In todays article, we will give you a short introduction on how rubies are mined and the process involved.

The main methods of mining rubies are placer, underground mining and hydraulic mining; the method depends on how deep into the earth the rubies are situated. There are other methods which we will also briefly touch upon.

Placer Method of Mining

The placer method is also known as river panning and involves collecting the gemstones whilst washing away gravel from a river. creek or stream; an obvious pre-requisite of this is identifying the gravel which could possibly contain the rubies.

A large pan is filled with water and then it is shaken back and forth to ensure the heavy materials fall to the bottom of the pan; this is repeated until there is a small amount of concentrate left in the pan. Then this concentrate is moved to a smaller pan to see if there are any gems.

Hydraulic Mining

In hydraulic mining, very powerful jets of water are used to loosen the gems from the rocks. The water splits the rocks and washes large pieces downhill; this causes the gems to be separated. Due to its harmful effects on the natural environment, this type of mining is not used now.

Mountaintop Removal Mining

This method entails cleaning the mountaintop at the ground level by cutting down trees and shrubs. Dynamite is then used to blast the top of the mountain; the resulting large rocks are then scoured for the gemstones.

Underground Mining

This method of mining is used as an alternative to surface mining, which is often not possible. This is the most common way of finding gemstones, and involves miners digging underground until they find gemstones.

The main forms of underground mining are:

Borehole Mining

Holes are drilled very deep inside the land using very large bore drills. Then a plastic tube is passed through the hole, water is then pushed through this tube at very high speeds. This water breaks the rocks and forms muddy slurry, which is stored in tankers. The water is then separated from the slurry to leave gemstones.

Drift Mining

Drift mining is performed on the mountains and entails first identifying rocks which are below the side of the mountain. The opening s created are called tunnels, and the gemstones are derived from the materials that come through the tunnels down from the hills.

Shaft Mining

Vertical tunnels called shafts are created below the mountain when shaft mining is used. Miners move up and down one of the shafts and another shaft is used for bringing the material from below the ground. More tunnels are made for blasting the rocks and the gems are found from amongst the rocks.

Summary

In most of the mining methods we have discussed, rocks are broken down into small or medium chunks using explosives such as dynamite. These rocks are then processed to extract the gemstones. Once you have the raw gemstone, it can be cleaned, cut and polished to produce the finished article.

When it comes to considering your funeral someday, many already know exactly what they want in terms of a burial. There are so many options available to those who can stomach it. One idea that is coming back into popularity from ancient rituals is the idea of Mausoleum Services, or virtually being mummified in an above-ground tomb. Here are a few reasons to consider choosing a mausoleum.

It is a Type of Preservation

If you are interested in a unique way to be buried, this is certainly for you. By being buried in an encapsulated above-ground casket, the deterioration process cannot really take place. In turn, this actually begins a type of mummification, the preservation process on your body. Many people go for this option for the possibility of being used in scientific experiments in the future.

It Can Be Cheaper

Mausoleum Services are sometimes complicated, but, for the most part, can sometimes be cheaper. Because the casket does not have to be sealed in the same way that an underground casket does, it can essentially knock a few dollars off of your burial fee. Depending on the time of year and the circumstances, you can be sure to get a fairly inexpensive burial with a mausoleum.

It Does Not Need Maintenance

With a gravesite underground, your loved ones consistently have to maintain your plot. Weeds and things may grow and even the tombstone is not always weather-proof. With a mausoleum, you eliminate the maintenance work for your loved ones and put yourself in a grave that needs none at all. This can keep them from having to go back regularly, reliving the pain of losing you once again.

As you can see, there are many benefits to this unique form of burial. Not only will you stand out from everyone else, but it can also be cheaper and does not require as much maintenance to your gravesite. If you are planning your funeral and are looking for a cheap and unique way to be buried, consider a mausoleum as your first option.
