The Berkeley Pit at Butte, the largest truck-operated open pit copper mine in the United States, is sometimes called the most productive three square miles in "Montana. Started in 1955, the pit now accounts for more than 80 per cent of the total copper production from this famous mining district. As it increased production, the tin-' derground mines gradually were phased out and the last deep-vein ore operations ceased in late 1975. The pit has taken away a large portion of the hill that earned the nickname of "The Richest Hill on Earth" however, it has produced more than 230 million tons of copper .ore at the rate of about 50,000 tons per day from 190,000 tons of earth. The billionth ton of material was removed in November 1976. Enough blasting is done each day to keep the mine's electric shovels busy filling huge 60-to-100-ton ore-hauling trucks. Ore containing higher percentages of copper is taken . to the. Clyde E. Weed Concentrator near the Pit where it is crushed to the size of walnuts, ground to powder and concentrated. The concentrate is shipped to the smelter in Anaconda by company railroad. Copper-bearing solutions ex-tracted from waste material in leach dumps are sent to the precipitation plant, where scrap iron cones collect the on. This precipitate also, is sent to the smelter. The Anaconda Co. offices, mine, concentrator and smelter operations employ a total of 4,500 persons. The firm, which played a large part in Montana history, now is a sub sidiary of Atlantic Richfield and 'is the largest employer. properties later became the taxpayer and consumer in the giant Anaconda Co. state. i Minerals display free There are a number of cases arranged according to the Hey classification, which gives a different number to each mineral based on its chemical composition. A display of fluorescent minerals is exhibited in a separate room under ultraviolet lights. There are exhibits of Butte and Montana minerals as well. The museum is on the second floor of the Library Museum Building, situated at the southeast corner of the Tech campus. Guided tours can oe af-ranged by contacting the Montana Bureau of Mines at Tech, 792-8321.
