Since the xanthate molecule selectively adsorbs or chemically fixes on the mineral surface, it has a certain orientation, that is, a polar group is oriented toward the mineral, and a non-polar group is oriented toward the water, thereby forming a hydrophobic film on the surface of the mineral.
1. The pump body
is made of PP material, which has the characteristics of corrosion resistance
and aging resistance.
2. Use a dry
liquid seal (1~10HP):To ensure that motors and bearings are protected from
chemical gas corrosion and that the service life of the motor and pump is
prolonged.
3. It is
suitable for use in jet washing equipment, exhaust scrubber, cooling cycle and
matching filter. The pump can be used without water and will not
be damaged.
4. Innovative use of PP material for the motor
is connected with the base, compared with the traditional motor bracket can
greatly reduce the acid gas corrosion, and body weight.

(1) Wide source of raw materials, easy to prepare;
(2) low price, easy to use, that is, soluble in water, odorless, non-toxic, stable in composition, not easy to deteriorate, etc.;
(3) The fishing effect is strong and has sufficient activity;
(4) It has high selectivity, and it is better to have only one mineral.
According to the molecular structure of the collector, the collector can be classified into three types: an isopolar collector, a non-polar oil collector, and an amphoteric collector.
The heteropolar collector is an isopolar substance. Common heteropolar agents such as xanthate ( R , OCSSNa ), fatty acid ( R- COOH ) amines ( R - NH 2 ), etc. The molecules of this type of collector are composed of a polar group ( -OCSSNa , -COOH , -NH 2 ) and a non-polar group ( R- ). Not all of the polar valences in the polar groups are saturated, and thus have residual affinities which determine the activity of the polar groups. When it acts on the mineral surface, it is fixed on the surface of the mineral, so it is also called a hydrophilic group. In the non-polar group, all the valences are saturated, and therefore, they have a very low chemical activity, are not wetted by water, and are not easily reacted with other compounds, and are hydrophobic to the surface of the mineral. Figure 1 shows the relationship between the yellow drug molecule ( R-OCSSNa ) and the mineral surface with a match diagram :
Heteropolar collectors are classified into ionic and nonionic collectors (eg, polysulfides) depending on whether they are dissociable into ions. The ionic collector is further classified into an anionic collector and a cation collector according to the electrical properties of the ions that are trapped.
Figure 2 Classification of collectors
Another major class of collectors is a non-polar oil collector with a chemical formula of
In addition to polar collectors and non-polar oil collectors, there are also amphiphilic collectors. The classification of collectors is shown in Figure 2 .
Collector overview
Where it can be selectively applied to the surface of the mineral so that the mineral surface hydrophobic organic substances, known as collectors. Domestic naming of collectors often ends with the word "medicine" (yellow medicine, black medicine, etc.). As much organic compound collector, commonly used in practice, such as oleic acid yellow, oil and coal. As an industrially applicable excellent collector, the following requirements should be met:
