Abstract Laterites and other oxidized nickel ores constitute a very important part of world-wide nickel reserves. The development of nickel oxide ore smelting has drawn heavily on iron and steel metallurgy. In ferronickel production, the nickel oxide and part of the iron oxide are reduced to metal in an electric furnace to form immiscible layers of slag and metal.

This study investigates the reactions of Na 2 SO 4 and its effects on iron and nickel reduction in the roasting of a high-iron and low-nickel laterite ore through gas composition, X-ray diffraction, and scanning electron microscope analyses. Results showed that a reduction reaction of Na 2 SO 4 to SO 2 > was performed with roasting up to 600℃.

As the reduction potentials of the current steelmaking routes are low, the transfer toward breakthrough-technologies is essential to reach these goals. Hydrogen-based steelmaking is one approach to realize CO 2-lean steelmaking. Therefore, the natural gas (NG)-based direct reduction (DR) acts as a basis for the first step of this transition.

Most gas-based direct reduction plants are part of integrated steel mini-mills, located adjacent to the electric arc furnace (EAF) steel plant. DRI can be either hot or cold charged to the EAF. Some steel companies ship DRI from their captive direct reduction plants to their remote steel mills and a small volume of DRI is sold to third parties.

The invention provides a method for producing ferronickel by processing laterite nickel ore in Sulawesi, Indonesia through an RKEF technology. The method comprises the following steps: 1, prescreening a laterite ore raw material by a 50mm grizzly screen, crushing a part not passing through the screen by a jaw crusher to below 50mm, and mixing the obtained crushed material with a product ...

Direct Reduced Iron (DRI) Production Plant NIPPON STEEL ENGINEERING CO., LTD. Basic Concept or Summary S-16 u A direct reduced iron (DRI) production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases.

Direct Nickel has developed a game changing pro cess for extracting nickel from laterite deposits. It will position Direct Nickel as one of the lowest cash cost producers in the global nickel industry in the next 5 years. The Process offers unparalleled co st efficiency, capital savi ngs and environmental benefits.

The plant, located in Drenas, was in a state of disrepair at the time of our purchase, as a result of bombing during the Kosovo conflict in year 1999 and subsequent general neglect. Our investments in the plant have now begun to pay off; last year the plant produced over 6000 tons of ferronickel and with the current plant dynamics and projects ...

Direct reduction of low grade nickel laterite ore to produce ferronickel using isothermal – temperature gradient January 2017 AIP Conference Proceedings 1805(1):040003

The sticking phenomenon between molten slag and refractory is one of the crucial problems when preparing ferronickel from laterite ore using rotary hearth furnace or rotary kiln processes. This study aims to ameliorate sticking problems by using silicon dioxide (SiO2) to adjust the melting degree of the briquette during reduction roasting. Thermodynamic analysis indicates that the …

Nickel slags can be produced through ferronickel preparation by the pyrometallurgical processing of laterite nickel ores; however, such techniques are underutilized at present, and serious environmental problems arise from the stockpiling of such nickel ores.

In this study, low grade nickel laterite ore was processed by means of isothermal-temperature gradient method to produce ferronickel nugget. The ore and coal as reductant were ground to obtain the grain size of less than 0.25 mm and 0.425 mm, respectively. Both ground laterite ore and coal were mixed, agglomerated in the form of cylindrical pellet by using press machine and then reduced …

Ferronickel smelting of lateritic ores is generally performed by using fossil fuels (coal, oil, natural gas, etc.) as a reductant in a rotary kiln. Nickel and cobalt are firstly reduced because iron has greater affinity to oxygen. The product is charged to converter for refining after discarding the slag
