Modular Gold Beneficiation Plants Modular plants for extraction and recovery of gold are custom-designed for a specific application due to the characteristics of the gold bearing ore. Benefits of modular plants for gold beneficiation are: • Short construction times. • Low capital costs. • Easily movable.
The EXAMPLE Gold Mill is designed to process 500 tonnes per day of ore. The flowsheets are conventional and consist of two stages of crushing, single stage ball mill grinding, cyanidation and a Merrill-Crowe precipitation circuit for gold and silver recovery. In addition to the cyanide circuit, gold leach residue is treated in a flotation stage ...
The gold ore straight from the mine gets fed into a jaw crusher first. This big machine breaks down the huge rocks into smaller pieces, usually around 100-200 mm in size. After that, the crushed ore moves to the secondary crusher, which is usually a cone crusher. Here, it gets crushed even more, down to around 10-50 mm.
An endless chain of baskets brought this to the drying mill and the 480 magnets of the seven-story separator. Magnetic ore separation plant, Edison (now Ogdensburg), New Jersey, c. 1895. Courtesy of the U.S. Department of the Interior, National Park Service, Edison National Historic Site.
A year later Edison began applying for patents for electromagnetic separation of ores, having concluded that the magnetic portion could be made "into the very best iron equal to Swedish bars at a cost which makes it far more valuable than . . . the gold tailings."
