Healthy Interest at Recent Vancouver Conferences
March 2005 by Leonard MelmanConsidering the frequency of mining gatherings in the USA, Canada and worldwide, many of our readers may wonder if there is sufficient new information available to make each gathering interesting and informative. In fact, they need not worry at all because rapid advances in mining technology...
While some future cobalt will come from recycling lithium batteries and other products, the coming huge need for cobalt is virtually a perfect storm of heavy demand and insufficient supply.
The process we will be using is called “blockholing,” and it is commonly used at mines and in construction projects to break up oversize material into sizes that can be easily handled.
Since the cycle of water flow is dominated by excessive and sudden “gulley washers” after downpours typical of desert country, there is a tendency to spread gold values out in the alluvial fans and not have placer gold concentrations more typical of big river deposits.
Alluvial fans are essentially dry land “deltas” which can be found in all climates. However, they are best developed in arid and semi-arid regions, where they may be many square miles in area. They are built up by outpourings of silt, sand, and gravel caused by seasonal run-off, as well as by boulders and cobbles carried by flash floods.
