Kenya Manganese Ore Processing Flowchart
JXSC engineers developed an optimized processing flowchart specifically tailored to the client’s ore properties:
Raw Ore Feeding: Material is loaded into the hopper and evenly distributed by the vibrating feeder to the trommel scrubber.
Clay Removal & Initial Screening: The trommel scrubber effectively washes away clay and performs primary classification into three size fractions (0-5mm, 5-25mm, and +25mm).
Multi-Stage Processing:
- 0-5mm fraction: Directed to jig separator for fine manganese concentration
- 5-25mm fraction: Processed through a dedicated jig separator for coarse manganese recovery
- +25mm fraction: Conveyed to jaw crusher for size reduction
Crushing Circuit: Jaw crusher reduces oversized material to 0-40mm, with output sent to vibrating screen for reclassification.
Closed-Circuit Operation: +25mm material from the vibrating screen returns to the jaw crusher, creating an efficient crushing loop.
Gravity Separation: Both size fractions are processed in specialized jig separators for optimal manganese recovery.
Iron Removal: Fine manganese concentrates undergo magnetic separation to remove iron impurities, enhancing final product quality.
Customer Questions & Our Answers
1. How to increase the Mn grade?
Answer: 1st step washing off clay by trommel scrubber; 2nd step removing silica sand by jig separator; 3rd step removing Fe by magnetic separator. After going through these steps, the Mn grade will be increased a lot.
How much the grade can be improved depends on the grade of your raw ore and the proportion of the main mineral components in the raw ore. For example, Mn grade in raw ore is 18%, silica sand is about 50%, Fe content is about 15%, etc. After you provide this data to me, we can calculate how much Mn grade you will get after the process.
2. How does the jig recovery Mn?
Answer: The jig machine belongs to a gravity mineral separator; it can effectively separate heavy minerals from light minerals. The specific gravity of Mn ore is much heavier than silica sand, so it can easily separate Mn ore from sand and recover the Mn concentrates.
