Meet Yelsi Patriona, Senior Scientific & Business Development Manager
As mining operations face increasing ore complexity, tighter operating margins, and growing water and sustainability constraints, the role of chemistry and flotation in unlocking value has never been more critical. Strengthening Molycop’s capability in this space is Yelsi Patriona, who recently joined Molycop as Senior Scientific & Business Development Manager, based in Cilegon.Yelsi’s appointment reflects Molycop’s continued investment in science-led, integrated solutions—expanding our capabilities in chemicals and flotation while strengthening how we support customers across Indonesia and the broader region.
A role focused on impact, not just products
Yelsi’s role sits at the intersection of science, strategy, and customer partnership. Her responsibility is not simply to develop or promote individual chemical products, but to help shape how Molycop delivers integrated chemical and flotation solutions that solve real operating challenges.This includes identifying high-value growth opportunities, working closely with customers to understand where ore complexity, water chemistry, or process variability are limiting performance, and translating those challenges into structured testwork, trials, and scalable solutions. A key part of her role is ensuring that technical validation and commercial alignment progress together—so proven improvements convert into sustainable outcomes for customers.
Why Molycop? Applying systems thinking at scale
Yelsi’s professional background spans both academia and industry, with deep experience in mineral processing, flotation science, reagent chemistry, and process optimisation under increasingly complex conditions. Throughout her career, she has been driven by systems thinking—understanding how mineralogy, chemistry, and operating strategy interact to define plant performance.What drew her to Molycop was the opportunity to apply that systems-based approach at scale.
Molycop is uniquely positioned to integrate chemistry, comminution, and process intelligence. That creates a real opportunity to help customers move beyond isolated solutions and toward more consistent, measurable performance improvements.
For Yelsi, joining Molycop represents a chance to contribute not only technical expertise, but to help shape how value is created through science-led, integrated approaches across the industry.
Supporting customers through stronger local capability
Based in Cilegon, Yelsi plays a key role in strengthening Molycop’s support for customers across Indonesia. Her focus is on building close technical partnerships—working alongside operations to understand circuit behaviour, design targeted test programs, and implement solutions that address site-specific challenges.A critical enabler of this work is Molycop’s newly established laboratory capability in the region. The lab will support structured testwork, reagent evaluation, and data-driven optimisation—allowing customers to move more quickly from concept to validated performance improvement.
By combining on-the-ground expertise with laboratory and global R&D support, Yelsi will help ensure customers benefit from faster feedback, stronger technical confidence, and solutions tailored to their operating realities.
Expanding Molycop’s capabilities in chemicals and flotation
A core part of Yelsi’s mandate is to support the expansion of Molycop’s chemical and flotation capabilities—moving beyond one-off applications toward scalable, repeatable solutions that can be deployed across similar circuits and regions.This includes helping to prioritise investment, guiding technology development based on real customer needs, and working across R&D, operations, and commercial teams to ensure solutions are practical, robust, and commercially aligned.
As customer expectations continue to shift—from individual products to long-term performance partnerships—this approach positions Molycop to deliver deeper value, stronger relationships, and sustained growth in the chemical space.
Looking ahead
What excites Yelsi most about her role is the opportunity to help shape the next phase of value creation at Molycop.“As our industry faces lower grades, constrained resources, and higher expectations, there’s a real opportunity to rethink how science, technology, and partnership come together to drive performance,” she says.
Being part of a business that can influence outcomes at scale and work alongside customers as true partners is incredibly motivating.
With Yelsi based in Indonesia and supported by growing local laboratory and technical capability, Molycop continues to strengthen how it supports customers—today and into the future.
