Large 7.5 ounce California gold nugget

.

Prospecting is a technical subject and the more you know the more gold you will find. Whether you are a new prospector or an old hand, there is always something worthwhile to learn. I have a degree in Mining Engineering from the Mackey School of mines, and I write a monthly series of articles for the ICMJ Mining Journal covering various aspects of prospecting for gold, collecting gems and minerals as well as other similar activities.  I've put together these pages to share some information with my friends on the internet. Each topic below has a wealth of information on prospecting for gold, so make a selection and take a look...... 8 ounces of large Alaska gold nuggets

Getting Your Fine Gold Out of Those Black Sands

Nearly every placer gold deposit has at least some of it: black sand. It collects in our concentrates and gets in the way of recovering our fine gold. Some prospectors worry about getting every speck of gold and save it in buckets until they have accumulated tons of it – so what is the best way to extract all the gold that is reasonable to get? Take a look at this article to see.

Sulfides, Selenides and Tellurides: Refractory Ores

The early day miners feared it, and it happened a lot more often than they would have liked: the easily worked rich surface ores they discovered on the surface gave way as they mined downward, to a vein full of sulfides, base metals and other nasty, rebellious and refractory ores. So what are these minerals?

The Science of Rocks: The Common Rock Types

Prospectors need to know about common rocks. Here is a set of pages that give the details about what makes a rock basalt or granite or limestone. There a a number of different types of rocks, but these are the common ones with a special emphasis on the types of metal ores that can be found in them.

 

Assaying to Find the Precious Metals in Your Ore

Even wonder about the gold and silver content of an ore?   The goal of assaying and testing materials is to determine their metals content. In order to have an accurate idea of how valuable an ore is it must be analyzed. Here is some information on how it is done, and how you can do a quick and dirty "free gold" assay for yourself.

Gold is valuable, so how do you convert it to money? There are a lot of ways, but its important to understand the process and don’t let yourself get ripped off.  There are loads of options, including refiners, collectors who buy fine pieces, ebay, tourist areas, and even cutting up specimens as gold-quartz gemstones. There is an entire art of using HF, a dangerous acid which is used to enhance gold specimens. We will take a look at getting the most for your gold here.

Finding and Mining Hard Rock Gold Deposits

Learn about finding gold deposits by tracing, also known as loaming. Here is also information on drilling, blasting and stopeing - the basics of hard rock mining. I have also included information about small scale crushing and processing of free gold ores using equipment like a jaw crusher, ball mill and shaker table.
