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.

What indian lands were invaded by miners?

Indian lands in the United States, such as the Black Hills in South Dakota, were invaded by miners during the Gold Rush era as they sought valuable resources like gold. This invasion often led to tension and conflict between indigenous communities and miners, resulting in the displacement and mistreatment of Native American tribes.

What was the only African empire to include a Saharan salt mine?

What were the first methods of placer mining used?

Placer mining (pronounced plasser, BTW) is mining for gold that is free of the rock. This is usually in the form of gold dust and fine nuggets. The simplest means, and the first used, was panning for gold in the rivers. You can also used a sluice box, where sand is shoveled into a trough with water running through it. Running water carries away lighter materials, and leaves the heavy gold in grooves on the bottom of the sluicebox.

Did every mine have a shaft?

No, not every mine had a shaft. Some mines used adits, which are horizontal tunnels dug into the side of a hill or mountain to access the mineral deposits underground. Adits were particularly common in hilly or mountainous regions where it was easier to dig horizontally than vertically.

How many mines were there in the cannock area?

The decline of coal mining has been accelerated by factors such as coal's environmental impact and the increasing use of renewable energy sources.

What replaced the placer mining?

Placer mining was largely replaced by hydraulic mining and hard rock mining methods. Hydraulic mining used high-pressure water jets to extract minerals, while hard rock mining involved digging tunnels and shafts to access mineral deposits underground. These methods were more efficient and able to extract minerals from deeper beneath the surface.

When was mining invented?

Mining dates back to ancient times, with evidence of mining activities as early as the Stone Age. The advent of metal tools and weapons in the Bronze Age further accelerated the development of mining techniques. By the industrial revolution in the 18th century, mining had become a significant industry worldwide.

When was the first mine shaft made?

Possibly before we had writing to keep records. Man has been mining and using metals since right after the Stone Age. Bronze is a metal, and had to be dug out of the ground as its component metals.

When did copper mining start?

Copper mining dates back over 10,000 years to ancient civilizations such as the Mesopotamians and Egyptians. The first evidence of organized copper mining comes from the early Bronze Age around 4500 BCE in regions like Turkey and Serbia.

Why did the inca's go mining?

When was mining discovered?

Mining has been done for thousands of years. Ancient Egypt mined and so did other cultures. The oldest salt mine in the world is in Poland and has been in use for thousand of years.

The so called bronze age began approximately 5000 -5500 years ago, it followed the Neolithic era during which stones and flints were used but no metals. In some parts of the world copper was mined and smelted after the Neolithic period and prior to the bronze age. Copper is a relatively soft metal and it was discovered that by adding tin to it it became stronger and this alloy is called bronze. It still used today especially to make fine sculpture.

Why can't you reclaim an open-pit mine?

An open-pit mine can be reclaimed. There are some serious issues to be dealt with, and some big bucks can be spent on them, but it can be done. And in many (if not most) instances, some form of reclamation is mandated by the governments of the states (or countries) where open-pit mines are operated.

In open-pit mining, the mining is essentially done by digging a big hole in the ground. Any overburden is set aside, and the material sought is removed and transported away. Overburden (material that is "on top" of ore) or other dirt and earth can be used to cover abandoned mines. The large pit remains, but can be "landscaped" to restore the "look" and the "natural" earthen cover that was in place before the mining began.

Once proper covering and shaping are done and the "surface" of the land is restored, about all a company has to do is deal with water runoff or groundwater penetration issues and they can walk away. There are issues with tailings and the other "left-overs" from any processing of mined material, and these are generally sorted out by geologists and geochemists. As long as any chemical treatments of materials is conducted properly, the tailings and other by-products can be covered over with "natural" material to complete the restoration.

None of the issues associated with recovering (reclaiming) an open-pit mine are easy to address. Additionally, anything we do or demand be done comes with a price tag. But with some "signed agreements" in place and a bit of oversight by bright, reasonable people who can direct the mine operator to "do right" before closing a mine down, a "good" result can be obtained. A number of open-pit operations have been closed down around the world after exhausting rich ore or material bodies, and we've seen a "clean" environmental impact report following those mine closings and remedial activities.
