The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.
Low bitumen recovery and poor froth quality are always encountered when processing poor oil sands using water-based extraction processes. Application of microbial treatment of the ore prior to bitumen extraction was proposed to resolve the challenges and develop a more versatile and effective extraction process. Microbial …
Froth flotation is one of the most popular metalworking techniques, used in mineral processing, wastewater treatment, and more. This technology was first used in mineral processing in the early 20th century. A process called ore genesis yields metal ores. Extraction and refining of essential metals from ores is known as extractive metallurgy.

In mineral processing, it can be considered as the development and optimization of beneciation process by bridging mineralogical proper-ties and beneciation method to obtain valuable minerals from the ore [4 ]. Since the beneciation performance of ore
The bitumen in the froth from the poor ore is trapping significantly more water and mineral matter. The bottom center image is froth from a bad ore which has been treated. The result is a froth that is almost indistinguishable from the good ore froth with corresponding high bitumen recovery and good froth quality. 805CD
