First, the positive flotation process

Flotation process is suitable for sorting a siliceous phosphate ore, using Na 2 SiO 3 and other silicate minerals while suppressing anionic collector with phosphate minerals being upright flotation process, better separation, such as Ningxia Helan Mountain Mine, the process flow is shown in Figure 1. Sedimentary metamorphic silicon-calcium phosphate is an easy-to-float apatite type phosphate rock. It uses Na 2 CO 3 and Na 2 SiO 3 to suppress silicon and calcium minerals. The anion collector is directly flotation of apatite. flotation process, the ore on P 2 O 5 containing 8.0 percent, by this process can be obtained phosphate concentrate grade of P 2 O 5 more than 35%, 83% recovery of phosphorous good indicator, such as Hubei Dawu Huangmailing beneficiation plant.

Second, positive and negative flotation process

Positive and negative flotation process for sorting calcium phosphate deposition, add Na 2 CO 3, Na 2 SiO 3 and other inhibiting silicate, anionic collector flotation of phosphate and calcium magnesium carbonate minerals, Then adjust the pH to 5.5-6.0 with H 2 SO 4 or H 3 PO 4 to inhibit the phosphate, and the anion collector reverse flotation of the carbonate mineral, so that the P 2 O 5 content of the phosphate concentrate can be increased to 35.17%, good ore dressing index of MgO reduced to 0.78%, R 2 O31.97%, and phosphorus recovery rate of 91.98%, such as Guizhou Yanfu Phosphorus Mine, the process flow is shown in Figure 2.

Third, double reverse flotation process

The double reverse flotation process is suitable for the most difficult colloidal phosphate rock in phosphate ore. The process first uses H 2 SO 4 or H 3 PO 4 to inhibit phosphorus minerals, and anionic collector reverse flotation dolomite and other carbonates. After the mineral is removed, the slurry is de-slurried and then the silicate mineral is reversely floated with a cationic collector. The process flow is shown in Figure 3. However, further research is needed on high-efficiency cation collectors and beneficiation processes, such as Yichang Phosphate Mine and Jingjing Phosphate Mine in Hubei.

Cnc Plasma Cutting Machine


1).The beam uses light structural design, with good rigidity structure, light deadweight and small movement inertia.

2). The gantry structure, Y axis used dual-motor dual-driven system, X, Y, Z axis all use dual-straight rail that make the machine driving smoothly with high-precision.

3). Aiming at cutting three dimension LED character, trough metal panels and floor cutting, the accuracy can reach good indicators. Equipped with other advertise equipment (blister machine, engraving machine), forming the advertising word processing pipeline. Completely solve the traditional manual processing methods. Improve the efficiency of several times.

4). Cutting mouth is small, tidy, and avoid a second dressing processing.

5). It can apply to iron sheet the aluminum sheet, the galvanized sheet, hundred steel plates, metal plates and so on.

6). High cutting speed, high precision, and low cost.

7). The numerical control system disposes high, the automatic striking arc, the performance is stable.

8). Support ARTCAM software, Type3 produce standard G code way document, also can change software to read AUTOCAD software produce DXF form documents.
