PT Millenia Coalindo Utama (MCU)
East Kalimantan silica sand mining concession holder and mineral processing operator equipped with wet scrubbing, hydro-sizing, high-intensity magnetic separation (200 MT/Hr nominal), and a dedicated barge loading jetty (16,000 MT/Day nominal capacity).
Independent Platform Status: IndonesiaSilica.com is an independent B2B sourcing and marketing platform. We are not the corporate parent, subsidiary, or mine owner of PT Millenia Coalindo Utama.
Authorized Coordination Role: We collaborate with PT Millenia Coalindo Utama to structure technical inquiries, pre-validate buyer specifications (SiO2, Fe2O3, PSD, volume), and coordinate qualified commercial handoffs.
Technical Due Diligence Notice: Metrics below reflect figures stated in the PT MCU Company Profile v8 (April 2026). Nominal plant capacities, approved annual quotas, and reference low-iron assays (SiO2 > 99.5%, Fe2O3 ~ 0.01%) are distinct operational parameters and must be confirmed via lot-specific laboratory COA prior to purchase.
Concession, Beneficiation & Export Infrastructure
Industrial glass and foundry buyers require verifiable physical infrastructure from pit extraction through wet beneficiation to vessel loading. Below is the documented operational layout for PT Millenia Coalindo Utama in East Kalimantan.
~1,010 Ha Silica Mining Concession
Located in East Kalimantan, Indonesia, MCU operates an open-pit silica sand concession spanning approximately 1,010 hectares with a mining license stated valid until 2044.
Buyer Check: Active annual extraction and sales volumes are governed by annual regulatory work plans (RKAB).
Washing & Magnetic Separation
Raw silica undergoes multi-stage physical beneficiation designed to remove clay slimes, organic matter, oversize pebbles, and iron-bearing heavy minerals.
Buyer Check: High-intensity magnetic separation targets Fe2O3 reduction for low-iron and clear glass grades.
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.
Buyer Check: Stockpile drainage time and barge-to-mother-vessel transshipment terms are structured per contract.
MCU East Kalimantan Site & Washing Plant Visual Inspection
Actual site photographs from PT Millenia Coalindo Utama’s East Kalimantan concession, 200 MT/hour wet washing & magnetic separation circuit, closed-loop settling ponds, and washed low-iron silica stockpiles.
Integrated Wet Scrubbing, Spiral Classification & Magnetic Separation Circuit
Elevated view of MCU’s primary processing line showing the feed screen, dual spiral classifiers, magnetic separation stage, and radial stacker conveyor discharging washed low-iron silica.
Radial Stacker & Draining Cones of Washed Low-Iron Silica Sand

Multi-Stage Sedimentation & Closed-Loop Water Recirculation Ponds
Four engineered settling compartments behind the washing plant recirculate process water for wet scrubbing and desliming while preventing uncontrolled runoff.
Open-Pit Quartz Silica Deposit & Run-of-Mine (ROM) Staging Area
Staged raw alluvial and tropical quartz silica sand reserves within MCU’s ~1,010 Ha East Kalimantan concession feeding the primary hopper.
Distinguishing Stated Capacity, Approved Quotas & Lot Assays
To support rigorous industrial procurement, IndonesiaSilica separates nominal engineering capacities from regulatory quotas and batch-specific chemical test results.

Low-Iron Beneficiated Silica
Processed through MCU's wet scrubbing, desliming, and high-intensity magnetic separation circuit for solar PV cover glass, ultra-clear glass, and precision silicate applications.
Washed Glass & Industrial Silica
Hydro-classified and deslimed quartz sand with controlled clay fines and consistent particle size distribution for float glass, container glass, and sodium silicate furnaces.
Foundry, Ceramics & Bulk Grades
High-refractoriness silica tailored by mesh window and AFS Grain Fineness Number for metal casting cores, ceramic bodies, water filtration, and industrial construction chemicals.
Documented ESG & Sustainability Practices
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:
