Full Scalability

Parallel batch processing allows:
productivity gains at every workload level

● Blocks fully exploit Fire Assay's  inherent
parallel processing capabilities

Graded path to mass analysis stage

Higher accuracy  - Samples, duplicates and standards undergo same ambient  conditions

Save hearth space -  More assays per batch

Save time – reduce manipulation hazards
Better stability – due to larger base
Assays keep array – no misplace errors

 (+) Assay of Ores  Stocked (red) / Non-stocked (grey) ● "Pt" = Press Type ● "Ab" = Absorption : g (PbO) / hole ● "ML": Multi-Loader Tool

 

†  Microcupellation

‡   Bevelled Blocks

Shorter processing time

Fewer amount of Reagents

Less destructive method

10 mg sample  + 2 g Pb foil

Scrap  taken at hidden places

Still high accuracy

Bevels allow  lifting  from under

No damage from tongs squeeze

Fork takes blocks without clamping

~10% less weight & thermal inertia

Fork may  handle several blocks

Increased heat exchange surface

 

 

Tools   

Forks ( BF - TF)

Multi-Loaders (ML)

Purpose designed

Take 1 to 4 bevelled blocks in / out of furnace all at once

Charge many samples across several blocks all at once
