Spent Carbon And Pelletized By-Products: From Super Sack To Split Sample.

Granulated and pelletized materials, including spent carbon and carbon ﬁnes, require a controlled sampling process because valuable metal may not be distributed evenly throughout the lot. Just Reﬁners begins with a clear, documented path designed to support a representative sample and a fair evaluation.

Represented weighing. Auger sampling. Mixed and split samples.

The Sample Must Reﬂect The Lot.

Carbon-based material is not always uniform from one part of a super sack to another. A sample taken from only one area may not give a useful picture of the material as a whole. The process is designed to collect, combine, and divide material in a controlled way before analysis.

Variable Metal Distribution

Precious-metal content can vary within a lot, which is why a deﬁned sampling method matters.

Material-Speciﬁc Sampling

The approach is designed for granulated and pelletized material such as spent carbon and carbon ﬁnes.

A Process You Can Follow

Clients or their chosen representatives are welcome during applicable weighing and sampling stages.

Clear Steps. A More Representative Sample.

01 Represented Weighing

In the presence of you or your representative, each super sack is removed from its pallet and placed on a certiﬁed industrial scale. Net weight is recorded and veriﬁed with clear visibility.

The exact sampling quantity, split distribution, handling protocol, and moisture-related procedure must be conﬁrmed by Just Reﬁners operations before ﬁnal production copy is published.

Conﬁdence Comes From A Process You Can Verify.

The purpose of the sampling path is not just to prepare material for analysis. It is to give every party a clearer basis for understanding what happens next and for discussing the information that follows.

A Combined Sample

Individual samples are brought together through a controlled preparation step before splitting.

Clear Sample Handling

Split portions are sealed and labeled as part of the agreed process, giving the material a clear path into analysis.

A Basis For Comparison

The process can support an informed discussion of assay information and the next commercial step.

Start With The Information You Have.

A clear ﬁrst conversation helps the team identify the practical next step for carbon-based material. Share what is already available. The team can clarify what else may be needed.

Material Type

Describe the material as clearly as possible, including whether it is spent carbon, carbon ﬁnes, or another granulated or pelletized by-product.

Approximate Volume

Provide an estimated quantity, bag count, or other practical indication of lot size when available.

Available Speciﬁcations

Share any relevant material information, prior assay information, or handling notes that may help the initial review.

Location And Timing

Let the team know where the material is located and any relevant operational timing considerations.

The Right Path Depends On The Material And The Next Step.

Questions About Granulated And Pelletized Material.

Why does spent carbon require a specific sampling process?

Precious-metal content may not be distributed evenly throughout a lot of spent carbon or carbon fines. The material is therefore sampled, mixed, and split through a controlled process designed to create a more representative sample for the next stage.

Can I or my representative be present during weighing and sampling?

Yes. Clients and their chosen representatives are welcome during applicable weighing and sampling stages. The team will confirm how representation applies to the material, location, and agreed process.

What is auger sampling?

Auger sampling uses an auger to collect material from beyond the surface and through the depth of an individual sack. This helps the team gather material from more than one point within the lot before the samples are combined.

What happens after individual samples are collected?

Individual samples are combined and mixed before being divided into labeled portions according to the applicable process. The resulting portions then follow the agreed analysis path.

What if my material is not carbon-based or pelletized?
