William Bradley Mr. Leavitt Economic 12-16-2016 Tata Green River, Sweetwater County,Wyoming is the trona capitol of the world. Trona is used for many things all over the world. Tata began making soda ash in 1968. Every year, Tata mines 4.5 million tons of trona. Tata employs many people in various jobs, in their plant and mines. It is one of the biggest employers in Green River,Wyoming. The trona that they mine and process, is sent by truck ,train or shipped all over the world. There are five plants mining and processing trona in Green River. Productions Materials The trona is mined from underground. People and equipment get in the mine from a hoist that takes them down 1,600 feet to the mine. They are taken to the front of the mine where they remove the trona and send it to the surface. They use railroad cars, trucks, and boats to send it to buyers all over the world. Processing: On the surface, the plant converts trona ore to soda ash. They use a multi step cleaning process. The trona ore is first crushed and screened to prepare for processing. A kiln heats the crushed trona to drive off gases. This process changes ore to sodium carbonate. It is combined with water and filtered to remove pollution. The water is taken out, which forms a soda ash crystal slurry. Than it is put into a machine to remove the rest of the water. Then they are sent to round dryers. The dried product is stored in bins, until shipped by trucks or rail cars.
