Ferroalloys Processing Equipment - ScienceDirect

The process by which ore is converted to a ferroalloy contains a number of steps. These include mining the ore, preparing the ore by processes such as crushing, screening, washing, grinding, or milling, and sometimes applying beneficiation processes such as flotation, followed by smelting and refining. A general view of a ferroalloys smelter is shown in Figure 4.1.
