Manufacture, assemble, test
Modules are built and run in Kimberley before they ever see the pit.
Plants
Wet plants, plus a final recovery plant.
Conventional run-of-mine through a wet plant. DMS concentrate and pan concentrate through a final recovery plant. Tested in Kimberley, then commissioned on your ground. Dry X-ray is the option when the site cannot carry water.
What you get
A recovery train, not a pile of steel.
Each plant is specified against the ore, the water, and the tons. The default is a wet ROM plant with final recovery on DMS and pan concentrate. Thornley, the dry X-ray plant, is a reference for water-scarce ground, not the template for every site.

Dry reference, not the brief
Thornley: 25,000 to 60,000+ tons a month.
Average grade 0.2 ct / 100 t, dry, since 2018. It shows what an X-ray plant can do where pans and dense medium struggled. It does not set the plant we quote first.
Commission on site
Performance testing against the agreed throughput and recovery envelope.
Train the crew
Formal operations and maintenance training, then knowledge transfer with our technicians.
Inspect and audit
Scheduled plant audits to hold peak efficiency after the honeymoon months.
Repair and replace
Parts and repairs from the same team that built the plant, not a ticket queue.
Respond to breakdowns
Prompt field response, then a design note so the failure does not repeat.
Dry option
How dry X-ray sorting works
This is not the plant we lead with. Where process water cannot be carried, an Eros dry plant is the materials-handling train around this step: feed, a single layer on the belt, an X-ray reading, and an air-jet split. The film is silent. English captions mark each stage.
01
Feed the line
Crushed ore arrives on a conveyor and drops through a vibrating feeder. The sorter only sees what the plant presents to it.
02
Lay a single layer
The feeder and belt spread the stones so they sit apart. Each rock can be scanned on its own instead of buried in a pile.
03
Read through the stone
X-ray transmission measures how each stone absorbs the beam. Minerals absorb differently, so the decision uses the interior of the rock, not only the surface colour. A line-scan colour camera can be paired with that image.
04
Eject with air
The controller fires an air-jet array only on the stones that match the sort. Product leaves on its own conveyor. No process water, dense medium, or reagents are added at this step.

Thornley is the published reference: High-tonnage Bourevestnik X-ray sorter configuration, online since 2018, from 25,000 to 60,000+ tons a month at 0.2 ct / 100 t. These frames are a method study of dry X-ray transmission sorting. They are not a photograph of that plant, and they are not a rated capacity. Size range and tons for your ground are fixed in the site assessment.
Plant configurator
Tell us the ground. We'll name the plant.
Four choices. A recommended package from the Eros group, then a site assessment request with the configuration attached.
01. What do you need?
02. Feed
03. Target throughput
04. Water on site
Select all four to see the recommended package. Nothing is sent until you request an assessment.
Ready to size it properly?
Share the deposit, water situation, and target tons. A recovery specialist will come back with a dated assessment, not a brochure.
