molybdenum slag processing.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

The production of ferromolybdenum at Bear Metallurgical is carried out by reducing the Molybdenum Trioxide (MoO3), contained in primary or recycled materials using FeSi (and sometimes aluminum) as a main reductant, iron or iron oxide as alloy formation agents and lime as slag conditioner in a so-called silicothermic reaction which provides the necessary heat for the process and avoids the need ...
This can be lowered to less than 0.5% by slag stripping and, in general, in the continuous process the carbon and molybdenum oxide concentrate charged to the furnace may be controlled such that the carbon content of the molten alloy in the bath and the molybdenum content of the slag, immediately prior to molybdenum stripping of the slag, and ...
Why process metal slag at all? International imports have prompted both the European and German high grade steel markets to focus on producing special quality steels with particularly high quality alloying elements. This means that valuable components – such as nickel, chromium and molybdenum – are being added to the steel.
Molybdenum is, besides nickel, copper and manganese, one of the possible alloying elements that postpone the transition point of ferrite and/or pearlite. To investigate the influence of molybdenum in thick-walled castings experiments with different molybdenum contents were performed.
The process: commonly by silico-/alumino- thermic reduction; The product: FeMo alloy with 60 and 75% Molybdenum; Byproduct: slag with very low Mo content → secondary resource Advantage of the process: high Mo recovery Challenges of the process: Relatively high cost of silicon and aluminum compared with the carbonaceous.
Metal, slag or matte are tapped periodically by means of a drilling machine and closed either with a manually placed plug or a mud gun. Metal is tapped in ladles, slag/matte is either tapped into slag pots, dry pits or granulation systems (see Fig. 4). The process gas created from the chemical reactions is
treated by using roasting-leaching process in order to recover the molybdenum content in the slag. Oxidative roasting is used to convert the iron oxide into insoluble hematite, and copper and molybdenum into the soluble form in acidic solution. Since molybdenum is associated to iron oxide spinel type phase, its recovery was influenced by the ...
The present study considers various technological approaches to the processes of complex utilization of nickel slags with preliminary additional extraction of non-ferrous metals, iron, and ways of utilization of the obtained gangue. The valuable components are often produced from waste using the mineral acids or mixtures; the metals are extracted from acid solutions in a free form or in the ...
Almost all molybdenum is recovered from low-grade deposits of the mineral molybdenite, which is naturally occurring molybdenum disulfide (MoS 2), mined either from a primary deposit, or as a byproduct of copper processing.1 In 1993, one mine extracted molybdenum ore, and nine mines recovered molybdenum as a byproduct. Two plants
A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
Feb 05, 2021· This work concerns the development of a process based on the extraction of valuable metals from EAF slag.
