उगांडा में 1500 टीपीडी कोबाल्ट-निकेल लेटराइट प्रोसेसिंग पायलट प्लांट

खनिज तैयारी और परिष्कार:

• क्रशिंग और स्क्रह्बिंग: Two-stage crushing and attrition scrubbing to break down clayey material and liberate fines.
• आकार वर्गीकरण और डीस्लिमिंग: Hydrocyclones and vibrating screens remove fine, low-grade silts and clays to upgrade the feed to the leaching circuit.

काउंटर-करेंट डिकंटेशन (CCD) और समाधान शोधकता:

• उपकरण: Multi-stage thickener series.
• फ़ंक्शन: Separates the pregnant leach solution (PLS) from residual solids (leach residue).

अवशिष्ट और अवशेष प्रबंधन:

• उपकरण: Paste thickener, filter press, lime dosing system.
• फ़ंक्शन: Neutralizes and conditions leach residue for safe, dry-stack disposal.

Adaptable to Variable Feed: The process flow and equipment are designed to handle the natural variability in Ugandan laterite ore types (limonite vs. saprolite ratio).

Data-Driven Design: The pilot plant is fully instrumented to collect comprehensive metallurgical, operational, and economic data essential for bankable feasibility studies and ESG reporting.

उच्च-दबाव वाले अम्ल लीचिंग (HPAL) – पायलट सिस्टम:

• उपकरण: Titanium-clad autoclaves, acid pre-heaters, and flash tanks.
• फ़ंक्शन: Leaches nickel and cobalt from upgraded laterite ore using sulfuric acid under high temperature and pressure.

धातु पुनर्प्राप्ति और अवसादन:

• उपकरण: Reactors, neutralization tanks, and filters.
• फ़ंक्शन: Purifies the PLS (removes iron, aluminum) and precipitates Nickel and Cobalt as a high-grade Mixed Hydroxide Precipitate (MHP) using limestone slurry and magnesia.

Modular HPAL Pilot Unit: A compact, skid-mounted HPAL system designed to generate accurate scale-up data, process kinetics, and acid consumption rates for a future full-scale commercial plant.
