From the Stone Age to this century, mineral processing has been used in many different applications. Considerable development of mineral processing and its physicochemical basis occurred within the last hundred years [].A breaking point in the history of mineral processing is the invention of flotation.
In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

This book highlights the principles and technologies of flotation machine mainly used in mineral processing in detail. Froth flotation is one of the most important mineral processing techniques. Over 90% of the nonferrous minerals and 50% of the ferrous minerals in the world are treated using flotation: a complicated technique including ...
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
— For industrial flotation image processing, accurate bubble size measurement and feature extraction are very important to optimize the flotation process and to improve the recovery of mineral resources. This paper presents an improved algorithm to investigate mineral flotation image segmentation for mineral processing.
Dissecting the Flotation Process. Conventional flotation cells are known to be relatively inefficient in terms of promoting particle-bubble contacting. However, the historical approach is to compensate by adding a scale-up …
— Due to the limitation of freshwater sources and increasingly stringent disposal standards [13, 74, 79], the minerals industry has attempted to increase water use efficiency, reduce freshwater utilization, and minimize water discharge, or seek alternatives to fresh water [57, 59, 78, 84, 101].It is widely accepted that flotation is the most popular …
— This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit. An alkaline solution is also slightly caustic, this will help clean the surface of the mineral. This strengthens the bond between the collector and the surface of each mineral particle.
