Q1: The function of neutral flux used in the pyrometallurgy of metal extraction is to increase the __________ of the slag.A fluidity
B basicity
C acidity
D viscosity
ANS:A - fluidity Fluidity refers to the ability of a substance to flow easily and smoothly. In the context of metallurgy, particularly in processes like smelting and refining, fluidity is a critical property of molten materials such as slag. Slag is a byproduct of the metal extraction process, consisting primarily of oxides and impurities separated from the molten metal. During metal extraction, slag must be fluid enough to facilitate the separation of impurities and to allow for efficient removal from the molten metal. Fluidity in slag is influenced by various factors, including temperature, chemical composition, and the presence of fluxes. Fluxes are materials added to the slag to modify its properties, and neutral fluxes are specifically used to enhance fluidity. By adding a neutral flux to the slag, it alters the chemical composition in a way that promotes better flow characteristics. This is achieved by reducing the viscosity of the slag, which in turn increases its fluidity. A more fluid slag can move more easily and effectively, allowing it to efficiently absorb impurities and facilitate their removal from the molten metal. In summary, fluidity in the context of metallurgy refers to the ease with which molten materials like slag can flow. Enhancing fluidity through the addition of neutral fluxes improves the efficiency of metal extraction processes by facilitating the separation and removal of impurities from the molten metal. |
