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.

Gold Mines

gold-minesMost of what we will talk about has to do with placer deposits for mining gold, and most of the methods of gold extraction will be placer methods, however it is worth mentioning that there are other types of locations to recover gold from, but they aren’t usually places that individuals and small groups will have access to.  One of those types of places are gold mines.  Gold mines are nothing like the placer deposits that form at the bases of waterfalls and around river and stream bends.

Gold mines are man made caves that are dug out or dug down into the earth in an attempt to find gold veins that are hidden from view.  There are large pieces of gold all throughout certain portions of land and embedded in giant rocks.  So looking in streams is not always the answer.  If you have the large mining equipment to bust apart the rocks and filter them down, perhaps using sluices, cradles, and trommels you will be in good shape.  But this is usually limited to larger companies who have the money to lease, rent, or buy these enormous pieces of machinery needed.

Gold Extraction

gold-extractionGold extraction, sometimes known as gold recovery, is the process of extracting the gold form the surrounding ores.  This is can include any combination of certain procedures such as comminution, pyrometallurgical processes, mineral processing, and hydrometallurgical processing.

What these mean, in the same order, is crushing and grinding to reduce the size of the rocks, using heat and fire to remove the metals, different ways of crushing again, and using water to extract the gold.

Gold Dredging

gold-dredgingAs we continue to dig deeper (no pun intended!) into gold mining techniques, we will look another method which is calledgold dredging.  This is another type of placer mining, which is extracting gold from the black sand that collects in placer deposits.  The previous method of placer mining we discussed was gold panning, however gold dredging is more advanced and more efficient.  So what the heck is this thing?  Is it big or small?  Does it require engines and laborers or is it automated?  Let’s figure this thing out!

Gold Deposits

gold-depositsWhen the phrase “gold deposits” comes up, it is in reference to places where there is a boatload of gold.  Now, this refers to a lot of different types of areas, such as gold mines, gold claims, gold placer deposits, and even within the placer deposit category we have residual deposits, alluvial deposits, glory holes, and more.

A gold mine is a man made excavation created to gain access to a gold vein, which is a location where much gold has been formed and is ripe for the recovery.  It takes large machinery and a lot of money to purchase land to be able to construct a gold mine, but if you can get ahold of these types of gold deposits, you will be rich without question.  Other types of gold deposits are the gold claims, which are essentially any mixture of the other types of gold deposits, and someone has just laid claim to the area as the one who gets to mine it first.
