Roasting of sulphide using carbothermal reduction

, 2016
The carbothermic reduction process is a direct reduction of sulfides. It allows a roasting in which higher concentrations of metals such as molybdenum are obtained by using both a reducing agent (in this case, carbon C) and a sulfur scavenger, such as CaO so as to prevent air toxic gases pollution such as SO2.

Solar silicon from directional solidification of MG silicon produced via the silicon carbide route [PDF]

A process of metallurgical grade (MG) silicon production is presented which appears particularly suitable for photovoltaic (PV) applications. The MG silicon is prepared in a 240 KVA, three electrode submerged arc furnace, starting from high grade quartz ...

THERMODYNAMICS OF CARBOTHERMAL REDUCTION PROCESS COPPER SLAG

Journal of Chemical Technology and Metallurgy
The article analyses the thermodynamic laws of processing iron-based compounds contained in copper production slag using the method of carbothermic recovery. Evaluation of the probable direction of carbothermic reactions occurring between oxidized compounds and carbon in the slag was carried out by changing the thermodynamic values of the system.

Carbothermic reduction of metal sulfides

, 2002
Diversos metales no ferrosos como el cobre, zinc, plomo, molibdeno, níquel, cobalto, antimonio, etc. se producen principalmente a partir de sulfuros metálicos. Los métodos pirometalúrgicos convencio- nales de tratamiento de concentrados de sulfuros para la producción de metales incluyen una o más etapas de oxidación de dichos sulfuros.
