We’ve no doubt all seen the old western movies of the prospector with a pan in the river searching for gold. In early America, pioneers sunk their fortunes into searching for gold this way.
In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It’s largely a matter of technology and requires much expertise and elaborate equipment.
Mining for gold today can essentially be broken down into 9 steps. Continue reading to learn more about how gold is discovered, how it’s brought out of the ground and how it’s refined to produce beautiful gold coins, bars, jewelry and other items.
Step #1 – Finding Deposits
The first step is discovering where gold deposits may be. Geologists use special ‘geology’ maps to look for promising areas to explore further. They examine physical and chemical characteristics of surface rocks to determine if any gold is in the ground beneath.
Step #2 – Analysis of Promising Areas
Once some promising areas are identified through their geological characteristics, targets for drill testing are outlined using a variety of techniques, including remote sensing, geophysics and geochemistry (…both air and ground based).
Step #3 – Drill Testing/Samples
Next, rock samples are taken through drill testing and analyzed. Geologists and mining engineers use these samples to determine if gold actually exists, the size of the deposit and the quality of gold in the ground beneath. This information is used to determine if enough gold exists under the surface to make mining worthwhile.
Step #4 – Type of mine
If it’s determined the amount and quality of deposits makes mining worthwhile, engineers will next determine the type of mine that’s needed, any physical obstacles and the impact the mine will have on the surrounding environment.
Step #5 – Building Infrastructure
Before any mining can take place, infrastructure like roads and processing facilities must be constructed. Even the simplest open-pit mines can take up to a year to construct before any mining can occur. And since many potential mines are in remote areas, entire infrastructures like roads, administrative offices, equipment storage areas and even whole towns have to be built. Much of the time, it can be up to 5 years between the times discovery is made to when actual mining takes place.
Step #6 – Mining samples and determining processing
Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique.
Step #7 – Processing (on-site)
Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing.
Step #8 – Refining (off-site)
Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out. Crude gold is melted and treated with chloride, which converts any remaining foreign metals to chloride which will then drift off the gold. The result is 99.5% pure gold, which is then cast into electrodes (…known as anodes) where it is then placed into an electrolytic cell. A current is then passed through the cell, with the end product being 99.99% pure gold.
Step #9 – Mine reclamation
After a few years, gold reserves in the mine will be exhausted. In the old days, the mine would be boarded up and abandoned. Today though, a reclamation project is done to try and return the land to its previous natural state – as much as possible anyway.
As you can see, the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot front-end investment and time. In the end though, we get these shiny coins and bars to enjoy.
Gold miners too take special care to make the impact of mining for gold as light as possible. Reclaiming land to its previous natural state is the final and perhaps most important step to ensuring the process of obtaining gold doesn’t result in permanent damage to the landscape.
The post on the 9 steps of how gold is refined, has helped me to relate the process of God’s divine will has a child of God, when one is choosen by God, he or she has to go through a process in order to accomplish the will of God and also to embrace others in knowing God. I was inspired spiritually by God in researching the steps and process gold has to go through to become the finest gold.
Thank God , was thinking the same way…God bless.
Actually, I was searching for a spiritual insight which you have defined here.
Thank you Tracy
Excellent insight. I’ll be a Miner soon and find this info so valuable. Spirituality is better explained here as well.
Need more people assist in starting a plant early next year if all goes well. Thanks
Hey Vic where are you gonna mine?
this help me so much on my project that i have given by my teacher and ithink it’s going others thank you so much
its good but I think you should add more info
Yes like right know I wanted places where gold is purified but I can’t find them
It seems that many have thought on the “gold” mentioned in the Bible and having done so, think further about the processing of it spiritually in one’s own life. The temple was covered in gold. We go through processes in our lives too so that God can clothe us in His righteousness – not our own, and it is a costly process and time-consuming but the value of it will one day be revealed – not now but when the process is completed in His time.
Thank you for the information which shows that true gold can only be found when the earthly part of it is removed!!
Great insight from the spiritual angle, I was actually researching on Gold processes in relation to spiritual growth aspect.
Thinks so much 9 steps helped in my assignment Thinks more again
i m currently discovered Gold mine and I’m soliciting capital to start mining
We are interested in gold mining and have the financial capability
to support funding for gold mining. Currently we have a gold mining project in Indonesia.
Alan
nice piece of info
Thanks so much, it helps in my assignment.
Thnx so much you really helped me with a sermon assignment as taking an unbeliever from darkness to purity
I agree. I too am writing on how God refines his people as gold is refined.
The information is much helpful, thanks.
Your post has helped me to know the journey on which God wants me to embark even though I don’t understand God. Thank you. God bless you.
This really helped with my school work awesome:)
thx bruh
This really helped with my school work. Thank You so much! =3
Thx my bro Bethany
Thanks, this helped a lot with my assignment and school work in science so yeah thanks for the good post
Thanks, this helped a lot with my assignment so yeah good post
Thanks, this really helped with my assessment!!!
You helped me so much with my school work thank you very much!!!
Thank you this is sooooooo helpful!!!!!!! 🙂
My pastor was teaching about the process of becoming pure gold, thank you for your explaining the process. It makes my life in Christ a lot easier to endure.
What did the pastor say about the process? The above information
is quite involved
Yeah! This just got me answers for my assignment!!! Thanksss
LUV DIS POST!!!!!! THX 4 DA INFO;)
thank you
thanks i love this post.
I cannot thank you enough for the blog post.
