Small Mining Operations
Dredging The Outside Bend
July 2011 by Jim Foley
This stringer was where it was not supposed to be, and it contained nuggets that were not supposed to be there.Critical Minerals: Titanium
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
Small-Scale Hard Rock Mining With Water Recycling
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.
The Underground Mining Adventure Continues
Our group of independent miners have been busy crafting a uniquely designed ladder/ore cart track from the bottom of an 85-foot mine shaft in a historical hard rock mine.
Northwestern Alaska Mineral Resources
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
Why Haven't They Mined This Claim?
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Small-Scale Concentrating and Recovery Methods
The first step in my recovery process after milling the ore to the desired size is to table it. On this particular ore, I get good results milling it to minus 100 mesh.
Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
