Machinery Used in the Uranium Ore Processing Industry
The extraction and processing of uranium ore involve several stages, each requiring specialized machinery to ensure efficiency, safety, and environmental compliance. Below is an overview of the key equipment used in uranium ore processing:
1. Exploration & Mining Machinery
Before processing begins, uranium deposits must be located and extracted. Common machinery includes:
– Drilling Rigs: Used for exploratory drilling to confirm uranium deposits (e.g., rotary drills, diamond core drills).
– Excavators & Loaders: For open-pit mining (e.g., Caterpillar 793F haul trucks, Komatsu PC8000 excavators).
– Underground Mining Equipment: Including continuous miners and shuttle cars for deep deposits.
2. Crushing & Grinding Equipment
Once mined, uranium ore undergoes size reduction:
– Jaw Crushers & Cone Crushers: Primary and secondary crushing (e.g., Metso Nordberg C150 jaw crusher).
– Ball Mills & Rod Mills: Fine grinding to liberate uranium minerals (e.g., FLSmidth ball mills).
3. Leaching Systems
Uranium is dissolved from crushed ore using chemical solutions:
– Heap Leach Pads: For low-grade ores, using sprinklers or drip systems.
– Tank Leaching Reactors: For high-efficiency extraction (e.g., stainless steel or rubber-lined tanks with agitators). .jpg)
4. Solid-Liquid Separation
After leaching, the uranium-rich solution must be separated from waste solids:
– Filter Presses (e.g., Larox PF filters): Remove solids efficiently.
– Thickeners & Clarifiers: Settle fine particles (e.g., Outotec thickeners).
5. Solvent Extraction (SX) or Ion Exchange (IX)
Purification of uranium from the leach solution:
– Mixer-Settlers: For solvent extraction (SX) using organic solvents like tributyl phosphate (TBP).
– Ion Exchange Columns: If IX is used instead of SX (e.g., fixed-bed or continuous resin systems). .jpg)
6. Precipitation & Drying
Final recovery of uranium concentrate (“yellowcake”):
– Precipitation Tanks: Where ammonia or hydrogen peroxide precipitates U₃O₈.
– Rotary Dry
