How much do entry level minerals processing engineer jobs pay per year?
As of Jun 7, 2026, the average yearly pay for entry level minerals processing engineer in the United States is $69,362.00, according to ZipRecruiter salary data. Most workers in this role earn between $51,500.00 and $78,500.00 per year, depending on experience, location, and employer.
What are the key skills and qualifications needed to thrive as an Entry Level Minerals Processing Engineer, and why are they important?
To thrive as an Entry Level Minerals Processing Engineer, you need a solid understanding of chemical or metallurgical engineering principles, supported by a relevant engineering degree. Familiarity with process simulation software (such as METSIM or HSC Chemistry), laboratory testing, and safety regulations is typically required. Strong analytical thinking, attention to detail, and effective teamwork skills help you excel in this collaborative and data-driven environment. These competencies ensure safe, efficient, and innovative mineral extraction and processing operations.
What are some common challenges faced by entry level minerals processing engineers during their first year on the job?
Entry level minerals processing engineers often encounter challenges such as adapting to complex plant operations, understanding site-specific processes, and learning to troubleshoot equipment issues quickly. Balancing hands-on responsibilities with technical analysis and safety protocols can also be demanding, especially in fast-paced production environments. New engineers typically work closely with senior engineers and operators, gaining valuable experience through collaboration while gradually taking on more independent tasks as their confidence and knowledge grow.
What is the difference between Entry Level Minerals Processing Engineer vs Entry Level Metallurgist?
| Aspect | Entry Level Minerals Processing Engineer | Entry Level Metallurgist |
|---|---|---|
| Required Credentials | Bachelor's in Mining, Mineral Processing, or related field | Bachelor's in Metallurgy, Materials Science, or related field |
| Work Environment | Mining sites, mineral processing plants, laboratories | Metallurgical labs, processing plants, research facilities |
| Industry Usage | Mining companies, mineral processing firms | Metallurgical companies, smelting plants |
Both roles typically require a bachelor's degree in a related field and involve working in processing plants or laboratories. While minerals processing engineers focus on the extraction and processing of minerals, metallurgists often specialize in metal refining and material properties. The roles are similar in work environment and industry usage, with differences mainly in specialization.
What does an Entry Level Minerals Processing Engineer do?
An Entry Level Minerals Processing Engineer assists in designing, operating, and optimizing processes that separate valuable minerals from ore. They typically work under the supervision of senior engineers, conducting laboratory tests, collecting and analyzing data, and supporting plant operations. Their responsibilities may also include troubleshooting equipment, ensuring safety protocols are followed, and helping to improve the efficiency of mineral recovery. This role is crucial in mining and materials industries to ensure that raw materials are processed in an effective and environmentally responsible manner.

Job description
About Mariana Minerals
Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We're reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.
The Role
We are hiring a Process Engineering Intern to work on real, high-impact problems within the Pilot Plant Operations team in San Francisco. You will contribute directly to benchtop experiments, pilot plant test runs, and the creation of key plant operational programs, working closely with engineers and domain experts.
This role is designed to provide hands-on experience building and shipping solutions, not just supporting tasks.
What You'll Do
At Mariana Minerals, you'll be part of a mission-driven team reshaping the way critical minerals are sourced and supplied globally. You'll have the autonomy to make big decisions, the tools to innovate, and a culture that values ownership, smart automation, and collaboration.
Our culture is built on three principles:
Extreme Ownership - We take full responsibility for outcomes, relentlessly driving toward solutions.
Engineer Out Requirements, then Automate - We simplify, optimize, and then automate for scale.
Share Your Legos - We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.
Join us as we build the future of responsible mineral sourcing and supply.
Mariana is an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected status.

This role is designed to provide hands-on experience building and shipping solutions, not just supporting tasks.
What You'll Do
- Drive experiments in the lab and pilot plant to de-risk scaleup of critical minerals processing steps
- Build, test, and iterate on solutions to increase product recovery, decrease equipment downtime, controls costs, and improve health & safety
- Collaborate with engineering, management, and software engineering to build programs and applications for Mariana's operations teams
- Collaborate with cross-functional team members (engineering, operations, analytical lab, etc)
- Present outcomes and learnings at the end of the internship
- Currently pursuing or recently completed degree in chemical engineering, metallurgy, materials science, or a related field
- Strong fundamentals in process design, thermodynamics, and reaction engineering
- Hands-on experience in a laboratory, pilot plant, or commercial scale plant through previous projects, coursework, and/or internships
- Ability to design experiments, troubleshoot problems, and analyze complex datasets independently
- Excellent technical writing, communication, and teamwork skills
- Comfortable working in fast-paced environments, wearing multiple hats, and managing ambiguity
