About the Author:I am an assayer with eighteen years experience in the Nevada gold mining industry. Most (but not all) of the ore I currently encounter is a type called "carbonaceous"; ore of this type requires a "roaster" type milling operation to recover the gold. (The first image, below, shows views of underground miners alternating with a roaster mill used to extract gold from carbonaceous ore.) Traditional fire assay is the primary method used for assaying these ores, but a wide variety of other analytical methods are necessary to provide data for developing and operating a mine in a safe, environmentally friendly, and economical manner. (The second image, below, shows a step in the fire assay process.) All of the work leads to a simple product: gold bullion (last image, below). |

This site was designed as part of a college course; the original project explored the web as a tool for teaching work-related issues. Current content focuses on assaying, but it also includes family material. (Easy to skip; these links are farther down the button bar.) |
| If you have suggestions for new links or additional
content within the design scope of assaying and family activity, use the
link in the title bar to send me a note. I'm always hoping to learn
(and pass on) something new.

| Viewing note: This assayer
site is best viewed in Netscape
4.0 or later (MS Explorer 4.0 or later works almost as well); some
features cannot be accessed or viewed in earlier browser versions.
View quality improves with monitor settings adjusted for higher resolution,
more colors and small font, if feasible. Many features (quizzes,
ore models, etc.) will not work without a JAVA enabled browser. Alternate
text explanations of pictures and diagrams are only visible if this viewing
feature is activated in your browser setup.
All pages in this site are designed to display through a main frameset. If you have a smaller monitor that makes frame details hard to view, right click on any display and select "Open Frame in New Window". This will open the current frame to full screen size. If you are using a browser that does not have a frame-breaker function, use the "without frames" link found on the bottom right of most pages. |
