Strengthening mineral hydrophobic, floatability and adsorbability
Such as: xanthate and aerofloat
Promote or inhibit mineral buoyancy; Adjust pulp PH and ion composition
Such as: inhibitor, activator and acid-base regulator
Promote pulp form stable foam
Such as: pine oil, cresol, fatty alcohol
Compared with common flotation reagents, Xinhai special flotation reagents not only enhances the mineral surface hydrophobicity, mineral adhesive fastness and selectivity on the bubble, but also improves more 25% mineral flotation separation speed, which plays a very important role in flotation separation efficiency and flotation index.

In May 2016, Iranian client commissioned Xinhai Mine Research Institute to conduct beneficiation test after collected 50kg samples in the site. After tested the ore properties of sample ore, Xinhai lab concluded that the ore was gold-bearing quartz vein deposit, the metal mineral were pyrite, limonite and natural gold. The ore grade is 5.61g/t.
Xinhai mineral processing plan: After finished the test in July, Xinhai Mine Research Institute carried on the preliminary exploration of its processing conditions. After compared froth flotation process with cyanide leaching process, Xinhaia Mine Research Institute found that the gold recovery rate in froth flotation process was far higher than in cyanide leaching process. Therefore, after consulting with the client, Xinhai decided to adopt two-stage closed circuit crushing, one-stage grinding and single froth flotation process to get the gold concentrate. After the grinding, then one roughing, three scavenging, three concentration, the process got 87.16% recovery rate of gold concentrate.
According to the beneficiation test and froth flotation process requirements, Iran 300tpd gold froth floatation plant needed the following flotation cell model:
| Equipment Name | Type | Unit Quantity | Power (KW) | Voltage (V) |
| Flotation cell | SF-8 | 3 | 3*30 | 380 |
| Flotation cell | JJF-8 | 7 | 7*22 | 380 |
| Flotation cell | SF-4 | 3 | 3*15 | 380 |
| Flotation cell | JJF-4 | 9 | 9*11 | 380 |
| Flotation cell | SF-2.8 | 33 | 33*11 | 380 |

In August 2016, Xinhai sent professional engineers to the site to learn about the mineral resources and construction conditions. Considered its location, mineral characteristics, the project needs to solve the following problems:
1) The project was located in the Iranian plateau, which was about 2,000 meters above sea level. The weather was cold in the winter, which needed to take into consideration;
2) The investment fund was limited, so the project needed to be completed as soon as possible.
1) Adopted reasonable and compact layout. Makes full use of the high difference to complete self-flow layout in the workshop design, meanwhile, makes the industrial plants as compact and warm as possible, which is easy to produce in winter.
2) Optimized froth flotation process, improved efficiency. According to ore characteristics, Xinhai timely controlled the dosage of flotation reagents, especially the dosage of xanthate, strictly controlled concentration density, and greatly improved the gold concentrate grade. At the same time, in order to complete the project construction fast and efficient, Xinhai personnel decisively abandoned home holiday arrangement, worked hard in the first line, so completed the construction of plant workshop 15 days in advance.
