The mine development plan for Ace was approved by Newfoundland's Department of Natural Resources in early 2018. Gypsum has been mined by open-pit quarry in this area since the 1950's with historical production estimated at approximately 15 million tonnes. Gypsum mining is environmentally friendly and leaves behind no toxic tailings.
The Solution: CraneWerks designed a bridge that was built in two pieces so it could fit down the narrow mine shaft before it was welded together at the bottom. The crane provides a lifting solution on a daily basis, raising mobile equipment components, typically weighing approximately 10 tons, around the area. U.S. Gypsum explained that loads are normally large pieces of …
Fishtail gypsum on a matrix photo provided by Collector's Edge Minerals – @collectorsedgeminerals. Fishtail gypsum has a unique pattern that resembles the tail of a fish. This happens because the gypsum crystals grow in a way that they split and fan out into two directions, creating a shape that's a lot like a fishtail.
In this process gypsum is crushed, dried, ground, and calcined. Not all of the operations shown in Figure 11.16-1 are performed at all gypsum plants. Some plants produce only wallboard, and many plants do not produce soil conditioner. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. As
More than 5 million tons of gypsum is mined in Oklahoma annually involving 22 companies strung out across seven western counties. Major County is the leading state source of gypsum, producing more that 1.7 million tons a year. Figures from the U.S. Geological Survey show Oklahoma leading the nation in gypsum mining and in gypsum food additives.
To move materials around a mine site, workers need heavy-duty trucks. Also known as off-highway trucks, large mining trucks include both powerful mechanical models and environmentally friendly electric drive models.. Unlike conventional trucks, these mining vehicles have extra-large tires to support the heavy loads over uneven terrain commonly found around …

stripping in open pits (see photo below). After mining, the gypsum is processed into a variety of products, the most common of which are wallboard and plaster-of-Paris. To produce wallboard, the gypsum is "calcined," an industrial term for the process that includes the grinding of gypsum to a fine powder which is then heated for 2 to 3 hours.

The current mining method can only access 7 years reserve life at forecast rates of extraction. The bulk of the remaining reserve is thinner seam (2.0m to 2.25m) and cannot be mined using the existing mining methods and machines. It was proposed to purchase sufficient low height mining equipment to establish a thin seam mining districts.
Gypsum has been mined in Nova Scotia for over 200 years and the province has traditionally been one of the world's largest suppliers of gypsum. Gypsum's main use is as an ingredient in wallboard, or drywall. At the world's largest surface gypsum mine in Milford, Nova Scotia, the bones of two different mastodons were discovered in 1991 and ...
