This project proposal relates to the potential for mining a vast gypsum deposit located adjacent to Sceale Bay, about 14 km south of Streaky Bay on the west coast of South Australia. Preliminary estimates put the ore reserves of gypsum of 88% purity...

The Copper King orebody, located approximately 10 miles north-northeast of Beltana township, is a massive deposit of iron carbonate, the upper portion of which has been altered by oxidation and hydration to oxides of iron. The deposit was worked...

Plaster of Paris had been made from Cooke's Plains gypsum as mined. This report describes laboratory tests to improve the quality of the gypsum and plant runs to check the standard of plaster that could be made.

This report gives details of tests made to beneficiate granular gypsum ("caso"), which is at present regarded as overburden on the rock gypsum deposits at Stenhouse Bay, into a product suitable for the making of plaster.

Fred Ingham & Co., Plaster Manufacturers, Port Pirie and Dudley Park have sought Departmental assistance in locating a fresh source of gypsum of sufficient size and quality to satisfy a requirement of 10,000 tons per annum for plaster manufacture...

Fourteen power auger holes and three bulldozed cuts have indicated clay containing 45% gypsum under 1m of overburden. Reserves in MLs 661 and 662 on the west margin of a dry lake approach 100 000 t of washed gypsum. Saline water is likely to occur at...

Approximately 690 gallons of water containing 30 grains per gallon total sodium and potassium chlorides similar to the composition of the local water supply, would be required to produce a concentrate containing 0.1% or less total chlorides from the...

An inspection of a gypsum deposit in the area of a claim pegged by Mr. R.G. Law of Bookabie was made on 12th September 1962. The deposit is situated approximately 40 miles north of Bookabie.

Auger boring on a gypsum dune north-east of Morgan has proved 1 000 000 cubic metres of crude gypsum. Total reserved within MLs 665 and 678 exceed this value as the gypsum extends outside the area tested. 300 000 cubic metres of flour gypsum,...

Mapping of the Coober Pedy Opalfield has shown that opal occurrence, although erratic, is not entirely unpredictable. Several groups of workings are present in an area of about 150 square miles. The host rock is a distinctive pink and white...

Since the days of early settlement in South Australia mineral production from Yorke Peninsula has made an important contribution to the wealth of the state. Firstly, with the discovery and mining of copper in the Moonta Wallaroo district early in...

Gypsum resulting from the weathering of slate occurs in two places along a creek-bank near the surveyed township of "Amyton". Mottled red and white clay contains only 25 to 34 percent gypsum; the deposit is thus considered to be uneconomic.

The raw gypsum contains 86.3 per cent. CaSO4.2H2O. This figure could not be improved by the conventional washing methods tried. The light brown colour of the raw material is not improved by washing. Colour determinations of the calcined fractions show...

Examination of gypsum material from the Streaky Bay area indicated that a gypsum concentrate assaying 95.1 per cent CaS04.2H20 could be obtained by simple washing and classification. Recovery at this grade was 82.2 per cent. Cyclone separation of the...
