Optimize Every Stage — From Crushing to Pellet Feed Quality
Brazil is the world's largest iron ore producer and is rapidly scaling copper and nickel output for the energy transition. With the industry committing to 90% decarbonization by 2050, the pressure to produce more metal with less energy, less water, and fewer emissions has never been higher. Circuito AI delivers AI optimization that makes your existing concentrator produce more — without additional capex.
Why Brazilian Mining Needs AI-Driven Process Control
Brazil's mining sector is at an inflection point: record production targets, a decarbonization mandate, and a regulatory environment that demands operational transparency and data protection.
Iron Ore — More Volume, Lower Grades, Higher Standards
Brazil produced 336 Mt of iron ore in 2025 — a record — but the easy ore is running out. In Minas Gerais, average iron content is around 40% in itabirite rock, requiring energy-intensive wet processing before pelletizing. Pellet quality standards are tightening as the steel industry shifts to direct reduction iron (DRI) routes. Every percentage point of variability in pellet feed composition translates directly into furnace inefficiency downstream.
Copper and Nickel — The Energy Transition Metals
Brazil is not just an iron ore story. Copper output hit 382 kt in 2025 — the highest since 2018 — and nickel production surged 44% year-on-year. As these operations scale, they face the same flotation challenges as Chilean and Peruvian copper mines: variable ore feeds, grade-recovery tradeoffs, and the need to maximize recovery from every ton processed.
Post-Brumadinho Regulatory Environment
Since 2019, Brazil's mining regulations have become among the strictest in the world — particularly around tailings management, water use, and operational safety. The National Mining Agency (ANM) demands higher transparency, better process control, and reduced environmental footprint. AI optimization that reduces reagent overconsumption and stabilizes tailings composition directly supports compliance.
LGPD Data Compliance
Brazil's Lei Geral de Proteção de Dados (LGPD) imposes strict requirements on how operational data is collected, processed, and stored. Cloud-based optimization platforms that send plant data to external servers raise compliance questions. Circuito AI runs entirely on-premise — your data never leaves your site.
AI for Brazil's Unique Mining Profile
Circuito AI has proven results in the exact ore types and circuit configurations that define Brazilian mining — from iron ore grinding to copper-nickel flotation.
Iron Ore Grinding and Pelletizing Feed
Circuito AI has a direct, proven case study in iron ore grinding: +2.4% throughput while maintaining target particle size distribution for pelletizing. For Brazilian operations, this means more consistent pellet feed quality, higher throughput from existing mills, and lower energy per ton — directly addressing decarbonization targets.
Proven result: +2.4% throughput in iron ore grinding with maintained particle size targets. Grinding optimization also reduced process variability by up to 50% at a copper operation.
Copper and Nickel Flotation
As Brazil scales copper and nickel, flotation performance becomes the revenue lever. Circuito AI's flotation AI is proven across copper, nickel, copper-gold, and iron ore flotation circuits — monitoring 283 parameters per line, adjusting every 10 seconds, with a proprietary computer vision froth sensor for fully autonomous control.
Proven result: +0.9% extraction rate at a nickel-copper concentrator (Kola MMC). +0.78% Cu extraction with -35% concentrate quality variability at Tominski GOK. +0.65% extraction at a copper-gold-iron ore circuit (Bystrinski GOK).
Cross-Process Optimization for Integrated Plants
Brazil's large iron ore operations run integrated circuits — crushing, grinding, classification, concentration, and pelletizing feed preparation — where optimizing one stage in isolation can degrade another. Circuito AI connects all stages into a unified optimization strategy.
Proven result: At Bystrinski GOK, cross-process optimization has run for 3+ years across crushing, grinding, and flotation, reducing manual interventions by 96%.
LGPD-Compliant, On-Premise Architecture
Circuito AI is fully installed on-premise at your site. All data processing — collection, model training, inference, and control — runs within your network. No cloud dependency. No third-party cloud processors. Your IT team retains full visibility and control over data flows.
Proven result: Inherently LGPD-compliant: no operational data transferred to external servers, no third-party processors involved.
Relevant to Brazilian Operations
Circuito AI's results at iron ore, nickel, copper, and gold concentrators — running on the same ABB, Siemens, and Metso systems deployed across Brazil's mining operations — transfer directly to your plant.
