Mechanical screening, often just called screening, is the practice of taking granulated or crushed ore material and separating it into multiple grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing , agriculture, pharmaceutical, food, plastics, and recycling.

A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. [1] It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. [ 2 ]
Gyratory equipment, used in mechanical screening and sieving is based on a circular motion of the machine. Unlike other methods, gyratory screen operates in a gentler manner and is more suited to handle fragile things, enabling it to produce finer products. [1] This method is applicable for both wet and dry screening.
Screening techniques are employed within the labour market during the hiring and recruitment stage of a job application process. In brief, the hiring party (agent with less information) attempts to reveal more about the characteristics of potential job candidates (agents with more information) so as to make the most optimal choice in recruiting a worker for the role.
In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Although heap leaching is a low cost-process, it normally has recovery rates of 60-70%. It is normally most profitable with low-grade ores. Higher-grade ores are usually put through more complex milling processes where higher recoveries justify the extra cost. The process chosen depends on the properties of the ore. The final product is cathode ...
