Diamond Mines And Mining Techniques

Diamonds remain to this day a mystical gem with a somewhat checkered past. The story of the Hope diamond is based on a long legend of misfortunes supposedly befalling its various and colorful owners. Segregation and mistreatment of blacks in diamond mines in Africa has long been a terrible mark on humanity in that part of the world. Although early white miners were treated better the working conditions endured by all diamond miners were less than humane. Fortunately most of today's mines while still depending on human labor have most of the heavy work done with machinery.

Contrary to popular belief diamonds are mined in areas other than Africa. Some of the better known diamond mines are these.

* Argye one of the Rio Tinto company mines is located in Western Australia.

* Diavik another Rio Tinto mine is located in Canada.

* Ekati owned by BHP Billiton and located in the Northwest Territories of Canada.

* Baken owned by Trans Hexis is located in South Africa.

* Merlin owned by Striker Resources is located in Australia.

* Orapa owned by a partnership between DeBeers and the government of Botswana is in Botswana.

* Premier owned by the De Beers Company is located in South Africa.

Diamond ore is extracted from these mines using basically four mining techniques which are based on the type of geology in which the diamond bearing material is located.

Marine Mining is the most recent development introduced about 1990. This technique is similar to deep water oil drilling. A large shaft is bored into the seabed to a depth where diamond bearing soil is located and that material is sucked to the surface. Also underwater vehicles called "crawlers" move along the seabed to scoop up diamond bearing gravel and pump it to the surface.

Placer Diamond Mining is a technique that is seen many times in movies of the old West. The diamonds are buried in river banks or mountain sides and water canons are used to wash the material down to be processed.

Hard Rock Diamond Mining is again familiar to movie fans as they watched coal miners or gold and silver miners digging their way into deep underground tunnels. Of course the technique is modern now and makes use of many specialized machines to do the heavy work.

Open-Pit diamond mining is similar to the pit coal mines of West Virginia and some western states. Overburden which is the soil covering the diamond embedded material is moved by machinery and blasting. The diamond bearing material is then moved to processing plants. This technique is common when the diamond bearing material is found close to the surface of if the geology is so unstable that tunneling is not safe or practical.

From this short article it should be apparent that diamonds take long and interesting journeys before they find a cherished spot on your finger or ear lobes.

Data Mining vs Screen-Scraping

Data mining isn't screen-scraping. I know that some people in the room may disagree with that statement, but they're actually two almost completely different concepts.

In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to analyze information. That's a pretty big simplification, so I'll elaborate a bit.

The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. Screen-scraping was used to extract characters from the screens so that they could be analyzed. Fast-forwarding to the web world of today, screen-scraping now most commonly refers to extracting information from web sites. That is, computer programs can "crawl" or "spider" through web sites, pulling out data. People often do this to build things like comparison shopping engines, archive web pages, or simply download text to a spreadsheet so that it can be filtered and analyzed.

Data mining, on the other hand, is defined by Wikipedia as the "practice of automatically searching large stores of data for patterns." In other words, you already have the data, and you're now analyzing it to learn useful things about it. Data mining often involves lots of complex algorithms based on statistical methods. It has nothing to do with how you got the data in the first place. In data mining you only care about analyzing what's already there.

The difficulty is that people who don't know the term "screen-scraping" will try Googling for anything that resembles it. We include a number of these terms on our web site to help such folks; for example, we created pages entitled Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I suppose "scraping" is sort of like "ripping"). So it presents a bit of a problem-we don't necessarily want to perpetuate a misconception (i.e., screen-scraping = data mining), but we also have to use terminology that people will actually use.

4 Types of Mining and Quarry Equipment

You've surveyed the land, spent hours of painstaking research planning the process, and now you are ready to take your mining to the next level. The next phase of the journey will involve the proper equipment. There are several different types of equipment that go into mining. This article will cover some different types of mining equipment to get you started; and if you've already started, it will provide you with valuable knowledge to upgrade your equipment in the future.

Vibrating Feeder

A vibrating feeder is a type of linear direction feeding equipment. Vibrating feeders are widely used in mining and quarry operations and offer several features. Its features include smooth vibrating, dependable operation, and lengthy service life; most importantly, vibrating feeders are suitable for feeding. It consists of a vibrating frame, vibrator, spring, motor vibrating device and motor. The motor causes the vibrating feeder's shafts to rotate, which produces massive power and forces the feeder to vibrate. As the feeder vibrates, materials pass through its funnel and are screened. Common feeder applications include chemicals, minerals, coal, aggregates, and industrial materials.

Permanent and Self Cleaning Magnets

Both permanent and self cleaning magnets can be used on conveyor belts. A permanent magnet is built from a material that is magnetized and creates its own constant magnetic field. Permanent magnetic separators are used on conveyor belts when only limited levels of ferrous metals are expected to pass through. Self cleaning magnets are based on the technology of permanent and electro magnets. The purpose of self cleaning magnetic separators is to automatically remove and separate metallic and non metallic materials.

Forklifts

A forklift is an essential piece of equipment to any mining operation. Industrial forklifts can efficiently move mining supplies and material. Rough terrain forklifts can handle rugged conditions and still manage to perform well. With the standard attachments, a forklift can scoop, grip, pull, lift, scrape, clean, and load almost anything on a mine. Forklifts are extremely versatile and will increase the efficiency of your mining process.

Earthmoving and Construction Equipment
Earthmoving and construction equipment are essential to any mining or quarry operation. This equipment is often used in construction, turf, and excavation work. Examples of earthmoving and construction equipment include: backhoes, bulldozers, and dumpers. A backhoe loader is used for a wide range of jobs including excavating or breaking asphalt. A backhoe loader is a tractor with an arm linking a bucket to the front and a second arm attaching a backhoe in the rear. One benefit of a backhoe loader is that it is fairly small and versatile. A bulldozer is used to push heavy loads like sand from a demolished structure. It is usually much larger than a backhoe loader. A dumper is also designed to carry heavy loads, but these loads are usually in smaller quantities than those of a bulldozer. Backhoes, bulldozers, and dumpers are three types of earthmoving equipment that are critical to the success and efficiency of a mining or construction project.

These are some quarry, mining & construction Equipment in Perth and other places, which are quite essential and useful in these processes. Click on this link to get more information on other necessary equipment.
