02 / BENEFICIATION PLANT 200 MT/Hr Nominal

Washing & Magnetic Separation

Raw silica undergoes multi-stage physical beneficiation designed to remove clay slimes, organic matter, oversize pebbles, and iron-bearing heavy minerals.

Plant Throughput: 200 MT / Hour (Nominal)
Stage 1: Screening & Wet Scrubbing
Stage 2: Desliming & Hydro-Sizing
Stage 3: Magnetic Separation

Buyer Check: High-intensity magnetic separation targets Fe2O3 reduction for low-iron and clear glass grades.

03 / STOCKPILE & LOGISTICS 16,000 MT/Day

Dedicated Jetty & 100k MT Stockpile

Short 5 km haulage from the processing facility to MCU's own dedicated barge jetty reduces inland trucking bottlenecks and supports consistent vessel loading rates.

Stockpile Capacity: 100,000 Metric Tons
Mine-to-Jetty Dist: ~5 Kilometers
Jetty Loading Rate: 16,000 MT / Day (Nominal)
Delivery Modes: FOB Barge / FOB MV / CIF

Buyer Check: Stockpile drainage time and barge-to-mother-vessel transshipment terms are structured per contract.

Site Verification — Closed-Loop Settling Ponds

Four-stage sedimentation and water recirculation basins integrated directly with the 200 MT/hr wet washing circuit.

International glass and solar manufacturers increasingly audit upstream raw material suppliers for environmental compliance. According to the PT Millenia Coalindo Utama company profile (April 2026), site operations incorporate the following documented measures:

1. AMDAL Environmental Impact Compliance Operations are structured under Indonesian AMDAL (Analisis Mengenai Dampak Lingkungan) regulatory environmental frameworks and periodic monitoring.
2. Closed-Loop Water Recycling in Washing Plant The 200 MT/hr wet scrubbing and desliming circuit utilizes settling ponds and water recirculation to minimize freshwater draw and prevent uncontrolled sediment discharge.
3. Progressive Post-Mining Land Rehabilitation Staged revegetation, topsoil management, and local East Kalimantan community development programs alongside active mining blocks.
