Jun 01, 2004· Ferronickel (FeNi; 100 kt/y, Ni 20% wt) and alumina/aluminium (750 and 160 kt/y, respectively) are among the main industrial products of Greece. The production of FeNi leads to “metallurgical wastes” at LARCO in Larymna of about 2000 kt/y of ERF slag, 180 kt/y rotary kiln gas-cleaning-system dust and 120 kt/y converter slag.
Tetrataenite is a new meteoritic mineral with ideal formula FeNi, which forms by ordering of Fe and Ni atoms in taenite. Albertsen et al. (1978a), us,ing Mdssbauer spectroscopy and X-ray diffraction, identi-fled ordered FeNi in two iron meteorites. They found it has the Ll6 (or
Feni (sometimes spelled fenno or fenim or fenny) is a spirit produced in Goa, India.The two most popular types of feni are cashew feni and toddy stone feni, depending on the original ingredient; however, many other varieties are sold. The small-batch distillation of feni has a fundamental effect on its final character, which still retains some of the delicate aromatics, congeners and flavour

Granulated Blast Furnace Slag. GBFS/GBS Granulated Blast Furnace Slag/Granulated Blastfurnace Slag berbentuk butiran/pasir merupakan residu pembakaran pada tanur (furnace) dari proses pemurnian baja atau produk samping dari pabrik baja seperti PT Krakatau Steel (Persero) Tbk. dan anak perusahaannya PT Krakatau Posco.
A FeNi smelting furnace may principally be operated with the electrodes dipped into the slag or with the electrodes above the slag, (figure 2) FIG —2 ELECTRODE METAL CASE NO. 1 SLAG METAL CASE NO. 2 In CASE 1, the electrodes have a good con-tact with the slag and the resistance may be considered as pure ohmic : E = R . I (R = 0) slag arc
Jun 01, 2017· The smelter produces about 2.0 Million tonnes of granulated slag every year . The slag is a by-product of the pyro-metallurgical process of the ore in an electric arc furnace at temperatures between 1500 °C and 1600 °C . The molten slag is granulated by rapid cooling using sea-water.
An adequate quantity of granulated slag was grinded to −500 um and the resulted powder has a mean particle size (d50) of 15.05 um, measured on a MALVERN Laser Particle Size Analyzer. stone composition of steel and FeNi Slag. Table 2. The formulation of SS/FeNi slag. International Journal of Mineral Processing, 135, 1-10.
In the production of mineral wool, the melting and crystallization behaviors of slag are the key issues to determine the final quality of mineral wool. In this study, three synthetic ferronickel slags with different B 2 O 3 contents have been prepared, and the effect of B 2 O 3 on the melting ranges of the slags has been investigated by single

Steel slag processing dewomachinery. Steel slag i ntroduction:. The steel slag crushing production line is a production line for recycling and recycling of steel slag and other resources based on the characteristics of steel slag hardness and rationally equipped provides customers with technical servs and design of 30800tph
The final FeNi product containing 30% Ni is shotted with water, screened, dried and stockpiled prior to dispatch to the port on trucks where it either bagged or loaded bulk into sea containers for shipping to customers. The electric furnace slag is granulated and transferred to the slag repository by truck

For the synthesis of inorganic polymers, an adequate quantity of granulated slag was grinded to <90 μm and the resulted powder had a mean particle size (d 50) of 15.05 μm. As shown in Table 1, the FeNi slag is a siliceous material very rich in iron oxides and rich in alumina. It also contains substantial amounts of trivalent chromium, magnesium
Oct 03, 2016· The Company completed Laboratory scale test work between 2011 and 2013 which included batch smelting test, slag testing, agglomeration behaviour of the ore, Liquidus measurement of FeNi slag under conditions corresponding to electric furnace smelting, performance of the nickel laterite in rotary kiln processing and evaluation of briquetting
Keywords: granulated slag, non-ferrous metals, electric pulse destruction, flotation, ceramic building materials. Introduction. Technologies for slag recovery are being ac-tively developed in the USA, Britain and Japan. Reportedly, grinding of 90% slag to the size of
The produced granulated slag has >98% glass content and a stone size of 1 3mm and crucially is delivered in a dry state, with no contaminated water produced and limited emissions to atmosphere. Air is drawn from the granulating chamber at 600°C, either for electricity generation or for thermal preheating of fuel or raw materials.
Dry slag granulation saves on transportation costs owing to the dry product, involves no drying at the cement factory, the dry granules do not freeze in winter thanks to low water content and the granulated slag has a higher bulk density (1.3-1.4t/m3) than water-cooled granulated slag (1.0-1.1t/m3).
