Minval Processing (MVP) designs, tests and optimises mineral processing circuits — with a flagship competence in ultra fine chromite recovery.
Part of the Mineral Valuation Group — mining advisory since 2015, 100+ projects across 13+ African countries
Across the global mining industry, the ultra fine fraction — typically the sub-75 micron material — is routinely written off as “unavoidable loss”. It reports into tailings dams, compounds across decades of operation, and in chromite specifically represents a structural loss of Cr₂O₃ units that conventional gravity circuits simply cannot recover.
We don't believe it has to be that way.
Minval Processing (MVP) is the dedicated processing division of the Mineral Valuation Group. Where the Group answers “what is this asset worth?”, we answer “how do we get the most out of it?” — turning difficult ores, and the fines other plants abandon, into recovered value.
We pair technical depth with commercial discipline — and we stay independent of the equipment we recommend.
We treat ultra fine material as ore, not waste. Our flowsheets routinely capture Cr₂O₃ units that conventional spirals and shaking tables miss.
We don't resell equipment. Every recommendation is driven by metallurgy and economics — not by an OEM commission.
Mineralogy, testwork, pilot campaigns and feasibility-grade flowsheet packages — delivered to a standard your next study stage can rely on.
Backed by the Mineral Valuation Group: independent valuations, CPRs and technical due diligence sit one phone call away.
Our specialist edge — built for the sub-75µm fraction that conventional gravity circuits abandon. Ultra fine chromite is hard for three reasons:
Comparative testwork, mineralogy-led liberation interpretation (QEMSCAN / MLA), flowsheet design, and tailings storage facility re-treatment scoping & feasibility.
From a single bench-scale campaign to bankable feasibility flowsheets.
Circuit design for the fraction conventional plants give up on — our flagship competence.
Greenfield and brownfield — concept through to feasibility-grade flowsheet packages.
Programme design, laboratory oversight and statistical interpretation you can build on.
Mass-balanced surveys. Bottlenecks found, wins quantified — and recovery, throughput and cost improved.
Independent technical reviews for investors and lenders, backed by Group valuation expertise.
Decision-grade studies — scoping, pre-feasibility and bankable — with capital and operating cost estimation.
Two decades of plant work across the full mining commodity spectrum.

Four stages from first conversation to a signed-off flowsheet your EPCM can build from.
What's the ore, what's the question, and what does success look like commercially and technically?
We won't recommend a circuit we haven't proven on your ore.
Mass balances and equipment selection — independent and stress-tested.
Documented to feasibility-study standard, ready to hand to your EPCM or operating team.
MVP is led by a team that pairs deep process-engineering expertise with the commercial discipline of the Mineral Valuation Group.
A chemical process engineer with 10+ years across platinum, gold, base metals, tin and tantalum beneficiation, Gerrit sets MVP's strategy and technical direction — bringing hands-on flotation, hydrometallurgical and operational-readiness expertise to every mandate.
A CFA charterholder with 14+ years in mineral asset valuation, feasibility studies and M&A, Gert leads MVP's commercial and financial discipline — ensuring every flowsheet and recommendation is grounded in project economics. He has led the end-to-end development of a chromite operation in Zimbabwe.
A qualified mechanical and metallurgical engineer with 14+ years designing, constructing and commissioning mineral processing plants, Herman runs MVP's delivery — turning proven flowsheets into operating circuits on time and on budget.
CFA charterholder with 15+ years and an authority on DFS/PFS models, option analysis and Monte Carlo simulation — bringing financial rigour and independent model review to every processing study.
B.Eng chemical engineer with full-cycle plant design and delivery across processing and infrastructure, from concept to commissioning — specialising in the design, commissioning and optimisation of numerous fine chrome recovery plants, PGM concentrators, and integrated spiral / tailings-retreatment circuits.
Attorney with over a decade of experience in the natural resources sector — mining rights, compliance and transactional legal work underpinning every mandate.
Metallurgical engineer (BEng, cum laude) specialising in dense-medium and gravity separation, with deep test-work expertise across chrome, iron ore, lithium and antimony, and hands-on chrome-plant management.
If your fines stream is bleeding revenue — or you suspect a tailings facility is worth more than the asset register says — we'd like to look at it.
