Five mine water plants, two of them ours to run
These mine water ZLD projects cover mine drainage, mine dewatering and the domestic sewage that comes with a mine site. Every plant below carries a capacity, the salt it recovers and the year it started.
Mine water ZLD projects
When JINGYU took on its first mine water project, what the scale of these flows demanded, and how the approach changed across the five plants that followed.
Written in the company's own voice: what was done, when, and what was learned. Not a technology description, which belongs on the solution pages.
What five mine water plants taught us
To be supplied — one sentence, the single most important lesson from this sector.
To be supplied — around 80 to 120 words setting up the three points below. What goes wrong when mine water is treated as a simple, low-strength stream.
To be supplied — the conclusion, around 50 words. What a client should take away from this record.

Frequently asked questions
How large can a mine water plant get?
Baijiahaizi is designed for 3,000 m3/h of mine water, treated alongside 1,700 t/d of domestic sewage. It is the largest by design capacity in our record.
Does JINGYU own any of these plants?
Yes. Hongqinghe is a build-own-operate asset, and the first mine water ZLD plant in China. Hetaoyu is a three-station outsourced operation contract.
What is recovered from mine water?
Mostly sodium chloride and sodium sulfate. The ratio depends on the ion balance of the specific mine, so the separation route is chosen per project.
Is domestic sewage treated in the same plant?
Often yes, on its own train. At Baijiahaizi it runs through pretreatment, biological treatment, MBR, nitrogen removal and disinfection.
Can I visit one of these plants?
In some cases, subject to the client's agreement. Tell us which project interests you and we will ask.
Are full case studies available?
Yes, covering feed water, process configuration, guarantees and operating results, subject to each client's confidentiality terms.
