chromite (60–90% by volume). Chromite is generally not naturally floatable but significant quantities report to the concentrate by entrainment. This is a serious problem for the downstream smelting process, which is generally constrained to a grade of about 3% chromite. Four of …
The test recipes were simulated by Pyrosim, a Mintek developed thermodynamic process simulation package, to obtain the required flux and reductant additions in order to produce liquid slags and metals in the specified operating temperature range. The simulations also provided the process energy required.
Hydrogen production is the family of industrial methods for generating hydrogen. Currently the dominant technology for direct production is steam reforming from hydrocarbons . Many other methods are known including electrolysis and thermolysis .

Conversion of Chromium Ore Processing Residue to Chrome Steel Introduction Chromium played an important role in the industrial development of New Jersey from 1905 to 1971. During that period, chromate (Cr6+) was produced from chromite ore at three facilities in Hudson County, NJ. During the chromate extraction process, varying amounts of lime ...
In the process of smelting, a large amount of electricity is consumed. Production process for the Fe-Cr is highly electric energy intensive since all the heat needed for the endothermic reduction reactions and to achieve thermodynamic equilibrium in the furnace is supplied through electrical energy only.
The hot gases required for preheating were generated in a combustion chamber and directed to the cyclones via a calcining duct (C3 to C6). To achieve constant temperatures in the calcining section natural gas was injected. The thermal process of the POLCAL plant [3] was monitored with the aid of thermocouples and
With the successful development of ultra fine grinding technologies, a compromise has to be found between fine grinding to achieve platinum group minerals liberation and to avoid the overgrinding of gangue minerals, especially chromite gangue which is detrimental in smelting process.
This invention particularly relates to a process for the preparation of an improved copper chromite catalyst with specific composition and physical properties containing copper, chromium, zinc and aluminium as catalyst components in order to achieve selective production of tetrahydrofuran via single step hydrogenation of diethyl maleate.
