Competitive Edge
In the Indonesian landscape of metallurgy lab and service providers, Indoterra distinguishes itself with profound and applied advantages:
Neutral Position
We maintain a neutral position, not tied to specific technologies.
Patented Innovation (IP)
Personnel are innovative and expe-rienced in research, acting as IP inventors and owners.
Comprehensive Experience
We have experience in demonstration plant and production plant operations, as well as process flowsheet development for both greenfield and brownfield projects.
High-Level Technical Expertise
Supported by high-level technical expertise and applied field experiences.
Indoterra is also actively involved in frontier research, including the deep-sea nodule process and the imperative to find a process for limonite without using HPAL.
Our Deliverables
Four Pillars of Project Success
Indoterra's services are grouped into four main pillars, designed to
reduce guesswork and accelerate project definition at every stage of
the mine cycle:
Project Clarity Suite
"From deposit to decision—reduce guesswork and accelerate your path to project definition".
We provide comprehensive services including Geo-Metallurgy Program, Ore Characterization, Mineral Processing Flowsheet Design, Process Flowsheet Simulation & Mass Balance, and Greenfield Technical Due Diligence to support the success of your mining projects.
Plant Performance Plus
"See your plant through a sharper lens—adjust, align, and improve with purpose.”
We o􀌹er services such as Process Flowsheet Optimization through test-work and simulation modeling, Reconciliation & Monitoring Spreadsheets, Mass & Energy Balance Modeling, and Tailings Metallurgy & Recovery Review to enhance the e􀌺ciency and sustainability of your operations.
Indoterra Innovation Lab
"We don't just follow tech—we build it.”
We specialize in deep-sea nodules extraction, gold and nickel dynamic heap leaching, hybrid leach technologies, converting magnesium liability in nickel laterite ore into commercial products, applying resin technology for solution concentration, transforming spent nickel laterite ore into fertile plantation media, and conducting tech validation in collaboration with reagent/equipment providers—let's partner to drive new process innovations forward.
Capability Transfer Program
"We don't just deliver—we leave your team stronger."
We o􀌹er comprehensive training and courses, ranging from testwork and experiment fundamentals to advanced process modeling, along with knowledge transfer seamlessly embedded into project delivery.
