Gypsum Quality Comparison Report 2017
Pacific Fertiliser recently added more gypsum pits to a study it undertook in 2015 for detailed research into the bulk agricultural gypsum products available on the eastern seaboard of Australia. This research continues on from the NSW Department of Primary Industries work in 1996 which was reported in the AgFact AC.10 (Agdex 514) document.
The numerous gypsum samples were obtained from various agricultural gypsum sources either ex mine pit or from product landed on the farm. Pacific Fertiliser natural gypsum and REGYP recycled gypsum products were tested during the research and these were taken from our finished product stockpiles.
The main items we tested for were gypsum purity, sizing and solubility. The results enable us to benchmark our products against others, but also to help customers in their evaluation of which gypsum to use when they are looking to purchase gypsum for their farm or project.
When testing for gypsum solubility, we employed the method used in the AgFact AC.10 paper. This test method is more indicative of what happens in the paddock rather than the normal method to test solubility, where gypsum samples are finely ground up before being analysed. Due to the river bed gypsum having higher salt contents we had to adjust the solubility results to reflect the true gypsum solubility.

Test Laboratory:
Pacific Fertiliser commissioned Cement Australia to do the gypsum analysis work in 2015 through to 2017 for our research. Cement Australia’s laboratory in Darra QLD is NATA approved and very proficient and experienced in testing gypsum and other minerals.Test Methods:
Gypsum Purity:- Calculated from Sulphur (S) content. (18.6% Sulphur is 100% CaSO4.2H2O)
Sulphur Content: – X-ray fluorescence (XRF)
Total Calcium:- XRF
Total Oxides:- XRF
Moisture Content:- AS 4489.8.1, modified for gypsum by limiting heat to 40ºC for 24 hrs.
Particle Size:- Analysis Dry sieve
Gypsum Solubility:- As per the method used in the NSW AGFACTS AC.10. Solubility is expressed as electrical conductivity (EC) of solution obtained by adding the equivalent of 10g of pure gypsum (CaSO4.2H2O) to 1 litre of demineralised water. This solution is gently shaken (20 times end over end) and placed in a centrifuge for 10 minutes. The unit of electrical conductivity is dS/m.
Adjusted solubility:- Pacific Fertiliser added a modified column to the analysis results in the above table, to allow for the effect on electrical conductivity in the gypsum samples with a higher salt content. The measured electrical conductivity (EC) of a solution is influenced by the concentration and composition of dissolved salts. In the 1996 results Bourke solubility was 0.4 dS/m and Balranald was 1.0 dS/m.Please download a full copy of the research report here (17mB)

Buying Gypsum
When buying gypsum from any supplier please ask the following questions when requesting delivered or ex works prices.
- Price $/tonne
- Do you have a recent analysis report (less than 6 months old) including
- Gypsum purity (%)
- Calcium and sulphur content (%)
- Sizing (top and mean size)
- Salt content %
- Moisture content %
Gypsum Quality Classification:
- Premium Grade Gypsum described as : Gypsum must contain a minimum of 89% purity, 16.5% sulphur (S) and a minimum of 21.0% Calcium (Ca).
- Grade 1 Gypsum described as : Gypsum must contain a minimum of 81% purity, 15.0% sulphur (S) and a minimum of 19.0% Calcium (Ca).
- Grade 2 Gypsum described as : Gypsum must contain a minimum of 67% purity, 12.5% sulphur (S) and a minimum of 15.5% Calcium (Ca).
- Grade 3 Gypsum described as : Gypsum must contain a minimum of 54% purity, 10.0% sulphur (S) and a minimum of 12.5% Calcium (Ca).
Purity of gypsum is calculated by dividing the Sulphur content % by 0.186 (i.e. gypsum with 100% has 18.6% Sulphur).

Fine Gypsum Products Brisbane
Pacific Fertiliser is trailing a new gypsum refining process to offer a gypsum product ex Brisbane that has the following characteristics: Gypsum purity much higher than local mined sources with a solubility and fineness similar to super fine grade gypsum.
The Mine2 gypsum product is available ex Brisbane. Pacific Fertiliser continues to sell its other gypsum products from Port of Brisbane, Dinmore and Pinkenba.
NATA certified test results are available for the Mine2 and the rest of the PacFert gypsum range on request.
Please contact Pacific Fertiliser for information and samples.
