    Metal Detector Theory

    I have watched inexperienced prospectors swinging a metal detector too high above the ground. Those that are experienced would wonder why someone would not keep the coil close to the ground. This is one reason why understanding theory is important. - Geowizard

    Metal Detector Theory

    RSJ, I agree. Prospecting is a challenge without turning it into a science project. - Geowizard

    Rick, The SDC 2300 uses MPF (pulse) technology as well as the GPZ 7000 which uses ZVT (Bipolar pulse) technology. Pulse technology is good for "Horseshoes and Hand Grenades" as illustrated on the Minelab website. Best way to test the response is to check them out at a dealer if you have a chance! Verify the gold content by crushing, screening and panning. Then get the gold assayed or refined. Good luck! - Geowizard

    Metal Detector Theory

    Theory is after-all speculation. Metal detector theory is no exception. There are those that consider mathematics to be theoretical. The theory of metal detection is based on mathematic models (theory) of an electromagnetic response. So, we are left to speculate on the probability of what the application is that Ricky is willing to provide information about. Any discussion on metal detector operation is theoretical. Probability of what the application is - doesn't matter. - Geowizard

    Two BS detectors are better than one. - Geowizard

    Buried Treasure!

    How do you separate junk from gold? Metal detection is actually pretty simple. Almost anyone with a metal detector can detect a beer can. Separating trash from gold is the "finesse" that separates winners from losers! - Geowizard

    Extremely Fine Gold Recovery

    The chemicals are used for recovery - not refining. Mercury is used for recovery - not refining. Flotation also uses chemicals for recovery - not refining. Recovery of gold is a process of upgrading the gold to a pure gold end point. Since raw gold is recovered as an impure product, refining becomes part of the recovery process. Splitting hairs doesn't contribute much to the discussion. - Geowizard

    Buried Treasure!

    The combination of the "World-Wide-Web" and Technology take prospecting for buried treasure to another level. - Geowizard
  11. With reference to "buyers"; Developing a mineral resource takes time. You can chase the market or build the knowledge of a deposit, offer an investment opportunity and "wait". - Geowizard
  12. Peter, As with prospecting of any kind, we prospectors understand the importance of looking for and recognizing valuable minerals and metals. The process of discovery is challenging and very important. You are asking an honest question. Your question represents the second phase of prospecting. Be careful listening to "nay-sayers" that distract from your efforts. Keep up the great work! - Geowizard

    Metal Detector Theory

    All metal detectors operate on the same theory. Since Ricky probably works in the business and has signed non-disclosure agreements with his employer, he should not and probably will not disclose details pertaining to the detectors his company sells. Personally, I do not think it is ethical to push others to divulge insider knowledge. Discussion of relevant theory can help prospectors to understand why metal detectors have limitations and how to properly operate a metal detector. - Geowizard

    Rick, I can believe it. PI detectors are great for nuggets and relic hunting. Your PI detector would easily find a horseshoe or mule shoe. Disseminated gold and sulfides represent difficult targets and are more difficult to detect in mineralized soil. The only way to know is to crush, screen and pan the rock. Have the pan concentrate fire assayed or refined. - Geowizard

    Prospecting 101

    Yes, BS detection is my expertise. I keep my BS detector turned "ON" at all times. Amazing amount of BS out there! That's why I started the thread "Prospecting 101". Learning any subject involves creating a "foundation" of understanding that supports further learning. BS causes cracks in the building of knowledge. It's a construction project! Forums like this provide an opportunity for personal learning. - Geowizard

    Uh... "acids" "Aqua-Regia", "Mercury", "cyanide". These are chemicals, right? Read it again. Might be time for new glasses. - Geowizard

    The other option is a still camera shooting video of a vibrating screen for an hour. A follow-up one hour segment with a camera zoomed in on a suction pump! - Geowizard

    Extremely Fine Gold Recovery

    I read very well, thank you. Gravity methods of recovery have a LIMIT. To separate smaller gold, more screening is required to maintain compatible particle size. Screening to smaller and smaller sizes becomes impractical at a certain point. The process of catching gold includes clean-up where micron gold in concentrates is most often lost! Flotation and digestion including amalgamation will increase recovery at the point where further screening is impossible. Go to the top and read the first post. - Geowizard

    Metal Detector Theory

    There are many other applications for metal detectors. Commercial metal detectors are used for security of entry-ways in many government buildings. - Geowizard

    Electro-Winning

    The process is technically "electrorefining". Electro-winning is a recovery process and not a refining process. There are many references on the subject. - Geowizard
