Our flotation machines often separate gold, silver, copper, zinc, lead, nickel, molybdenum, nickel and other metal minerals. They can also be used for rough and selected ferrous metals and non-metals.
The three components in mineral flotation are mineral particles, bubbles, and liquid water. Due to the existence of flotation reagents, the contact behaviors among these three phases can be manipulated, thereby producing metals and many other materials in our modern world.
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.
Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically the value …

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was …
Sulfide fluorspar mineral processing. Flotation is the most effective method when processing sulfide fluorspar minerals. The flotation process involves using chemicals to separate valuable minerals from waste materials, taking advantage of differences in their surface properties. By creating a that attaches to the desired mineral particles, they can be …
To meet the varying conditions and requirements, two basic types of flotation machines have been developed: (1) Cell-to-cell Flotation Machine. (2) Free-flow Flotation Machine. THE CELL-TO-CELL FLOTATION …
The manner in which bubbles and particles interact with each other depends on the cell operating conditions and the type of flotation machine used. Flotation machines, in general, may be categorized into four different classes: (i) mechanical or conventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; and (iv) froth ...
An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be selectively floated from …
Flotation machine is the abbreviation of floating concentrator, refers to the completion of flotation process equipment. In the flotation machine, the ore particles and the flotation agent are mixed and stirred to form a slurry, wherein some of the ore particles are selectively fixed on the bubbles, and then float up to the slurry surface, and the remaining ore …
In the mineral processing field, flotation techniques have witnessed significant trends and best practices that are shaping the industry. One prominent trend is the increasing reliance on digitalization and data analytics. …
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or …
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel …
