Putting Together A Small Free Gold Mill
May 2018 by Chris Ralph
Most small-scale miners want to know how they can set up a system much more cheaply. The difficulty is in the balance of putting together a decent small-scale system at a reasonable cost.
Setting up a gravity dredge
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
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.
While mapping, I also found rock chips in the soil that were characteristic of the same wall rock alteration that occurs adjacent to the known lodes in the greenstone belt.
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
Augers can be used effectively for placer exploration with certain limitations.
