Description
ã€Process Advantages】
Adopting mixed flotation-concentrate regrinding process can reduce
the grinding cost, and be easy to manage. Application of new
non-toxic flotation reagents is efficient and environmental
protection.
ã€Application】
Mixed flotation-concentrate regrinding process is applied for
Cu-Pb-Zn sulfide ore
[ Process Advantages ]
Creative process, low operation cost
Cu-Pb mixed concentrate regrinding process saves the grinding cost
without fine grinding all the ores are, and it makes further
monomer dissociation to create favorable conditions for the
separation of copper and lead.
[Cases]
Case 1
Tibet Lead zinc Beatification Plant is one of our successful cases.
This is 3D demo Video of the dressing plant created by our
company.
Case 2
A lead-zinc dressing plant in Yunnan, , due to the mining depth
increasing, ore properties had changed and the grade of lead and
zinc concentrate decreased, so the original flotation is not
suitable. After field investigation and analysis, Xinhai determined
the process according to multi tests: mixed flotation,
preferential flotation of copper lead concentrate, regrinding and
re-floating of copper lead concentrate, and equipped with the
Xinhai equipment. Indexes comparison as follow:
After the technical reformation, this plant increased the output
value of nearly 30000 yuan/day, and the profit increasing of 26000
yuan/day. The economic benefit is remarkable.
Case 3
A copper-lead dressing plant in Xinjiang: the ore with the close
symbiosis and fine particle distribution, the process the plant
adopted leaded to the poor concentrate grade. So Xinhai was
authorized to reform the technology.
After analysis of crude properties, Xinhai decided to adopt parts
of the preferential flotation process. Firstly, selective
collectors floated copper based on the original preferential
flotation process; then mixed flotation and regrinding the mixed
concentrate, grinding fineness can reach -38 μ m78%.
Xinhai technical reformation had the advantages of simple process
and low production cost; the recovery of copper concentrate was
90.21%; lead and zinc are qualified; lead concentrate had recovery
rate of 88.3%. Xinhai obtained highly praise from clients.
By this cooperation, clients witnessed the good device performance
and good after sale service from Xinhai. In recent years, Xinhai
has more and more cooperation with large domestic enterprises,
which enhances the Xinhai service level and exercise installation
team. Xinhai also has finished more foreign EPC projects.
Other cases:
There are many cases of Xinhai Cu-Pb-Zn Dressing Process. Welcome
to visit our company!
A copper-lead-zinc dressing plant in northwest of China, Xinhai
adopted parts preferential flotation based on technology advantages
of preferential and mixed flotation and combined with the ore
characteristics. This plant obtained good beneficiation indexes:
lead concentrate grade reached 66.52%; the recovery rate was
88.5%.
A copper-lead-zinc ore dressing plant in Sweden with the daily
output of 1000t, copper content of 0.58%, lead content of 2.85% and
zinc content 4.90%; Xinhai adopted copper-lead mixed flotation.
Final copper concentrate contains copper 20.25% and lead 6.75%, and
the lead concentrate contains lead 58.73% and copper 3.40%.
A copper lead zinc ore dressing plant in Inner Mongolia, the mainly
components of the ore are copper, lead, zinc, and a certain amount
of magnetite. According to ore properties and a series of
processing tests, Xinhai finally decided copper and lead mixed
flotation separation - mixed tailings zinc flotation-flotation
tailings weak magnetic separation process, so the plant also get
more than 65% iron concentrate in addition to the grade high of
copper, lead and zinc concentrate.
