A density difference is only the start; mineral identity and liberation decide whether gravity is useful.
Initial gravity concentration assessments for tantalum-niobium, manganese, ilmenite, zircon and other minerals with useful density differences.
Manual process review
I first check whether the valuable mineral can be identified, liberated and concentrated at a practical mass pull.
First reply within one business day Before a machine model
Check whether this route fits the ore.
The mineral name is only the starting point. These conditions decide whether this page is relevant or whether another test route is needed.
- The valuable mineral or saleable product is not yet identified
- Liberation requires excessive grinding or valuable mineral reports to slimes
- Another physical or chemical process is more appropriate than gravity
Three-question route check
Tell me how the material behaves.
These answers do not produce a final plant design. They help us identify the likely process direction, the missing evidence and the first risk worth checking.

Gravity concentration is a capability, not a mineral list
Many valuable minerals are denser than their common gangue, but that does not mean the same plant can be renamed and reused. The useful density contrast must exist at a particle size where the valuable mineral is liberated and can be handled practically.
We use this page as an entry point for minerals beyond the primary gold, tin, tungsten and chrome solutions.
Current assessment scope
Projects may include tantalum-niobium minerals, manganese, ilmenite, zircon and other heavy-mineral occurrences. The first review is intended to establish whether gravity testing is justified, what data is missing and whether another process route is likely to be necessary.
We do not publish complete pages for a mineral until there is enough real technical content and project relevance to make that page useful.
Send evidence before requesting equipment
Useful initial information includes mineral assays, feed size, known liberation observations, project tonnage, product targets and representative material photographs. If the deposit is poorly characterized, the next step may be a sampling or test plan rather than an equipment quotation.
Typical process logic
Open each stage to see the duty it performs. Test data can remove, add or change a stage before equipment is sized.
01 Confirm mineral identity
Use appropriate assays and mineral observations to establish what valuable and gangue minerals are present.
02 Check gravity amenability
Screen representative material by size and density response before proposing a plant route.
03 Define preparation needs
Determine washing, crushing, grinding, classification or desliming requirements.
04 Test staged separation
Evaluate roughing, scavenging and cleaning behavior on controlled streams.
05 Review project economics
Combine test mass balance, product requirement, throughput and site conditions before equipment selection.
Why equipment appears in the route
These are process duties, not a shopping list. Feed conditions and mass flow decide whether a machine belongs in the final scope.
Sample preparation
Creates representative, size-controlled test feeds and prevents a small rich fraction from distorting expectations.
Gravity roughing
Tests whether a meaningful heavy-mineral pre-concentrate can be produced at practical mass pull.
Concentrate cleaning
Evaluates whether gravity, magnetic or other physical methods can reach a useful product.
Dewatering and water return
Converts a laboratory route into a plant concept that can operate with the available water and tailings plan.
Frequently asked questions
Which additional minerals can you assess?
Typical enquiries include tantalum-niobium, manganese, ilmenite, zircon and mixed heavy-mineral deposits. Suitability depends on the actual mineral assemblage.
Does high mineral density guarantee gravity recovery?
No. Liberation, particle size, shape, gangue density and the required product quality can limit gravity separation.
What should I send for a first review?
Mineral identification or assays, representative photos, target capacity, feed size, project location, any existing test results and the intended product.
Project review
Send the ore facts before we size the more mineral solutions route.
Share the mineral, target capacity and what you already know about the feed. We will review the project within one business day.
