Web-based data set Process of Data Mining Data Mining is a comparatively new technology to determine the futuristic trends. Data Mining tends to extract out valuable information from large unused data using statistical techniques or by using techniques of artificial intelligence and machine learning. The extracted data can be used to increase the sales, grow the business, to analyze the market trends and also in fraud detection. Students working on Ph.

Butte[ edit ] Montana's leading silver district was Butte, which produced million troy ounces of silver from through Inthe gold placers were largely exhausted, and Butte was becoming a ghost townwhen silver ore was discovered, starting a rush to the district. Inthe first rich copper vein was discovered, and copper mining at Butte proved to be much more profitable than silver mining.

Also inthe Northern Pacific Railroad laid tracks into Butte, greatly aiding the economics of mining on a large scale. Mining halted at Butte inbut inMontana Resources LLP reopened the Continental open pit just east of Butte, and so silver continues to be produced at Butte, as a byproduct.

Geology[ edit ] The ore deposits in Thesis a mining company were of very rich, but of very limited depth. Two factors contributed to this particular formation of the ores. The first of these factors were ascending hot waters traveling through fissures in the rocks and dropping their silver in chemically favorable zones.

The second of these were descending cold waters trickling down the fissure veins, and moving and re-depositing the silver to further enrich the veins near the water table. The first cause on the national levelin response to miners calling for the government to subsidize silver, was the Bland—Allison Act of Within Montana, the introduction of railroads was a large factor in the silver boom.

For one, railroads allowed for ores to be transported to outside smelters and markets much more cheaply than was previously possibly. Secondly, transportation made it much cheaper to build mills and smelters near the mines because a large-scale transportation of materials was economically feasible.

InMontana's smelting centers reported record numbers in tons of ores per day: The two main producers of silver were Silver Bow County the Butte districtwhich produced In order to continue the silver boom, the government passed the Sherman Silver Purchase Act in This act mandated that the government purchase a minimum of 4.

Silver mining in Montana peaked inwhen Montana mines produced 19 million troy ounces of silver. After the Panic ofwhich was partly blamed on an overabundance of silver coinage, President Grover Cleveland called an emergency session of Congress, which repealed the Sherman Silver Purchase Act.

This caused the amount of silver purchased to drop abruptly. In Montana, many silver orebodies contained silver-enriched zones restricted to within a thousand feet of the surface, as shallow as a few hundred feet at some mines.

Once mining went below the silver enriched zones, the silver content decreased dramatically. As the zinc content approached and exceeded 30 percent, the ore became uneconomic to mine.

Applications of Data Mining

Lower silver grade, increased zinc, and the increased expenses of pumping water from the deeper mine levels forced the Elkhorn mine to close down in The Granite-Bimetallic mines shut down in September because they had exhausted the ore. Additionally, the Alice, Lexington, Moulton, Alta, and Comet mines closed between and because of low silver prices following repeal of the Sherman Act.

Some mines, such as the Hope and Castle mines, were able to remain open into the early s due the discoveries of new orebodies, but they had little success. The copper mines at Butte, which produced considerable silver along with the copper, continued to prosper regardless of the price of silver.

In the mids, the zinc which was a costly nuisance in the s became valuable, and the deep levels of old silver mines became zinc mines, and produced the silver as a byproduct.
