Senior Gravity, Magnetic & Electrostatic Mineral-Separation Specialist — GCM-1

  • Denver, CO

Senior Gravity, Magnetic & Electrostatic Mineral-Separation Specialist — GCM-1

Location: Remote — anchored to Denver, Colorado
Engagement: Contingent consulting/project-based assignment
Anticipated compensation: $150–$300 per hour or a negotiated fixed price for a defined work package
Travel: International travel may be required
Opportunity: USTDA Global Critical Minerals Project Scoping Services

Position Summary

Axyde Analytics is assembling a multidisciplinary expert cadre for a time-sensitive proposal to the U.S. Trade and Development Agency. If Axyde receives the award, USTDA may request support evaluating prospective international mining, mineral-processing, refining, infrastructure and critical-mineral supply-chain projects.

For GCM-1, Axyde is seeking a senior specialist with substantial, directly evidenced experience in physical mineral separation, specifically:

  • Gravity concentration

  • Magnetic separation

  • Electrostatic separation

This is a deliberately narrow technical requirement. The selected specialist may contribute within a broader multidisciplinary project team, but selection for GCM-1 will be based primarily on demonstrated depth in these specific separation technologies.

This is not a general mining, metallurgy, mineral-processing, engineering or project-management position. General industry breadth will not substitute for directly relevant specialist experience.

Potential Responsibilities

Depending on the assignment, the specialist may:

  • Evaluate mineralogical and metallurgical test data for suitability for gravity, magnetic or electrostatic separation.

  • Assess whether proposed physical-separation methods are technically appropriate for a particular ore, concentrate, tailings stream or secondary feedstock.

  • Review or develop beneficiation flowsheets incorporating dense-media separation, jigs, spirals, shaking tables, centrifugal concentrators, magnetic separators, electrostatic separators or related equipment.

  • Evaluate liberation requirements, particle-size distributions, feed preparation, classification and preconcentration assumptions.

  • Assess laboratory, bench, pilot, demonstration and commercial-scale test results.

  • Review recovery, grade, mass yield, selectivity, throughput and product-quality assumptions.

  • Identify process risks, test-work gaps, scale-up limitations and requirements for additional metallurgical investigation.

  • Evaluate equipment selection, operating assumptions, capital requirements and implementation considerations.

  • Contribute to project scopes, terms of reference, work plans, budgets, schedules and technical-risk registers.

  • Prepare or independently review concise, decision-grade technical findings and recommendations.

  • Participate in remote meetings, stakeholder discussions and international site visits when required.

Required Specialized Experience

Applicants must demonstrate meaningful experience in at least one—and preferably more than one—of the following:

  • Gravity concentration of critical-mineral or polymetallic ores.

  • High- or low-intensity magnetic separation.

  • Wet or dry magnetic separation.

  • Electrostatic or high-tension separation.

  • Heavy-mineral-sands beneficiation.

  • Rare-earth, tin, tungsten, tantalum, niobium, chromite, manganese, graphite or comparable critical-mineral beneficiation.

  • Recovery of valuable minerals from tailings, waste streams or unconventional feedstocks.

  • Laboratory and pilot-scale test-work design and interpretation.

  • Commercial flowsheet development, equipment selection, commissioning or operational optimization.

Applicants must distinguish their personal technical contributions from the work performed by the broader project or organization.

Résumé Evidence Required

DO NOT SUBMIT A GENERAL RÉSUMÉ.

The submitted résumé must clearly identify:

  • At least two directly relevant physical-separation projects.

  • The minerals, ores, concentrates or secondary feedstocks involved.

  • The specific gravity, magnetic or electrostatic technologies used.

  • The applicant’s personal role and technical responsibility.

  • The scale of the work: laboratory, pilot, demonstration or commercial.

  • Relevant equipment, flowsheets, operating parameters or test programs.

  • Technical reports, designs, reviews, recommendations or other deliverables personally produced.

  • Measurable outcomes such as recovery, grade, selectivity, throughput, product quality, cost reduction or process-risk mitigation, where available.

A résumé that merely lists “mineral processing,” “beneficiation” or “metallurgy” without substantiating the required separation experience will not be advanced.

Breadth is not rewarded for GCM-1 unless the required physical-separation depth is first established.

Preferred Qualifications

  • Advanced degree in mineral processing, extractive metallurgy, mining engineering, geological engineering or a closely related discipline.

  • Professional Engineer, Qualified Person, Chartered Engineer or comparable credential.

  • Experience evaluating projects in emerging markets.

  • Experience developing independent technical reviews, feasibility-study inputs or lender/investor due diligence.

  • Familiarity with sampling, mineralogy, liberation analysis, assay QA/QC and metallurgical accounting.

  • Experience preparing English-language reports for government, financial or executive decision-makers.

Eligibility and Availability

Applicants must:

  • Be a U.S. citizen or a non-U.S. citizen lawfully admitted for permanent residence in the United States.

  • Be potentially available to begin supporting an authorized assignment within approximately 20 days, subject to final scheduling.

  • Be willing and able to travel internationally when an assignment requires it.

  • Identify any country, customer, travel, employment or conflict-of-interest restrictions.

  • Be able to perform without using or disclosing proprietary information belonging to another employer or client.

  • Authorize Axyde to tailor and reformat the submitted résumé without materially changing the applicant’s qualifications.

Contingent Nature of the Opportunity

This announcement supports proposal and contingent-workforce planning. It does not guarantee employment, contract award, minimum hours or a specific assignment. Any engagement will remain subject to contract award, assignment requirements, final role alignment, eligibility, availability, mutually acceptable compensation and execution of appropriate engagement documentation.

Application Instructions

Submit a résumé specifically tailored to gravity, magnetic or electrostatic mineral separation. Include a short statement identifying:

  1. Your strongest physical-separation subspecialty.

  2. The minerals and feedstocks with which you have worked.

  3. Two directly relevant projects and your personal technical contribution.

  4. Your current location.

  5. Your U.S.-citizen or lawful-permanent-resident status.

  6. Your international-travel availability.

  7. Your anticipated hourly rate or fixed-work-package preference.

Applicants who cannot demonstrate direct depth in gravity, magnetic or electrostatic separation should not apply to GCM-1.
