TECHNOLOGY SCOUTING / PHASE 2 EXAMPLE 02
Sensor Fusion Options for Pre-Concentration at a Polymetallic Mine
How a mining team could identify sensing and sorting configurations worth taking into ore-characterisation and pilot design, rather than treating every sensor vendor as a deployable solution.
All quantities, candidate statuses and delivery paths shown in this example are hypothetical.
BACKGROUND AND DECISION NEED
A hypothetical mine operator was reassessing a low-grade copper-zinc orebody with variable mineralogy, moisture and particle size. The existing flowsheet had limited selectivity before grinding. The technical brief required a route that could operate on a 12–80 mm fraction, make a measurable discrimination decision at throughput, and accommodate changing ore domains.
Decision to support
Select a small set of external sensing, sorting and integration options that could reduce waste sent to milling without losing value-bearing material.
Technical boundary
Sensor physics | ore response | particle presentation | sorter mechanics | data layer | pilot access
HOW THE SCOUTING FIELD WAS BUILT
- Translate ore domains into observable signatures: density, elemental response, spectral response, particle geometry and moisture sensitivity.
- Search for candidate architectures, not only equipment brands: sensor, illumination or excitation, ejection mechanism, software, integrator and pilot route.
- Apply an “evidence of discrimination” gate: published ore relevance, particle range, throughput signal, comparable deployment or test access.
- Build a pilot-ready dossier for shortlisted routes, separating demonstrated capability from claims that need bulk-sample confirmation.
CANDIDATE ARCHITECTURE MAP
XRT + air ejection
XRF + belt sorting
Hyperspectral + optical
Multi-sensor fusion
The visual is a research control: it keeps the search focused on interfaces that have to work together, not on standalone supplier claims.
CANDIDATE EVIDENCE AND NEXT ACTION
A pilot-routing brief: two sensor architectures to test against representative ore domains, one option to monitor, and a data-acquisition plan defining the samples and misclassification evidence required before a capital decision.
Critical proof question
Can the sensing signal separate value-bearing particles from waste across the actual ore domains, at the required size fraction and feed presentation?
WHAT THE CLIENT WOULD RECEIVE
- A final scouting protocol with evidence cut-off date, technical boundary, inclusion rules and exclusions.
- A traceable candidate field, with source links, observation dates and rationale for advance, watch or hold status.
- Detailed evidence cards for shortlisted options, separating public facts, working inferences, source-dependent claims and unanswered questions.
- A prioritised action queue for technical diligence, laboratory or pilot work, patent review, regulatory input or potential outreach.
- An editable research workbook and a decision briefing for the client’s R&D and innovation team.
INDICATIVE DELIVERY AND WEBSITE PRESENTATION
This focused desk-research engagement could be delivered in 6–7 weeks. It excludes bulk-sample testing, vendor trials, site visits and commercial negotiations. The website version could show the decision question, one compact visual, three shortlisted candidate types and the next-proof question rather than reproducing the full evidence log.
Note: Technology Scouting identifies externally visible leads and relevant evidence. It does not prove performance in the client’s application, confirm availability or willingness to partner, establish freedom to operate, or replace qualified technical, regulatory or commercial due diligence.
Indicative source base: IEA mining innovation analysis; public OEM application notes; academic ore-sorting studies; mining conference papers.
