Content Headlines of CD ROM

• Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O
• It is a by-product of phosphate which is used as fertilizer. 
• This gypsum must be hauled from the phosphate field for further processing into wallboard.
• Gypsum contains the plant nutrients sulfate and calcium, both of which may be deficient in sandy soils.
• Technically speaking, gypsum is a naturally occurring hydrated salt of calcium and sulfate (CaSO4-2H2O).
• Practically speaking, gypsum has uses beyond most people's imagination.
• Gypsum is an abundant mineral that was formed millions of years ago due to evaporation of shallow seas.
• Gypsum is generally found underground near deposits of limestone or other minerals formed by evaporation. 
• One of the most common forms of raw gypsum is a pure white crystal called alabaster. 
• Another form of unprocessed gypsum forms in desert terrain and its crystals resemble the petals of a flower. 
• For this reason, many people refer to this form of calcium sulphate as the 'desert rose'.
• Gypsum is typically mined in an open pit quarry.  The process used to mine gypsum is very similar to that used in many other rock quarries.
• First the exposed gypsum is fractured by drilling and blasting. The fractured gypsum is then loaded onto trucks and transported to a processing plant.
• At the processing plant, the large gypsum ore is reduced in size by passing it through a large crusher.
• Crushing the ore generates a mixture of smaller rocks that can be cleaned and sorted by size. 
• Sorting is accomplished by passing the gypsum through a series of vibrating screens. 
• Sorted rock is then loaded for distribution to be further processed by the end user.
• Once a gypsum mine has been depleted of all of its ore, the mine is then "reclaimed". 
• This process involves returning the land to a state that is better than it was before the gypsum was removed. 
• Harrison Gypsum Co. takes pride in its reclamation efforts, and is committed to returning mine sites to a state of usefulness.
• In 2000, gypsum output was 
  more than 25 million tons, and was valued at $175 million. 
• The top producing US states were Oklahoma, California,  Iowa, Texas, Nevada, Michigan, and New Mexico. 
• These states accounted for 75% of the total output. 
• The top three gypsum producing countries are were the United States, Australia, and Canada.
• The Asian market for gypsum and anhydrite continues to drive demand, with 36% of total world consumption and a growing demand of 3% per year. 
• Demand for gypsum has grown along with the booming housing market. About 60 percent of customers are residential builders, the rest are commercial builders
