Gold Ore Processing Project and Copper Concentration Project

Application:The Whole Project
Pump Configuration:EHM-10ST, EVM-150S
Time:2009

Project Description

Gold mine are widely distributed in China. The most proven gold reserves 

are located in the eastern and central regions, accounting for more than 

75% of the total reserves. Shandong, Henan, Shaanxi, Hebei provinces 

have reserve more than 46% of oxidized gold rock deposit.

With largest gold output, third copper output and sixth Zinc output, 

Zijin Mining Group Co., Ltd is well-known Chinese mining enterprise

 and has many projects in many regions. As its long-standing supplier,

 Excellence was entrusted with the gold mine project in Fujian Province 

and provided the slurry pump solution for the whole project.

Parameters (of one working site):
C_w(Weight concentration): 20%
Particle Size: 0.074mm

Solution

Excellence has provided four varied pumps according to customer’s demand.

Pump Model: EHM-10ST Slurry pump

Driving Method: DC
Installation: flow backward 1m
Pump Configuration：Pump with backup

After-Service

Excellence's service has been well recognized by Zijin Mining Group Co., Ltd. Our engineer

 has checked the project every quarter and communicated with pump maintenance personnel.
The pumps had worked for 3 years without any glitch. Only an expeller ring was replaced 3 years

 later, with other wet parts working normally up to now.

Copper Concentration Project

Application:The Whole Project
Pump Configuration: EHM-4X,65EZL-30,80EZL-36,50EZ-A33,EHR-4X,
Time:2012

Project Description

Copper is mainly distributed in central Africa, especially in Zambia. Zambia is

 nicknamed as “the kingdom of copper”, accounting for around 6% of world’s 

detected copper reserves. Large in reserve, the copper ores in Zambia is also 

of high grade, and it is the fourth largest copper producer and the copper mining

 has boosted local economic for a long time. Besides Zambia, Congo is also rich 

in copper resources. Copper reserve in Congo and Zambia is as high as

 22 million tons, accounting for 83% of the total copper reserve in Africa.

We are in charge of the slurry pump solution of a client's newly invested 

copper concentration project. With years of experience, our client  is in the leading 

position in mining field. The solution has successfully lived up to

 the expected daily output is 1000 tons. So far, we have provided

 35 pumps and spare parts for one year.

Parameters of some pump application site:
Q=240.73m³/h      H=36m        SG=1.54
Q=40m³/h              H=13m        SG=1.53
Q=125m³/h           H=13.5m     SG=1.18
Q=20.22m³/h        H=18m        SG=1.31
Q=117m³/h           H=14m        SG=1.28

Solution

Excellence engineers have come up with the optimal solution in light of parameters, efficiency and maintenance.

After-Service

In the consideration of coming project initiation date, we advanced our delivery date to spare enough time for client to arrange production schedule. In addition, Excellence engineer went to Africa to give installation guidance in accordance with contract.
