purpose of screening in mineral processing

Dec 03, 2020 The purpose of the independent screening operation is to obtain the final product requested by the mineral processing plant. For example, in ferrous metals, iron-rich ores with higher iron content are often sieved into different particle sizes, and then large-sized iron ore of acceptable size enters the smelting operation, and the fine ore is
