Based on 20 years of experience in mineral processing industry, Xinhai has been
committed to the development and innovation of froth flotation process, aiming at
providing professional flotation cell and comprehensive service, including from previous
beneficiation test analysis, middle flotation process design and equipment selection,
and later installation and debugging. Currently, Xinhai has provided the advanced
professional Xinhai froth flotation process for many mineral processing
projects at home and abroad.
Froth flotation process is one of the most widely mineral processing method used in
the production. It uses the difference of physical and chemical properties in
mineral surface, and rely on air bubbles buoyancy in the pulp to realize mineral
separation process. On the basis of the flotation separation, Xinhai has developed a
series of flotation reagents, which not only reduce 10% reagent
consumption, but also increase 20% flotation efficiency.
Xinhai froth flotation process can be widely used in non-ferrous metal, ferrous metal
and nonmetal minerals, especially used in roughing and scavenging of large
and medium-sized flotation plant. It can process non-ferrous metals,
such as gold, silver, copper, iron, tungsten, lead, zinc, tin, molybdenum, nickel,
tantalum, niobium and manganese ore; and also process nonmetal minerals, such as
fluorite, talc, etc.

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
According to the beneficiation test and froth flotation process requirements, Iran
300tpd gold froth floatation plant needed the following
flotation cell model:
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
2) The investment fund was limited, so the project needed to be completed as soon as
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.
Xinhai production plant was producing flotation cell of this project. The flotation cell
of this project was finished in Xinhai manufacturing plant, and was prepared for
After manufactured and purchased the flotation cell, Xinhai installation and
commissioning technicians started equipment installation and commissioning.
To help Iranian workers to operate as soon as possible, Xinhai technicians showed on-site
training for plant workers, explained equipment operation notes, helped customers
quickly establish own technical team, laid foundation for later stable operation.
In Iran 300 tpd gold froth flotation project, the ore grade was 5.61 g/t, gold
concentrate grade was 78.85 g/t, flotation recovery rate was as high as 87.16%, the
final recovery rate was up to 87.16%,the customers gave high praise for these
results. From the beneficiation test, mine design, equipment manufacture, installation
and debugging to the worker training and standard reached, Xinhai provided a series of
froth flotation process service.
