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 |
FINE PULVERISING
Fine pulverising of sample. Genalysis aims to achieve 85% minus 75µm however the hardness of some samples is such that this may not always be achieved using standard pulverising protocols. 3kg is realistically the maximum size sample the mills can pulverise efficiently. If fine grind is considered essential, please discuss sample preparation options with Genalysis management prior to commencement of any project.
Most of our "chrome-steel" pulveriser bowls are in fact "low-chrome" and typically add a few tens of ppm chromium to the sample, contrasted to higher chrome steels which may add hundreds of ppm chromium to the sample. Minor traces of Nickel, Manganese, Molybdenum and Vanadium are also probable.
| (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 |
| Any other client specified preparation schemes |
$35.00 per hour |
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 |
REMEMBER: CORRECT SAMPLE PREPARATION PROCEDURES ARE AN ESSENTIAL PREREQUISITE FOR QUALITY ANALYSES.
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. Genalysis will consolidate freight on a regular basis, therefore offering freight at significant discount rates. | At consolidated rates |
| Urgent freight consignments to Perth | At cost |
Please note that freight ex-Johannesburg is not subject to client related discount.
