The MBMM Gold Mine - Mt Baker Mining and Metals
The mine was discovered in 1897 and was a producing mine until World War II. The old-timers hauled machinery and supplies via horse trail over a treacherous seven mile long trail to reach the mine. Initially working with single-jack bits and black powder, they produced the gold-rich ore that was processed on-site.

recovery underestimated, and that the decision to go with milling may have been incorrect. Differential Recovery Is Not Sufficient To Justify Added Investment A recent review (Kappes, 1998) concluded that for a "typical" Nevada-type ore body with ore grade of 3.0 grams gold/tonne (0.088 oz/ton), the mill recovery would have to be 21% higher than
Bond Work Index - an overview | ScienceDirect Topics
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly ...
