Principles of Designing Your Mill Production System, Part I: Starting Up
January 2021 by Keith Bowen
One of the issues that prospectors run into when working to upscale from micro-scale hard rock testing to a greater production output, is that they often confuse individual devices or machines with systems.
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.
For this article, I am focusing on industrial production plants that can handle 10 cubic yards per hour or more and would be fed by a loader or other heavy equipment...
Q: How do I improve my small-scale mining operation’s gold production?
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
Everyone has a bucket list, and one of my items has always been to dredge and dive in a major river, Oregon’s Rogue, with the opportunity to find some chunky gold.
Sampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.
I am going to suggest dozens of ways you can increase suction power, dredge to greater depths, and improve recovery methods in your sluice box.
