesis of pure titanium dioxide TiO2 nanomaterials from naturally occurring ilmenite FeTiO3 which is present in black sands is highly desirable due to its numerous industrial and technological applications In this study nanostructured rutile nanorods were synthesized using Egyptian ilmenite concentrate through a simple mechanical/chemical
