    True Cost To Mine Gold - Companies Under Pressure

    So, there's a point where you "throw in the towel". - Geowizard
  2. Having gone through the process of bringing a placer gold mine into production and profitability, I thought it would be good to share some of the experience with others that might be interested in doing the same thing. - Geowizard
  3. Which mines are your favorites? - Geowizard

    Low Level Heating Ideas For Mine Buildings

    Waste oil; A byproduct of mining is waste oil, contaminated fuel oil and unleaded fuel. Every time I prepare for a fuel delivery... I dump empty 55 gallon barrels into a 5 gallon bucket and funnel the "P" into a waste barrel. This separates sediments, insects, and other forms of fuel contamination from clean incoming fuel. The "P" barrel provides a perpetual source of heating oil for a simple 1/4 cut-off 55 gallon barrel. The stove is simple, cheap, portable, easy to clean. Oil and grease rags are usually discarded and burned with trash. I separate burnable trash and burn it in the Hobo burner. Using ote's suggestion of "mass heat storage" is an excellent idea. Most old mines have cast iron relics of all sorts and descriptions that can be heated by the heater and will store heat and provide slow release for many hours. - Geowizard

    Sulfides

    Fireware; Check out fireware at prospecting shops like A&B Prospecting or Legend - What do you suppose customers use a #16 Silica Carbide Crucible for? It will hold 68 pounds of red brass. - Geowizard

    Low Level Heating Ideas For Mine Buildings

    Hobo Heater; Multi-fuel - oil burners are the heater of choice. Issues that can be problems are soot build up and level of burn needed to prevent soot build up. A low level burn will not produce sufficient heat to force soot up a chimney. Fuel is readily available, easy to transport and easy to store in remote locations. At my remote campsite 2 miles from the cabin at Ophir, I use a simple "Hobo heater". A Hobo heater can be anything from a #2 coffee can to a 55 gallon barrel with the end cut off. Works on the same principle as a candle. You have discarded grease rags immersed in a small amount of oil. The rags work like a wick. If wood is added, the charcoal will provide similar wick action. The purpose of the wick is to produce a slow burn and not heat the oil to combustion - the wick burns slow and almost indefinitely. This option requires adequate ventilation. Having lived in Fairbanks, I know mid-winter temperatures actually suck the heat out the door when you open it. For fall temperatures to late fall, with ventillation, the Hobo heater works great! - Geowizard

    Gold Refining

    Digression of discussion; The subject of gold refining is digressing into a debate over whether a less strong acid (lemon juice) will dilute a stronger acid. There is no point in trying to discuss a subject when the administrator intervenes for the sole purpose of argument. - Geowizard

    True Cost To Mine Gold - Companies Under Pressure

    If you agree with Chris; When the true cost of mining is greater than the return - throw in the towel! - Geowizard

    Gold From Old Tailing Pile

    auburncaligold, Welcome to the ICMJ Forum. The old timers certainly left gold in their tailings. My personal experience has been from running tailings in Alaska. Low grade tailings that run $10 a yard through a 50 yard per hour plant for 10 hours can put $5,000 in your pocket! Visit http://www.ophir-alaska.com - Geowizard

    Robert, Yes, it IS a matter of training people to do the right thing. Operating manuals even come with a page or two on filling holes. - Geowizard

    The Gravity Method

    The Gravity Method; Prospectors use many different methods to find gold and other precious metals. One of those methods is a geophysical method referred to as the "Gravity Method". - Geowizard

    The Gravity Method

    Various instruments have been developed to measure the force of gravity. There are applications in prospecting for deposits of minerals including gold! - Geowizard
