Scientists have developed a new method for detecting gold in the earth’s crust using X-rays. The technique, called Gamma Activation Analysis (GAA), involves bombarding rock samples with high-energy gamma rays, making even the smallest traces of gold visible to a highly sensitive detector. The GAA is about two to three times more effective than conventional methods, and experts estimate that it could bring in an additional half a billion dollars in profits each year. Previously, rock samples had to be heated to 1,200 degrees Celsius to separate the individual components before experts could determine the gold content. With the GAA, the gold content can be determined on-site within minutes.
The new method is a significant breakthrough in the search for gold, which is rare and difficult to find. The GAA works similarly to X-rays used in medical imaging, and it is expected to revolutionize the mining industry. The technique is already being modified to detect other metals such as lead, copper, silver, and tin. The device is also being made smaller and more compact, making it easier to use on-site.
The GAA is a game-changer for the mining industry, as it allows for faster and more accurate detection of gold and other metals. The technique is expected to increase profits significantly and reduce the time and cost of mining operations. The new method is a testament to the power of science and technology in solving complex problems and advancing human progress.
