The Stages Involved in the Flotation Machine Process

Le 23 mars 2018, 02:57 dans Humeurs 0

The Flotation Machine method is the same as other mineral processing methods, and it is necessary to prepare the materials before sorting, that is, the ore needs to be broken, milled, and graded to reach the concentration and fineness of suitable flotation. The flotation machine operation itself has the following basic stages:

Preparation of pulp, including adjustment of slurry concentration, addition of flotation chemicals, adjustment of slurry pH, elimination of harmful ion in the flotation machine process, change of surface properties of minerals, etc. The purpose is to cause differences in the surface properties of minerals, to change the wettability of the mineral surface, to adjust the selectivity of the mineral surface, to create favorable conditions for flotation machine, so that some mineral particles can adhere to air bubbles, and some mineral particles cannot adhere to bubble.

With the aid of the aeration stirring effect of the flotation machine, air is introduced into the flotation tank, resulting in the dispersion of air in the slurry to form a large number of bubbles, or to promote the formation of microbubbles in the air dissolved in the slurry. Along with this, the ore particles are selectively attached to the bubbles, which is the most basic behavior in the flotation process.

Formation of mineralized foam layer and scraping. The mineralized foam rises from the lower part of the flotation tank to the upper mineral slurry surface of the flotation machine to form a mineralized foam layer. The target mineral concentrates in the foam, scrapes it out to form the concentrate (medium ore) product, and the non-purpose mineral remains in the Flotation tank. In order to achieve the purpose of sorting.

In general, minerals floated by flotation operations are useful minerals. Such a flotation process is called positive flotation. Conversely, flotation minerals are gangues, which are called reverse flotation (counter flotation).

Flotation Equipment use and maintenance

Flotation Equipment use and maintenance:
1, flotation machine working ability and working period, like other machines is decided to maintain and maintain the normal operation of all major components, all parts of 3-4 months to conduct a careful examination, and in the new flotation machine The first few months of work to be checked frequently;
2, only skilled personnel can be checked.
3, in order to promptly replace the vulnerable parts, to reduce downtime, we must always reserve a full set of wearing parts in the warehouse. According to the specific circumstances to determine the wearing parts of the date of use and reserves.
4, must ensure that the flotation machine operator certain technical guidance or training, and strive to fully familiar with his machine.
5, in order to avoid dirt and useless things mixed with oil, oil should be filtered, when the flotation machine
Tank Agitator work, the oil cap should be sealed.
6, after inspection, and contact with the process up and down before starting.
7, the driving sequence is: press the gate switch, press the start button.
8, driving, it is strictly prohibited to touch the rotating part of the hand.

Flotation Cell has much progress

Flotation Cell is the most important single mineral concentrating operation. It is also the most efficient, most complicated, most sensitive, most challenging and least understood mineral processing operation today. The art of flotation has been correctly called the most impressive wide-scale technical application of classical surface chemistry. Only in the last three decades has much progress been made in understanding its mechanisms.
