In Angola’s alluvial diamond fields, where infrastructure is sparse and flexibility is key, our client found success with a compact 5TPH mobile diamond plant. Designed for portability and off-grid operation, this turnkey solution combines a trommel scrubber and jig separator to deliver efficient diamond recovery—even in remote locations. Whether you’re a small-scale miner testing new deposits or optimizing an existing operation, this case study reveals how mobility, simplicity, and diesel-powered reliability can transform diamond recovery in challenging environments.
Project Case: Turnkey Mobile Diamond Processing in Angola
This 5 tph alluvial diamond processing plant is designed for a single client in Angola.
1. Customer’s Alluvial Diamond Ore Project Information
- Location: Angola
- Raw ore condition: alluvial diamond wash plant
- The customer’s main requirements are 5tph as a starting point and a separate 30tph trommel screen for another site. High-quality machines and fast goods delivery require mobile solutions.
2. Customized Solution
The solution is designed based on the client’s mining conditions and requirements.
Engineered package included: The mobile 5tph trommel screen and jig separator all-in-one diamond wash plant is configured with a hopper, one trommel screen, one jig separator, one water pump for feeding the trommel screen, one water pump for back wash pump for jig separator, one diesel generator, and one set of 30tph mobile trommel screen machine for other purposes.
3. How It Works?
- The excavator or loader feeds the hopper of the trommel screen.
- The trommel screen mesh is 20mm. The 0-20mm material will be washed and flow to the jig separator.
- The jig separator screen mesh is 1.9mm. The jigging machine uses an over-screen discharge method. Lighter minerals will be washed away by the water, while heavier minerals like diamonds will remain on the screen.
4. FAQ During Communication
Question: I am looking for a small portable diamond wash plant? Do you have any recommendations?
Answer: Sure, we have one mobile trommel screen/scrubber combined with one jig separator diamond plant, which is very popular. This equipment is simple and easy to use. The trommel screen/ore washer is responsible for washing and screening the ore, and then the screened ore enters the jig concentrator for gravity separation, directly yielding diamond concentrate.
Question: There is no power in my mine site. Can it be directly powered by diesel fuel?
Answer: Yes, no problem. However, considering that this mobile jigging plant includes a rotary screen, a jigging machine, and two water pumps, I suggest equipping it with a diesel generator set to power the entire processing line, which would be more convenient for management.
Question: Do you offer the engineering service for installation guidance?
Answer: Yes, no problem. But for this plant, the machine is simple, and the flowsheet is very simple. There is no need to send an engineer to install. If you have any engineering services, we can provide online services.

Conclusion
Angola’s 5TPH mobile diamond plant proves that small-scale mining doesn’t mean sacrificing efficiency. With its modular design, diesel-powered autonomy, and gravity-based recovery, this solution offers a low-risk entry point for artisanal miners while scaling potential for larger operations. If you’re exploring alluvial diamond mining in Africa or beyond, let this project inspire your next move—because sometimes, the biggest opportunities come in the smallest, most mobile packages.
