Approved
One independent standard, across the metals value chain.
From the mine face to the refinery gate to the trading desk, every actor in the non-ferrous and precious-metals trade needs one thing from a laboratory: analytical results they can trust completely. Accredited methods, a disciplined chain of custody and a century of independent rigour — that is what Bachelet has delivered since 1925.
Grade you can bank, from resource to offtake.
Mining companies · concentrators · producers of concentrates, doré & cathode
For a producer, everything downstream rests on the accuracy of the assay. Precise metal-content determination, reliable grade control and defensible moisture and transportable-moisture-limit figures all demand analytical discipline at every step. Independent, ISO/IEC 17025-accredited results give you numbers that hold up to any scrutiny.
- Independent assay for offtake settlement — a figure both buyer and seller trust.
- Moisture & TML determination for safe, compliant concentrate shipment.
- Grade control and check-assay programmes with full QA/QC traceability.
- Umpire referral when a result is contested downstream.
Payable metal in, penalties accounted for.
Smelters · refiners · metallurgical processors
A refinerie's decisions are only as sound as the analysis behind them. That calls for rigorous feed verification on receipt, precise determination of deleterious and penalty elements — arsenic, antimony, bismuth, mercury, selenium — and a mass balance you can defend across slag, matte and residue streams. Precision is the whole point.
- Independent feed verification to confirm what you are paying for.
- Penalty-element determination at trace level by ICP-OES and AAS.
- Slag, matte, anode-slime and residue analysis for recovery & mass balance.
- Fire assay for precious-metal payables in complex feeds.
Neutral ground for weight, quality and settlement.
Physical metal traders · merchants · offtakers
When two parties, two labs or two ports disagree, only an impartial, technically rigorous result can settle it. Bachelet acts as that neutral authority — from load-port inspection to umpire analysis and quality certificates — applying the same accredited standard whatever the cargo, the port or the counterparty.
- Recognised independent umpire & referee analysis for settlement disputes.
- ISO/IEC 17020 inspection, weighing & sampling at load and discharge.
- Quality & weight certificates for warehousing, collateral and financing.
- Fast turnaround to keep cargoes and letters of credit moving.
Value hidden in heterogeneous material — found.
Recyclers · secondary refiners · scrap, e-waste & residue processors
Secondary feed is the hardest material to analyse: spent catalysts, circuit boards, sweeps and mixed residues are wildly heterogeneous, and the metal of interest often sits in fractions of a percent. Representative sampling and precise, repeatable precious-metal recovery analysis are the whole game — exactly the discipline Bachelet is built on.
- Representative sampling & homogenisation of heterogeneous secondary material.
- Precious & PGM recovery by fire assay (Pb) and ICP-OES.
- Deleterious-element screening for downstream refining acceptance.
- Independent lot valuation both parties can settle on.
Whoever you are in the chain, the proof is the same.
Accredited methods, controlled chain of custody, and 100 years of independence — so a Bachelet certificate means the same thing to a miner, a smelter, a trader and a recycler.
