Froth Flotation Handbook. What is Flotation. Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float. Minerals that float have a metallic ...

The flotation machine, also known as a flotation cell or flotation separator, is a device used in mineral processing to separate valuable minerals from gangue (unwanted material) based on their differences in hydrophobicity (ability to repel water) and buoyancy. ...

A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level, the froth continues to flow and cannot be stopped.

Flotation machines can be classified into two main categories: mechanical and pneumatic. Each type has its advantages and disadvantages, depending on the specific application. 4.1 Mechanical Flotation Machines. Mechanical flotation machines, also known as conventional flotation machines, are the most common type used in industry.

machine used. Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; and (iv) froth separators. Of these, mechanical Sotation cells have dominated the min-eral industry since the early days of Sotation and

The major components of a column flotation cell are labeled. Select the component to display a description. Column cells are considered to have 2 distinct zones; the collection zone and the froth zone. Collection Zone. Because there is no mechanical agitation, column cells have no mixing zone. Instead, particles and bubbles are in …
