Classic Case
Yunnan lead-zinc ore dressing project had obtained great improvement in process index at the early stage. However, with the deepening mine exploration, the ore properties had a great change and caused the sharp decline in lead-zinc concentrate grade. The original floatation equipment cannot meet the production requirements. Therefore, the customer entrusted Xinhai to carry out equipment modification. Through repeated ore dressing experiment, Xinhai finally decided to adopt bulk flotation process, selective copper-lead concentrate, copper-lead concentrate regrinding and refloating, besides, Xinhai adopted SF type, JJF type flotation cell instead of original flotation cell. Finally, the main technical indicators were as follows:
|
Process |
Processing Capacity(t/d) |
Copper Recovery Rate(%) |
Lead Concentrate Grade(%) |
Zinc Concentrate Grade(%) |
Service Life of Liner(t) |
| Before |
Selective Flotation |
500 |
78.53 |
35.68 |
83.49 |
50 |
| After |
Bulk Flotation |
680 |
83.45 |
50.13 |
84.68 |
90 |
Through this upgrading, this output value was increased nearly 30000 Yuan every day, the profit was increased 26000 yuan every day. Suppose the production days are 300 days per year, this project can increase the profit: 26000 yuan * 300 days per year = 7.8 million.
Keep Improving, Pursue Excellence
As the complete mineral processing equipment manufacturers, Xinhai relies on high-quality complete sets of ore processing equipment, strong self-innovation ability and thoughtful customer service, then establishes a good brand image at home and abroad. As the hard core of the mining industry, Xinhai will lead the industry to realize leap-forward development and show the power of "Made in China".
