Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

Difference between data mining and DBMS?
A DBMS (Database Management System) is a complete system used for managing digital databases that allows storage of database content, creation/maintenance of data, search and other functionalities. On the other hand, Data Mining is a field in computer science, which deals with the extraction of previously unknown and interesting information from raw data. Usually, the data used as the input for the Data mining process is stored in databases. Users who are inclined toward statistics use Data Mining. They utilize statistical models to look for hidden patterns in data. Data miners are interested in finding useful relationships between different data elements, which is ultimately profitable for businesses.
DBMS
DBMS, sometimes just called a database manager, is a collection of computer programs that is dedicated for the management (i.e. organization, storage and retrieval) of all databases that are installed in a system (i.e. hard drive or network). There are different types of Database Management Systems existing in the world, and some of them are designed for the proper management of databases configured for specific purposes. Most popular commercial Database Management Systems are Oracle, DB2 and Microsoft Access. All these products provide means of allocation of different levels of privileges for different users, making it possible for a DBMS to be controlled centrally by a single administrator or to be allocated to several different people. There are four important elements in any Database Management System. They are the modeling language, data structures, query language and mechanism for transactions. The modeling language defines the language of each database hosted in the DBMS. Currently several popular approaches like hierarchal, network, relational and object are in practice. Data structures help organize the data such as individual records, files, fields and their definitions and objects such as visual media. Data query language maintains the security of the database by monitoring login data, access rights to different users, and protocols to add data to the system. SQL is a popular query language that is used in Relational Database Management Systems. Finally, the mechanism that allows for transactions help concurrency and multiplicity. That mechanism will make sure that the same record will not be modified by multiple users at the same time, thus keeping the data integrity in tact. Additionally, DBMS provide backup and other facilities as well.
Data Mining
Data mining is also known as Knowledge Discovery in Data (KDD). As mentioned above, it is a felid of computer science, which deals with the extraction of previously unknown and interesting information from raw data. Due to the exponential growth of data, especially in areas such as business, data mining has become very important tool to convert this large wealth of data in to business intelligence, as manual extraction of patterns has become seemingly impossible in the past few decades. For example, it is currently been used for various applications such as social network analysis, fraud detection and marketing. Data mining usually deals with following four tasks: clustering, classification, regression, and association. Clustering is identifying similar groups from unstructured data. Classification is learning rules that can be applied to new data and will typically include following steps: preprocessing of data, designing modeling, learning/feature selection and Evaluation/validation. Regression is finding functions with minimal error to model data. And association is looking for relationships between variables. Data mining is usually used to answer questions like what are the main products that might help to obtain high profit next year in Wal-Mart?
What is the difference between DBMS and Data mining?
DBMS is a full-fledged system for housing and managing a set of digital databases. However Data Mining is a technique or a concept in computer science, which deals with extracting useful and previously unknown information from raw data. Most of the times, these raw data are stored in very large databases. Therefore Data miners use the existing functionalities of DBMS to handle, manage and even preprocess raw data before and during the Data mining process. However, a DBMS system alone cannot be used to analyze data. But, some DBMS at present have inbuilt data analyzing tools or capabilities.
What are the main good points for limestone quarries?
Provides a few jobs locally. Lowers the cost of gravel roads if the quarry is in your area. A resource for gravel, limestone, and lime dust for property owners and farmers. Often times, when the quarry is finished the company is required to reclaim the land and make it look nice again. The quarry then becomes a park, or recreation area.
In the past, they didn't have to do this and that's where the bad image came from.
Where is azurite mined in Australia?
Azurite is mined in many areas in Australia where there are copper mines, including Broken Hill (NSW), Blaxand (NSW), Alice Springs (NT), Queenland (Mt Isa and Chillagoe), Mt Lofty Ranges (SA) and Whim Creek (WA).
Why are there salt mines in the Midwest?
please guys, I need help on my homework and the information provided by my teacher does not give the answer. thanks for your help! :)
Are hillbillies and rednecks the same thing?
No, they are different. (and not to condone name-calling or sterotyping, but there terms are obviously in the vernacular, so the following is simply an explanation of how they are used...)
A hillbilly generally refers to someone who lives in the mountains and is detached from popular culture by virtue of the geographical distance; they don't have any ideological objections to it. A redneck is often (but not always) from the southern regions of the U.S. and makes a decision to place less emphasis on education and culture even when it's available, and instead values simpler, more base pursuits like sex, driving and drinking (in various combinations).
What did Europeans do with the gold and silver that was mined from Mexico and Peru?
They bought and traded with Asia using the silver and gold mined in Mexico and peru.
What are the largest copper producers in the U.S.?
Three companies produce over 95 percent of U.S. copper: Phelps Dodge, Inc., Asarco, Inc. (owned by Grupo Mexico S.A. de C.V.) and Kennecott Utah Copper Corp.
Would an ore at earth's surface or an ore deep underground be more expensive to mine?
it depends mainly it depends what level you can mine usally the higher the level you need to mine then is how much there worth==the higher the level the more money
What stone is the hardest stone?
Diamonds is not a stone it's crystal actually.
But the hardest stone is granite stone.
When did Montana start the gold rush?
Early 1860s. The prospectors were mostly a combination of disgruntled miners that had failed in the California gold rush and Confederate deserters fleeing the Civil War. The first strike was at Gold Creek between Garrison and Dearlodge, but the rush quickly moved south to Nevada City and Virginia City. Helena, the state capital, was the site of one of the largest strikes and triggered its own gold rush in 1864.
How do you convert vertical shaft to horizontal shaft?
Their is one fairly basic way to modify a vertical shaft to a horizontal.
Since most motors (except two strokes) are only designed for vertical, they normally can handle being on their sides, so you have to do several modifications.
The gas tank and carb need to be rotated 90 degrees so they still operate.
You need to get lubrication to the crank, con rod, and piston.
I would do this by bolting a scoop to the con rod via the same bolts, made of moderate gauge sheet metal. Be sure t check the clearances so the scoop doesn't hit the sidewalls of the crank case and the timing gear/camshaft. If contact occurs you may end up having to junk the whole motor.
Why are chemical properties not always used to identify minerals?
Testing the chemical properties of a mineral might damage the mineral sample. Also, these tests can be complex and may require expensive equipment.
How does mining nickel ore cause pollution?
The machines companies use to mine the ore create polutive gases. There is likely a better answer and this one should not be taken seriously but it is an idea that spawns from your question and it can be researched and proven.
What are the main gold refining methods?
Two common methods are the Wohlwill process and the Miller process.
