History of Gold Mining

history-of-mining-goldWe are all interested in finding, mining, and panning for gold.  This has been going on for a long time, especially in the United States since the mid-1800′s during the gold rush in California, Georgia, and Tennessee.  There is a current, smaller scale gold rush going on since the television networks have started syndicating shows about the topic, such as Gold Rush: Alaska, Gold Fever, and Prospecting America.  But what about a long, long time ago when the first people thought, “Hey, we all like these precious metals and stones from out of the ground.  I’m going to get rich by finding my own!”  Let us discuss the history of gold mining deeper…

Nobody really knows when people first began trying to find gold, but we do have some dates on old artifacts created out of gold.  These were discovered in Bulgaria at the Varna Necropolis.  The gold artifacts were found in graves which have been dated to some time around 4500 BCE.  This tells us that gold prospecting and gold mining is in face at least 6000 years old if not closer to 7000 years.

Hard Rock Mining

hard-rock-miningHard rock mining is an underground mining method that is used to mine extremely hard materials, such as those containing ores such as the valuable metals we are going after, specifically gold.  The excavation of these hard golds, silvers, diamonds, and other minerals requires a few things that we will be discussing and we will also mention the methods and techniques applied, as they are very different from the placer mining we have been discussing at length.  Let us explore.

The first obvious thing you need to work on underground hard rock mining is underground access.  There are ways to get this done.  There can be what is called a decline, which involves a tunnel with either spirals downward or slowly heads towards the target at a slight angle.
These are started into a rock side or the side of an already dug cave.  There will often be load-bearing supports brought in to help keep everyone safe.  Another method is just a mine shaft, which is a vertical well-type hole dug next to the body of rock you will be working on.  You can also haul the ore out this way as well with buckets.  Finally, there are adits, which are horizontal caves or excavations dug level and to the side of ore bodies where you don’t need any kind of ramp or spiral decline.

Gold Mining Equipment

gold-mining-equipmentWe’ve talked about a whole bunch of different methods of mining gold up to this point and have mentioned the various types of machinery involved.  But that’s not the whole story.  There are lots of other accessories you will want if you are going to maximize your efficiency and safety when mining gold.  There’s a lot of gold mining equipment to consider, so let’s get started.

For big time mining jobs, we are obviously going to need large drills, bucket lifts, dump trucks, bulldozers, and more.  This is for the large companies digging caves and mines and shafts.  I’m not really going to focus on that because it’s really outside of the scope of what we as individuals will probably be doing.  Even a small team can’t get the funds together for all of that.
