XRF Working Principle
Here is a great little educational video on an XRF Working Principle.
Fundamental XRF Principle of Operation
This video best details and explains the fundamentals of an XRF’s Principle of Operation. A prepared sample specimen is excited by the radiation of an X-Ray. This causes a electrons from the inner electron shells to get knocked-off. Electrons from outer electron shells drop-in to fill the resultant voids emitting a fluorescence radiation characteristic in its energy distribution for a particular element/material. This fluorescence
Difference Between XRF and XRD
In summary, the difference between XRF and XRD is simple: XRF analyzes for Chemistry while XRD determines the mineralogy. XRD identifies and measures the presence and amounts of minerals and their species in the sample, as well as identify phases. XRF will produces and assay by giving information on the chemical composition of your sample without indicating what phases they are
Sub-A Flotation Cells
The Sub-A Flotation cells technology has been around for a long time since the Denver Equipment Company first developed it in 1968 after inventing the flotation machine of 1940 and changed the mineral processing industry. The SUB-A float machines used in the mineral, chemical, environmental, and industrial applications requiring the efficient dispersion of fine air or gas bubbles in slurries or liquids. The units are designed
Compare Gold Analysis Techniques – Methods
Metal’s prices volatility causes various gold rushes or exploration push creating the need XRF instruments for quickly obtain metal/gold assays. From pawn brokers to jewels and precious metals recyclers. Be sure to be armed with a XRF instruments to not be fooled. XRF instruments are fast, easy to use and precise. Below is a comparative table for gold assay methods, accuracy and price. Here a
XRF Analysis Elements Capabilities
Depending on the XRF Model and capability you have, here is a list of elements most with assay or analyze for.
Olympus DELTA XRF Analyzer Price
I asked around for you on the topic of NEW Olympus DELTA XRF Analyzer Prices. Here is a quick price comparative table for different new XRF or x-ray fluorescence analyzer price. A good cheap, as in low cost Laboratory Pellet Press is great to have. Around $18,000 US Alloys Only Starts at $26,000 US Mining Mode Only Around $36,000 US
Gold Jig DIY Plans Hand Operated
For for Coarse Gold Recovery (>2mm), here is an easy to build hand-operated mineral jig. This jig can be used for batch ‘jigging out’ gold from oversize (>10 mesh) from pre-sluicing or panning rejects as occasionally there will be coarse nuggets present in the oversize rock and this can-be-homemade jig works as a simple hand operated device especially developed to recover
Putting a Ball or SAG Mill on Care and Maintenance
The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need to lift a car higher than a mill. All you need to do is jack
Titration of Cyanide Solutions Containing Dissolved Copper
When silver nitrate is added to sodium cuprocyanide of the composition Na2Cu(CN)3, an appreciable amount must be added before a precipitate comes down. The reactions are believed to be as follows: 2 Na2Cu(CN)3 + AgNO2 = 2 NaCu(CN)2 + NaAg(CN)2 + NaNO3 On further addition of silver nitrate, a precipitate of CuCN begins to come down: 2 NaCu(CN)2 + AgNO3

Dredging for Gold
The first thing that probably comes to mind when most people think of searching for gold is panning for gold from streams. After that, they would most likely name mining gold from solid rock, such as from a large open pit or from tunnels blasted along lode-bearing quartz veins. Who could blame them? Exciting stories of gold prospectors discovering the
Gold Plating Machine
If you want to rehabilitate old gold plated jewelry, preserve a memory, or create a keepsake from a natural object, a gold plating machine is an excellent option. At about the cost of a sewing machine, these simple and affordable devices can pay for themselves over time just as easily as other household appliances, and it’s always a delight

Here are 2 very educative and important Must-Watch Videos that should form the core of any Metallurgist/Engineer Training Program. Depicts Experts and Confidence (over). Incompetence annoys, overconfidence terrifies.
Elements Associated with Gold
On a Periodic Table, elements often found to associate with gold have been group/classified. Elements Universally Associated with Gold Elements Typical in Minerals Commonly Associated with Gold Elements Concentrated in Gold Bearing Mineral Associations of Individual Orebodies Elements Characteristic of Gold Only Ores Elements with Traces Commonly found in Gold and its Compounds. This does not tell us how are gold
How to Value a Gold Deposit
How do you measure the value of gold a gold deposit still in the ground in terms of a company that is mining or in production exploration stage? The starting premise is how we value advanced explorers and developers to target companies that are undervalued with respect to their peers and evaluate how viable they’re as stakeholders. We use peer
Calculate Top Ball Size of Grinding Media -FRED C. BOND Equation & Method
Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

Cominco Polaris Mine
Polaris was such a nice workplace. Maybe my memories of it are skewed a bit be the fact it was my very first really mining job, but in any case, I only remember a very nice spirit up there. I also remember the Chili Peppers and the Polar Beach Party. https://www.lostmines.net/polaris-mine.html
SABC Grinding Circuit Operation & Optimization
When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted in the circuit being converted to single-stage
