Put sample concentrates rocks that have been smoothed into phirex which contains Aqua Regia and hea

Okay guys, we're going on a small cruise to the world titration. What is a "titration"? Well, this is the method to find something that we want to know. Stages graded stages so that we can know when a particular event occurs.
Usually that is done is to gradually acqua minerale increase the sound until we could hear clearly before finally drawn a conclusion about the condition of our hearing. A person with normal hearing can detect a frequency of about 20 to 20,000 cycles / detik.Seiring with age usually we start to lose our high frequency sharpness.
Let's get on with it. First, what do we mean by the word "Test"? This means determining what is in the sample (the sample) in everything we do. Gold should not. We can test other materials such as silver, copper, sulfur, water, acqua minerale chewing gum, anything. We must understand that there are two basic classes test. Qualitative and quantitative basis.
Qualitative tell us what is in the sample. If someone brings a quartz rock sample and said, "I want to know what is in it". We take it to a lab and run test according to the procedures and issued a report saying "Sir, you have quartz, sulfide, palladium, silver, copper, and gold". It is a qualitative test.
Of course, our client who is a prospector (Gold Finder) immediately asked "how much gold"? The answer is "who knows". Or "to pay Rp. 300.000, - you will get it. Then we take it to a lab and run test according to the procedures and issued a report that said: "No father in the rock sample contains 13 PPM Gold" that quantitative answers.
Now I'm not saying that everyone should start buying equipment to install its own test laboratory. I just thought that you might want to know what happens when you bring a sample to the lab test and what it does.
I'll put some R & D methods that you can do on the field to help you determine whether the site (mine) you have better than anyone else. Therefore, you have to read everything to obtain this information, it is very necessary. You do not want to miss it, right?
There are several different ways of testing for precious metals. Some of these are relatively new such as "ion probe analysis". Take an example (sample) (must be in one piece) with minimal metal content to the lab and they put it in the Scanning Electron Microscope and press the button. ZAP! Come out to plot graphs acqua minerale of all the precious metals contained in the sample and the amount of each. The other is a method where you take a soil sample and put it into a small device called Fluorescence Spectrometer. This will give you an instant readout of the amount of gold in your sample. We are not going into the details of this hi-tech methods. We will concentrate on methods that are available around us like a test with "Aqua Regia" and "fire test" is more simple and general. If no longer acqua minerale useful acqua minerale method we will enter in the future.
Aqua Regia and then pour into phirex contains distilled water. Composition of distilled water with Aqua Regia is 1: 1, so as to avoid strong odors but enough for aqua regia to react.
Put sample concentrates rocks that have been smoothed into phirex which contains Aqua Regia and heat with temperatures acqua minerale between 85 to 90 degrees Celsius acqua minerale for 30 minutes in the embers of a fire or stove. And observe the reaction.
After the reaction is complete wait until cold aqua regia solution and precipitate. And then filtered using a tea strainer on top of the filter is added with a cloth napkin. So it will separate between sediment and aqua regia solution.
To test the gold content in rock samples, take little or filtering the resulting solution drops onto a tissue or cloth, acqua minerale then grab and dropped into a little gold detector solution upon it.
Tungggulah tissue was dried, then observed when the droplet changes color to purple means we rock samples containing gold ore, if the color does not change means it does not contain gold ore.
In this method a weighed amount of soil samples covered with about 2-3 volumes of Aqua Regia and heated. The samples were cooled and then filtered and washed residual solids 3 times with dilute hydrochloric acid. All fluids were collected and evaporated by heating gently until only a very small amount remaining. Then, hydrochloric acid is added and the evaporation repeated. Chloride leaching was repeated 3 times to ensure that all the nitrate was lost. Now you have the value-n
