40 TPH Alluvial Chrome Processing in Zimbabwe

JXSC has designed a complete Flowchart and provides a full set of processing plant machines & all accessories for alluvial chrome processing in Zimbabwe. We offer a detailed layout design with base construction drawings accordingly.

1. The processing capacity required is 40TPH.
2. The raw material is alluvial chome.

• Trommel screen
• Spiral chute
• Slurry pump
• Magnetic separator

Step 1: Raw Material Feeding

The raw alluvial chrome ore is fed into the processing plant system through a feeding hopper or conveyor.

Step 2: Washing and Screening

The raw ore enters a trommel screen where washing takes place. This equipment:

• Washes the ore material to remove clay and other impurities.
• Screens out waste material and oversized particles.
• Allows properly sized material to pass through as an underscreen product.

Step 3: Slurry Pumping

The underscreen material (washed and properly sized ore) is pumped as slurry to the gravity separation circuit using slurry pumps.

Step 4: Gravity Separation
The slurry is processed through spiral chutes for gravity concentration:

• Heavy chrome minerals are separated from lighter gangue minerals.
• The spiral chute provides high-capacity processing with effective separation.
• In this setup, a single-stage spiral system is utilized due to the high-grade nature of the raw ore.

Step 5: Magnetic Separation
The concentrate from the spiral chutes is directed to wet magnetic separators:

• This customized step removes iron contaminants from the chrome concentrate.
• Improves the quality and purity of the final chrome product.

Step 6: Tailings Management
The tailings (rejected material) from the spiral separation process are pumped to a tailings pond for proper disposal and water recovery.

Step 7: Product Collection
The final chrome concentrate (after magnetic separation) is collected as the finished product, ready for further processing or market.

Notes:
For lower-grade raw ore, a two-stage spiral configuration is recommended:

• The first stage separates the initial concentrate.
• Middling materials from the first stage are pumped to the second-stage spirals.
• This configuration achieves a higher overall recovery ratio.
