A screening plant for manganese ore is a facility or machinery set up to separate and classify manganese ore into different sizes or grades, usually by means of vibrating screens. The process involves feeding the ore into the plant, where it is screened through a series of mesh screens with varying apertures. This helps in sorting the ore particles based on size, which is crucial for subsequent processing stages such as crushing, grinding, or further beneficiation. The primary objectives are to improve the ore quality and ensure consistent particle size distribution for downstream processes like smelting or the production of ferromanganese alloys.
