The preparation of the gypsum used to evaluate the particle size effect on sphalerite contact angle was carried out as follows: a sample of 5 g of reagent grade gypsum was dryground in an agate mortar during 5, 10 and 20 min to obtain different size fractions. The samples were characterized with the aid of a Coulter LS100 particle size analyzer.
This paper reviews the problems of constructing on gypsum/anhydrite and their engineering significance and provides short case histories to illustrate some of the problems encountered.
Phosphogypsum (or "gypsum"), a radioactive material, is a byproduct of this process. Because it cannot be disposed of in the usual way, gypsum is stored in huge piles, called gyp stacks that cover 600 acres and rise to 200 feet. In the flat topography of Florida, they look like small mountains.

Large gypsum deposits, estimated to contain reserves of 220 million tons, were found along the Red Sea coast. Reportedly of high purity, the ore was mined mainly north of Port Sudan. In the late 1980s, about 20,000 tons were produced annually, about 6,000 tons by the Sudanese Mining Corporation and the remainder by private operations.

Two of the byproducts of coal combustion include gypsum and bottom ash. Bottom ash can be used as a component of concrete blocks and gypsum can be used in plaster or as a soil conditioner. In this process, the reclaimed gypsum and bottom ash is transferred via front end loaders to KWS hoppers with twin massflow screw feeders.

The Edlington Formation (Middle Permian Marl) comprises interbedded mudstones and gypsum passing down into massively bedded gypsum and anhydrite at the base. Both the formation and the gypsum beds thicken eastwards, with 20m of anhydrite overlying 13m of gypsum at Ure Bank.
The very soft sulphate mineral, gypsum, is widely mined throughout the world. It is one of the main constituents of plaster and is a wonderful soil conditioner and fertiliser found to be very valuable in the agricultural industry.
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing t in 2008.
