· Introduction to Mineral Processing. Mineral processing is a field that contends with procedures and technologies used for separating valuable minerals from gangue or waste rock. It is a process that converts the extracted ore through mining activity into a more concentrated material, which serves as an input for the extractive metallurgy.

Flotation has now become the most widely used process for extracting many minerals from their ores. Most kinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles.

The stratification you can see in the video is a vital part of the screening process, but it’s also important to be aware of free fall separation. If you increase the gradient of the screen (to around 20 to 30 degrees), the material no longer has the chance to build up and form a bed on the screen deck from which to stratify.
