乌干达1500吨/天钴镍红土处理试验厂

矿石准备与选矿：

• 破碎与洗涤： Two-stage crushing and attrition scrubbing to break down clayey material and liberate fines.
• 尺寸分类与脱泥： Hydrocyclones and vibrating screens remove fine, low-grade silts and clays to upgrade the feed to the leaching circuit.

逆流沉降 (CCD) 和溶液净化:

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

尾矿与残留物管理：

• 设备： Paste thickener, filter press, lime dosing system.
• 功能： 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.

高压酸浸（HPAL） - 试点系统：

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

金属回收与沉淀：

• 设备： Reactors, neutralization tanks, and filters.
• 功能： 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.
