For mining projects, mineral processing testing often involves complicated, fragmented procedures.
From ore delivery and sample preparation to testing operations and report issuance, a poor connection between multiple stages causes time waste, inaccurate data, and operational errors.
Based on standardized in-house procedures, this article introduces Xinhai’s full-cycle mineral processing test services.
We explain how our one-stop model eliminates complicated coordination and helps clients cut early trial costs to accelerate mine project progress.
After signing the test contract, clients only need to deliver raw ore or tailings to Xinhai.
Our professional team takes charge of all subsequent procedures with no extra work required from your side.
Dedicated coordinators update sample receiving and processing progress in real time, ensuring efficient and worry-free cooperation.
Raw Ore: Bulk ore is crushed to 2mm and prepared in standardized procedures.
Qualified assay samples, sieve analysis samples, and processing test samples are produced to guarantee representativeness.
Tailings: Without crushing, tailings are mixed, screened, and purified to remove impurities before sample preparation.
Multiple Ore Samples: Each material is processed independently without mixing or omission.
All operations follow CNAS laboratory standards.
Key element testing (Au, Ag, Cu, Pb, Zn, Fe) is available with internationally recognized CNAS-accredited reports.
Exploratory Test: Multiple preliminary processing schemes are compared to determine the optimal technical direction.
Condition Test: Key parameters, including grinding fineness, reagent dosage, pulp density, and water quality influence, are optimized.
Flowsheet Test: Complete processing flowsheet verification with optimized operating parameters.
Closed-circuit Test: Core industrial verification to achieve balanced yield and technical indicators.
Note: Closed-circuit testing is mainly applied to flotation processes; gravity separation and magnetic separation generally do not require middling return.
Auxiliary Test: Including concentrate and tailings multi-element analysis, particle size analysis, and settling tests for thickener selection.
Pilot Connection: For projects requiring semi-industrial tests, pilot preparation and equipment commissioning start synchronously with lab testing, ensuring consistent indicators and stable 72-hour continuous operation.
After test completion, professional researchers compile detailed test reports, reviewed and approved by senior engineers.
Complete data, clear flowsheet records, and CNAS-accredited testing items support concentrator design and feasibility study application, suitable for both domestic and international mining projects.
Q1: What types of ores can you test?
Xinhai’s professional laboratory provides processing tests for more than 70 minerals,
covering ferrous and non-ferrous metals such as gold, silver, copper, lead, and zinc, as well as non-metallic minerals including fluorite, quartz, and feldspar.
Q2: Can your test reports be used for concentrator design?
Yes.
All test data and reports comply with international standards.
CNAS-accredited testing items are globally recognized, fully applicable for engineering design, project approval, and overseas investment projects.
Q3: Do you provide semi-industrial pilot services?
Yes.
Xinhai owns a 2,000 ㎡ professional pilot test center to provide complete semi-industrial trial services.
One-stop Full Service: All procedures from ore receiving to report delivery are fully managed by our team, saving communication costs and shortening project cycles.
CNAS Standard Operation: Standardized sample preparation and testing guarantee accurate, repeatable, and internationally recognized test data.
Customized Test Scheme: Flexible solutions for different budgets, ore characteristics and project scales, including exploratory test, full lab test and pilot docking services.
Professional Technical Team: Senior mineral processing engineers optimize technical parameters and solve various difficult mineral processing problems, with professional report interpretation support.
Authorized & Applicable Reports: CNAS-accredited detection indicators are widely accepted globally, meeting engineering design and official declaration requirements for global mines.
Xinhai’s integrated mineral processing test service simplifies complex testing procedures,
effectively reduces early trial-and-error costs and technical risks for mine development.
Whether you need cycle evaluation, cost consultation, or customized testing solutions,
our team provides one-to-one professional support to ensure efficient and stable project implementation.
