The method provides, that as the carbonaceous reducing agent use the wastes of production of the nickel matte taken in amount of 10-30 mass from the mass of the oxidized nickel ore, and before realization of the reduction smelting in the electric furnace they preliminary produce the nickel-containing metallic liquid melt in amount of 5-25 mass , then conduct smelting of the oxidized nickel ore with production
Sep 20, 2017 Ferronickel slag FNS is a by-product of nickel production that is used as an alternative fine aggregate. This study evaluates the workability, compressive strength, splitting tensile strength, flexural strength, modulus of elasticity and chemical leaching characteristics of concrete containing FNS from garnierite ore and fly ash.
Mar 30, 2016 Purpose To support the data requirements of stakeholders, the Nickel Institute NI conducted a global life cycle impact assessment LCIA to show, with indicators, the potential environmental impacts of the production of nickel and ferronickel from mine to refinery gate. A metal industry wide agreed approach on by-products and allocation was applied. Methods
Desulphurization of Ferronickel in the converters with oxygen is the most complex part of the technological process in the Drenas foundry. Sulphur in the ferronickel melting is mostly in the form of FeS, with a melting temperature of 1195 o C, and it has tendency to dissolve indefinitely in liquid iron. Our objective is to determine the sulphur removal coefficient, as a key indicator of
aimes to prepare ferronickel from low grade laterite nickel ore from Philippines by coal-based self-reduction process, which provides guidance for rational exploiting and utilizing of the low grade laterite nickel ore. 2. Experimental Research Method 2.1. Raw Material Pretreatment and Its Physicochemical Properties
Dec 18, 2018 Ferronickel is vital importance to modern society. It is because ferronickel is main feedstock in stainless steel production. Without stainless steel, we would not be able to enjoy many of the things that we take for granted, such as stainless steel appliances in our home and workplaces and computer.
Ferronickel Foundry in Drenas, according to the comparative method. Comparison of outputs, process parameters, and production practices, are based on review the production period November 1997 ...
The ferronickel product may be further smelted to make a high quality ferronickel product. The method is particularly suited to nickel iron hydroxide precipitate that can be produced from an acidic product liquor derived from nickel containing ore bodies by a process such as pressure acid leaching, atmospheric agitation leaching andor heap ...
Nov 01, 2020 Finally, the substituted iron and nickel ions were found to reduce to ferronickel alloy under a reductive atmosphere. The ferronickel alloy with a nickel grade of 7.05 wt. and an iron grade of 71.70 wt. was produced successfully from low-grade laterite ores in which the recovery ratios of nickel and iron were 92.44 and 91.17, respectively.
Jan 14, 2015 The present study reports the properties and hydration of blended cements with ferronickel slag, produced during the pyrometallurgical treatment of laterites for the production of ferronickel. For that purpose, the slag was ground to a specific surface area of 4,000 cm2g and added in ratios 5, 10, 15, and 20 wt. The produced blended cements were tested by
Ferronickel represents an irreplaceable alloying additive for stainless steels and also plays an important role for other materials like nickel-based and other steel alloys.1, 2 For the metallurgical production of this ferroalloy, wet laterite with a low nickel content of about 1.53 is used. Such a typical oxidic nickel resource consists of 40 SiO 2, 25 MgO, 1 Al 2 O 3, 15 Fe, 5 O ...
Aug 10, 2020 Working methods. The industrial data are parameters based on the production process of ferronickel in Drenas, during the years 19871997, and the industrial production period of Fe-Ni during the years 20072017, directly from the production process of the Fe-Ni alloy 1, 3.During the industrial processes of the analyzed years, we have determined

The last step in ferronickel production is reduction smelting of bone-dry, partially reduced nickel-rich calcine at 900 degree Celsius from the calcinationreduction kilns. View Show abstract
This study is related to the production of ferronickel alloys. Especially, melting behavior of nickel ores was fo-cused on when extracting ferronickel alloys. As an extracting method,1,2 ferronickel alloys are pro-duced from siliceous nickel ores by means of a rotary kiln modifying KruppRenn process. Siliceous nickel ore is so
The present invention relates to a process for the production of ferronickel and, in particular, relates to a highly efficient method of producing ferro-Nickel or source material for the production of ferronickel with the use of low-grade oxide Nickel ore. ... include electric furnace methods and ball-ore way Krupp from the English.
