Mineral Recovery Methods
There are 5 main mineral recovery methods and we’ll talk a little about each of them in this article.
By the way, this is the webmaster writing. I’m good at web things (only), while Ian is the expert when it comes to gold recovery. But I just watched the free DVD about the gold wave table so I can tell you a little of what I have learned.
The DVD was made by Mike and Nancy Glenn of Action Mining Services in the USA. Their company makes these remarkable machines. More on that later…
Mineral Recovery Methods
1. Leaching. This uses chemicals, and more technical know-how is required than you need to use a gold wave table. Chemical leaching is also the most expensive mineral recovery method. Mike’s main focus is on gold recovery but the machines work for any mineral which is heavier.
2. Amalgamation. The idea here is that you first amalgamate the gold with mercury and then you separate it. But Mike explained that this is not easy. “Your mercury has to be clean and your gold has to be clean. Then they have to come into contact.” Like #1, this process is also technically intensive then it requires another operation to get the gold out of the mercury. And mercury fumes are poisonous.
3. Flotation is also technically intensive.
4. As he worked his way down the list, next came mechanical separation which is what the Micron Mill Wave Table does. It’s a wet gravity separator that separates any heavy mineral according to its SG (specific gravity). This doesn’t use chemicals. Just water and the oscillating wave table. It’s quite neat to see it at work on the DVD.
5. Finally sluices, the traditional method of gold recovery, are the easiest. The problem with using a gold sluice is that it misses the fine gold… the microscopic gold. The Wave Table machine is able to recover this micron-fine material.
The DVD presentation showed a bucket of dirt being poured into the system at one end, and out comes a concentrate containing the gold particles.

My father has a home in the Black Hills of South Dakota. One of his hobbies is mining, in the rivers around the homestake gold mines. I will shoot him over the information on the DVD. Thanks for the post.
Nice to know about the different minerals recovery methods, actually I know very less about them and this post is quite good on how Gold is separated and converted into a pure gold which we see.
There seems to be some very tedious processes involved in Gold Mining but I don\\\’t find any links to DVDs on that link?
thanks! i was researching this for a project but it was difficult to find what i was lookinf for. you explain it great. I remember panning for gold outside of sacramento california. great fun.
I would be interested in information on both test model as well as small production model of your gold recovery device. BOB Delaney.
then why do they use cyanides in gold mining industry ? I’ve heard that this industry destroys everything in its way, land, homes, etc, bratari argint
Could you post a link to this free DVD you’ve seen ?
Flotation is the most extensively used method worldwide to separate minerals from mineral resources. Optimizing the recovery of valuable minerals from both fine and coarse particles in flotation is one of the most significant challenges facing the mining industry.
A method for the recovery of mineral resources, such as metallic minerals, petroleum, etc., from solid materials, such as subsurface earth formations, including; partially burning a hydrogen-containing fuel in the presence of an oxidizing agent under conditions to produce partial oxidation products, such as alcohols, hydrogen peroxide, aldehydes, ketones, etc., terminating the burning to prevent decomposition of the partial oxidation products and contacting the solid materials with the partial oxidation products and contacting the solid materials with the partial oxidation products and an alkaline or acidic material.
It’s a very technical process. Most people can’t tell the minerals apart from one another.
