Sample Preparation - Australia
Samples submitted for ppb detection of gold are prepared in dedicated facilities, completely separate from samples submitted for ppm detection. Such separate facilities exist at our Maddington, Kalgoorlie and Adelaide locations.
SORTING AND DRYING
| Sorting and boxing of samples received as pulps | $75.00 hour |
| Sorting and drying of samples prior to preparation | $0.50 kg |
(Applies only to consignments that are neatly packaged and labelled. Sample submissions poorly labelled or packaged 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)
FINE PULVERISING - Conventional Preparation Systems
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.
The tungsten-carbide bowl will add substantial amounts of both Tungsten and Cobalt to the sample.
The zirconia bowl will add substantial amounts of Zirconium and Hafnium to the sample.
| (a) up to 300g (chrome-steel bowl) | $2.00 sample |
| (b) greater than 300g, up to 750g (chrome-steel bowl) | $3.50 sample |
| (c) greater than 750g, up to 3000g (chrome-steel bowl)[standard 4 minute grind] | $5.00 sample |
| (d) greater than 3000g (chrome-steel bowl) | price on application |
| (e) up to 100g (tungsten-carbide bowl) | $7.00 sample |
| (f) up to 100g (zirconia bowl) | $10.00 sample |
| Cleaning of pulveriser after sample with gold free quartz | 75% of cost of pulverising |
AUTOMATED PREPARATION – Robotic (Available at Maddington only)
Genalysis can offer preparation of samples via our state-of-the-art automated sample preparation system. This multi-function preparation system is capable of handling bulk samples up to 10kg with crushing capacity to nominal -2mm, with a grind capacity of 300g to 1.2kg. Genalysis will automatically initiate the use of one barren quartz wash between samples for all jobs unless otherwise instructed.
| a) single stage mix and grind 300g, up to 1.2kg [ROBSSMGQ1] | $3.10 sample | |||
| b) crush, single stage mix and grind 300g, up to 1.2kg (rock/core) [ROBCRB, ROBSSMGQ1] | $3.50 sample | |||
| c) crush, single stage mix and grind [ROBCRB, ROBSSMG] [ROBCRB, ROBSSMGQ1] [ROBCRB, ROBSSMGQ2] [ROBCRB, ROBSSMGQ3] | ||||

SPECIAL HANDLING – RADIOACTIVE SAMPLES
Samples will be monitored by Genalysis.
| Samples requiring preparation | Additional charge of $0.60 per sample |
| Samples received as pulps | Additional charge of $0.30 per sample |
*** NOTE: Charges are in addition to standard preparation costs. ***
By regulations, all radioactive material must be returned to the company, at their expense.
