Define the purchase decision
Limestone wash-water procurement should preserve the actual fines and water chemistry. Naming the rock does not fix a universal anionicity, molecular profile or consumption rate.
Keep the proposed product identity connected to the tested suspension and the intended separator.
Keep water and fines representative
Record rock and clay contributions, wash flow, fines, pH, hardness and conductivity where available. Use the established recycle stream rather than assuming fresh laboratory water is equivalent. Collection and splitting should keep the fine fraction distributed consistently.
The water comparison distinguishes hardness-related changes from differences in the sampled solids.
Avoid one-property ordering
Compare adjacent profiles with supplier methods identified. Calcium-related interactions are a reason to test, not a universal argument for the highest charge. Keep stock preparation, active-dose basis and mixing history controlled while the candidate set changes.
Use the product profiles as screening categories and retain the actual commercial code behind the selected response.
Accept the handling outcome
Measure clarified-water fines, settling and settled material withdrawal. Include filtration or pumping where sludge handling limits water recovery. A fast interface and a small-looking bed do not by themselves prove reliable discharge at the required production rate.
Compare supplied-product cost using qualified consumption and the actual handling consequence, not a generic recommended dose.
Check a misleading apparent improvement
If a limestone candidate changes rank when established recycle water replaces makeup water, preserve the chemistry difference and repeat on matched fines. Neither the original sample nor the later test should be discarded merely because it complicates purchasing. The award must identify the water regime that the installation actually needs.
Retain the comparison conditions and any unresolved acceptance requirement with the proposed purchase.
Set the release boundary
Approve the tested feed and recycle-water range. Changed clay content, water source or chemical additions should prompt confirmation before extending a previous limestone-specific qualification.
| Purchase requirement | Required evidence | Release condition |
|---|---|---|
| Representation | Fines and actual water record | Trial reflects the wash circuit |
| Grade | Method-aware adjacent profiles | Selection is evidence based |
| Handling | Water quality and withdrawal | Award fits the complete duty |
