Sample Preparation - South Africa
SORTING AND DRYING
Sorting and boxing of samples received as pulps in:
| Paper packets | $1.20 per sample |
| Plastic bags | $2.00 per sample |
| Sorting and drying of samples prior to preparation | $0.60 per kg |
(Applies only to consignments that are neatly packaged and labelled. Sample Submissions poorly labelled or packed will incur additional sorting charges.)
PRIMARY CRUSHING
| Conventional Jaw crushing to nominal minus 10 mm | $0.50 kg |
| Boyd Jaw crushing to nominal minus 2 mm | $1.50 kg |
(Includes simultaneous rotary splitting if required)
PULVERISING
Most devices used in the crushing and pulverising of samples can impart trace levels of contaminants to the samples for analysis. Low chrome steel is the preferred material for pulverising bowls as the iron contamination is usually negligible compared with the iron levels commonly encountered in most geological materials.
Genalysis aims to achieve 85% minus 75µm using a single stage mix and grind, however the hardness of some samples is such that this may not always be achieved using standard pulverising protocols. The maximum size sample the mills can pulverise efficiently is 3kg. If fine grind is essential please discuss sample preparation options with Genalysis prior to commencement of any project.
| (a) up to 300g (chrome-steel bowl) | $2.00 sample |
| (b) greater than 300g, up to 750g (chrome-steel bowl) | $4.00 sample |
| (c) greater than 750g, up to 3000g (chrome-steel bowl)[standard 4 minute grind] | $6.00 sample |
| (d) greater than 3000g (chrome-steel bowl) | price on application |
| Cleaning of pulveriser after sample with gold free quartz | 75% of cost of pulverising |
SIEVING
| Dry screen partial or total sample to specified mesh size(s) | $35.00 hour |
| Wet sieving (to client's specification) | $35.00 hour |
| Reporting weights of samples "as received" or weights of fractions recovered | $1.60 per weight |
SPECIAL PREPARATIONS
| Riffle splitting | $35.00 per hour |
| Compositing of specified samples | $35.00 per hour |
| Client specified preparation (technician time) | $35.00 per hour |
FREIGHT
(Johannesburg to Perth)
| Air freight of standard Genalysis prepared assay pulp (~150g) to Perth | $1.95 per pulp |
Air freight of samples received as pulps or not requiring preparation. | At consolidated rates |
| Genalysis will consolidate freight on a regular basis, therefore offering freight at significant discount rates. | |
| Urgent freight consignments to Perth | At cost |
Please note that freight ex-Johannesburg is not subject to client related discount.
SAMPLE STORAGE
All solid samples (assay pulps, bulk pulps, and residues) will be stored without charge for 60 days after completion of analysis. After this time all samples will be stored at a rate of $3.00 per cubic metre per day until the client's written advice regarding return, collection or disposal is received.
Expenses related to the return of samples will be charged at cost.
Disposal of samples is charged at $75.00 per cubic metre.
Retrieval of random samples from storage (i.e. not complete job lots) for further analyses or return to clients is charged at $75.00 per hour.
