Simply, the process of screening ore material is such that the material is passed through a screen or sometimes multiple screens to classify the particles according to their respective sizes and shapes. Another use for screening is to determine the percentage of fines present in the ore and, as common practice, in the oversize.

After ore has been received, the process begins by crushing, washing and screening the ore. There may be various steps of milling, concentration or amalgamation (floatation) to separate the galena from the sphalerite and other minerals. The roasting or sintering process takes place in rotary kilns or other types of furnaces. In this way the material is sintered or converted into .

In mineral processing practices, two methods dominating size control processes are: screening and classifiion. As shown in the following figure, while screening uses a geometrical pattern for size control, classifiion uses behavior of particle's (finer than 1 mm) motion in air or liquids (water) for size control.
