Mechanical screening often just called screening is the practice of taking granulated 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 recyclingSmelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores including silver iron copper and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind

Hey Daniel you bring up a great point it’s really difficult to create food grade and medical grade resins out of recycled content That’s why most plastics end up being “downcycled” and turned into a material that does not need to meet the same quality needs as a food or medical grade plasticCoarse waste rejection through size based separation Author links open overlay panel DJ Bowman RA Bearman The application of minimum size reduction to value bearing material whilst still generating a saleable product or a product requiring minimum further upgrading across ore sourc As such a means of illustration is required

The simplest way to record the details of a surface outcrop is by measuring and describing a vertical stratigraphic section Ideally the location of the section should be chosen to include important stratigraphic features such as formation contacts but in practice the location is commonly determined by accessibility the presence of bars or beaches allowing us to walk along a river cut or Aluminum Extrusion Process Extrusion Defined Extrusion is defined as the process of shaping material such as aluminum by forcing it to flow through a shaped opening in a die Extruded material emerges as an elongated piece with the same profile as the die opening
