ROSANA · STRATEGIC RAW MATERIALS
Critical minerals sourcing Creating options for supply security.
For critical and strategic raw materials, Rosana combines technical requirements with information on alternative sources, origin, counterparties, documentation, routes and end use to build a sourcing dossier that supports decisions.

CRITICAL MINERALS
CRITICAL MINERALS
Criticality stems from dependency as well as geology.
A mineral’s strategic importance is assessed alongside its industrial role, production and processing concentration, difficulty of substitution, trade restrictions and lead times. Critical mineral lists therefore vary by country and period.
Rather than treating a single list as universal, Rosana works from the customer’s production risks: it identifies the required form, which sources can be verified and which alternatives could be activated in the event of disruption.
ASSESSMENT SCOPE
Strategic material groups
The groups below illustrate Rosana’s project assessment framework. The actual scope is determined through a review of technical specifications, commercial conditions and applicable regulations.
Lithium
Carbonate, hydroxide and other commercial forms defined by project specifications.
Cobalt
Metals, chemical compounds and intermediates for the battery supply chain.
Nickel
Metal or chemical inputs according to grade, purity and end use.
Natural graphite
Flake, micronised or other products specified according to further processing requirements.
Gallium
High-purity requirements for semiconductor and advanced material applications.
Germanium
Forms for optical, fibre, infrared and semiconductor applications.
Tungsten
Technical grade distinctions across the concentrate, oxide, powder and alloy supply chain.
Tantalum
Traceable products for electronics, superalloys and speciality metallurgy.
Niobium
Ferroalloy, high-performance steel and speciality alloy applications.
Antimony
Specified grades for flame retardants, alloys and industrial chemistry.
Titanium
Application-specific sourcing across the sponge, metal, alloy or pigment supply chain.
This list is not a statement of stock availability. As critical mineral definitions and export controls may change, current classification, origin and end use are verified before a quotation is issued.
STRATEGIC DEMAND
Which sectors use critical minerals?
Energy transition
Electric motors, wind turbines, grid infrastructure, battery systems and energy storage.
Advanced manufacturing
Robotics, precision motion, industrial automation, high-performance ceramics and speciality metallurgy.
Electronics and semiconductors
Supply chains for chips, optics, fibre, displays, sensors and high-purity technical materials.
Aerospace
Lightweight alloys, superalloys, high-temperature components and precision guidance components.
Defence systems
Sourcing of advanced materials and components subject to applicable export and end-use controls.
Healthcare technologies
Imaging, detectors, lasers and specialised technical applications requiring high purity.
SUPPLY CONTINUITY
Turn reliance on one source into a choice of options.
Identify the critical input
Clearly identify the material, form, quality and consumption rate that could bring production to a halt.
Measure single-source risk
Distinguish dependencies on producers, countries, processing facilities, ports and licences.
Test a secondary source in advance
Complete sampling, quality approval and supplier qualification before a crisis.
Establish an alternative corridor
Develop scenarios for transit, customs, delivery terms and documentation requirements.
Monitor signals
Link changes in quotas, licences, sanctions, capacity and logistics to decision thresholds.
OPERATING MODEL
Visible risks, comparable options.
- 01
Define exposure
We identify the material, technical form, consumption, stock and dependence on existing sources.
- 02
Review the market and parties
We map production, processing, origin, beneficial parties and trade controls.
- 03
Build scenarios
We compare the primary source, secondary source, alternative routes and differences in time and cost.
- 04
Coordinate execution
We track sampling, contracts, inspection, documentation, logistics and acceptance.
FREQUENTLY ASKED QUESTIONS
A clear framework for critical sourcing.
What is a critical mineral?+
A critical mineral is a raw material of high economic or strategic importance that is vulnerable to supply chain disruption. Which minerals are considered critical may vary by country, period and policy framework.
Are critical minerals and rare earth elements the same?+
No. Rare earth elements are a specific family of 17 elements. Critical mineral lists may also include a broader range of raw materials such as lithium, graphite, cobalt, gallium and tungsten.
Which critical minerals does Rosana source?+
The scope that can be considered depends on product form, purity, quantity, producer, origin, end use, licensing and current trade conditions. The example groups on this website do not guarantee stock or availability.
How is an alternative supply source assessed?+
Alongside price, we compare technical compliance, manufacturer capacity, origin, beneficial parties, quality documentation, delivery routes, licensing requirements and continuity risk.
Can work begin before a supply disruption occurs?+
Yes. Preparing secondary source, alternative route and safety stock scenarios while the existing supply chain is operating reduces decision time during a crisis.
