The National Gypsum Miners Association Inc. represents the interests of Australian Gypsum Miners. The purpose of our Association is to promote the Mining, Processing, Marketing and Use of Gypsum. Gypsum Mining is in Crisis. No new mines are being developed due to too much red tape and very high start-up costs.

Gypsum is a non-metallic mineral, found in rock form. It is composed of 79.1% calcium sulphate and 20.9% water, by weight. Chemists call it Hydrous Calcium Sulphate, and as there is one molecule of calcium sulphate combined with two molecules of water. It has the chemical formula CaSO 4 2H 2 0. By volume this works out to nearly 50% water in ...

Our Locations. Our five main manufacturing sites and Training Academies are located across the UK, and each one sits close to our mines. Gypsum is the vital raw-material at the heart of our plaster and plasterboard. As so much of it is mined, milled and made right here in Britain, we wanted to make sure we were close to those reserves.

An abandoned gypsum mine has been discovered beneath the route of a highway construction in Hunan province, south China. Due to the highway construction and operations safety, there is an urgent need for a comprehensive stability analysis of the abandoned mining area. The 3D laser scanning detection technique has been adopted, …

Gypsum mining poses certain health and safety risks to workers. The extraction and processing of gypsum can generate dust, including respirable crystalline silica, which can be hazardous if inhaled. Prolonged exposure to gypsum dust can cause respiratory issues, including silicosis and other lung diseases.

Gypsum Doesn't Have To Come From A Mine. It Can Be Made Too. The process of making American Gypsum's Synthetic Gypsum (FGD Gypsum) at our Georgetown, SC facility starts at our partner power plants, where SO2 gas (sulfur dioxide) is passed through limestone that is sprayed in the air pollution control scrubber stack. The resulting sludge …

In 1896, a plant was built in Paris, and gypsum rock was hauled by donkeys from the mines to the ground surface, where it was moved to the trains, which carried the rock to Paris for processing. In these early mining days, rock was blasted and the gypsum was mined by hand drills. In the mines, candles and oil lamps were used.
