The nature of minerals that are easy to float and difficult to float is generally referred to as the floatability of minerals. Is the difference buoyant flotation available mineral beneficiation to points thereof. In the modern flotation process, the application of the flotation agent is particularly important, because after the flotation agent treatment, the floatability of the mineral can be changed, so that the mineral to be floated can selectively adhere to the bubble, thereby achieving the purpose of beneficiation.

Flotation is the same as other mineral processing methods. It is necessary to prepare the materials before the sorting, that is, the ore should be graded by grinding to achieve the concentration fineness suitable for flotation.

In addition, there are several basic operations for flotation:

1. Adjustment of pulp and addition of flotation reagents

The purpose is to cause the difference in the surface properties of the mineral, that is, to change the wettability of the mineral surface, to adjust the selectivity of the mineral surface, so that some mineral particles can adhere to the gas, while others can not adhere to the air bubbles.

Second, stir up and cause a lot of bubbles

By means of the aeration stirring action of the flotation machine, the air in the slurry is dispersed to form a large number of bubbles, or the air dissolved in the slurry is formed into a micro-saturated state.

Third, the mineralization of bubbles

The ore particles selectively attach to the bubbles, which is the most basic behavior in the flotation process.

Fourth, the formation and scraping of mineralized foam layer

The mineralized bubbles rise from the lower part of the flotation tank to the mineralized surface to form a mineralized and saturated layer, and the useful minerals are enriched into the foam, which is scraped out to become a concentrate (middle mine) product. The non-target minerals remain in the flotation cell for sorting purposes. Generally, the minerals floating in the flotation operation are useful minerals. Such flotation process is called positive flotation. Conversely, if the floating mineral is gangue, it is called reverse flotation (or reverse flotation).

Flotation process is a more complicated ore processing process. The influencing factors of Guangxi Magnetic Separator Equipment Factory can be divided into non-adjustable factors (original ore and water quality of production water) and adjustable factors (flotation process, grinding fineness, Slurry concentration, pulp pH, flotation reagent system).

Pigment&Dye

Pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures.
Pigments are used for coloring paint, ink, plastic, construction, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing are dry colorants, usually ground into a fine powder. For use in paint, this powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion. A colorant can act as either a pigment or a dye depending on the vehicle involved. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt.
