As mining projects get larger, so do the leaching agitation tanks. While fabricating the equipment itself is rarely the biggest headache, getting those massive tanks to site and properly installed often has the greatest impact on project timelines.
For decades, the industry standard has been to ship steel plates to site and weld them together on location. The process involves assembling, welding, grinding, and inspecting everything before the tank can finally be commissioned.
It’s a proven method, but it comes with real drawbacks:
Extensive on-site welding
Heavy reliance on highly skilled welders
Longer installation periods
High sensitivity to weather and site conditions
Increased safety risks from hot-work operations
More complex logistics, especially for remote or overseas projects
(Traditional field welded leaching agitation tank)
All of this usually means higher labor costs and longer construction schedules. Every extra day before commissioning translates directly into lost production and added expenses.
So the question is: Can we install large leaching agitation tanks more efficiently without compromising structural integrity or long-term reliability
At Xinhai, we developed a modular leaching agitation tank precisely to solve these installation challenges.Instead of building the tank from scratch on site, our leaching agitation tanks are precision-fabricated in the factory and delivered in sections. On site, the major components are simply connected using bolted joints. In essence, you’re assembling pre-engineered modules rather than constructing the entire tank in the field.

1. Easier Installation, Simpler Maintenance
Because the linching tanks are built in sections, transportation is more practical and logistics costs are often lower — especially valuable for overseas and remote mining operations. On site, assembly is significantly faster and smoother than traditional field welding.The modular approach also pays off over the long term. Individual sections are easier to maintain and replace, giving operators greater flexibility for future upgrades or expansions.
2. Less Affected by Site Conditions
In high-altitude, remote, or overseas locations, weather and site constraints can seriously disrupt welding quality and productivity. Bolted connections largely eliminate these risks. Without large-scale on-site welding, the installation process is far less vulnerable to rain, wind, or temperature swings. It also reduces welding fumes and other environmental impacts, aligning better with modern green mining practices.
3. Faster Project Delivery
The result is clear: modular bolted tanks can dramatically shorten installation time and help you commission your project sooner.
We offer two different bolted tank designs so you can choose the one that best fits your project priorities.
Option 1: Fast-Installation Design
This version uses larger prefabricated sections with fewer connection points. Benefits include:
Fewer bolts to install
Even faster assembly
Reduced sealing surfaces (lower leakage risk)
Greater structural rigidity
Better resistance to vibration from agitators
Longer overall service life
It’s ideal for large-scale operations where rapid commissioning is critical.

Option 2: Flexible Modular Design
This highly standardized approach uses smaller, interchangeable panels.
Key advantages:
Excellent transportation flexibility
Easy replacement of individual panels
Simpler future expansion
Lower maintenance costs
Better lifecycle management
This option works particularly well for remote sites, international projects, and operations that may increase capacity later.
For mining companies, the real value of equipment goes well beyond initial purchase and setup. Xinhai’s modular leaching agitation tanks deliver advantages across transportation, installation, daily operation, maintenance, and future upgrades.
