When asked to lecture at Bendigo on the geological factors that determine the depths of ore deposits, I hesitated for a little before agreeing to
For a number of years I have, at odd times, tried to perfect a method of assay sufficiently delicate to find and estimate very small/trace quantities
The building of reverberatory furnaces (Fortschaufelungsofen) where ordinary brick, fire-brick and iron are comparatively cheap, is quite a different matter from the building of such
I was manager of a mining enterprise where the ores were composed principally of iron pyrites (much decomposed), in a quartz matrix, with native gold in
The study of an entirely new series of alloys may be undertaken from a desire to obtain knowledge applicable to the perfection of industrial alloys,
The engineer has often to penetrate difficult or unknown regions. Mineral, irrigation, boundary and railway problems frequently necessitate journeys through, or long residence in, localities
The limit of pressure to which an underground dam may with safety be subjected, is a question that—as far as the writer knows—has not received
It has been more especially in these large low grade ore bodies, that modern methods have been beneficial; for small lodes must be rich to
In the Engineering and Mining Journal there appeared an article by Fred T. Greene, describing a method of measuring stopes by the use of strings,
I have chosen this subject in view of the fact that, while there are many and ample opportunities of getting reliable assays made, there are but
