Zinc ores are recovered by many mining techniques, ranging from open-pit mining ... by flotation separation. In this process, the ore initially is crushed to about 1.9 centimetres (0.75 inch), combined with water, and ground to less than 0.1 millimetre in a ball mill. The finely ground particles and water form a slurry that flows from the mill ...

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
