Magnetic separation utilizes powerful magnets to pull out ferrous metal contaminants from a product line, trapping them against the face of the magnet and ensuring they cannot reenter the product stream The strength of the magnetic field means that continued product flow, no matter how rapid, will not be able to dislodge the ferrous material from where it has been initially Mercury in its organic form also biomagnifies in food webs The use of mercury for gold extraction has been responsible for widespread contamination of aquatic ecosystems and the practice continues unabated in many parts of the world Other sources, historic and present, include industrial processes, pulp bleaching, as well as combustion and release of natural Gold Extraction an overview ScienceDirect Topics29/02/2016 Amalgamation is used to recover relatively coarse gold and for this reason has been very important in gold recovery systems Cyanide acts too slowly on coarse gold, but readily dissolves fine gold Flotation concentration is not effective on coarse gold The small miners who wish to treat a small tonnage of high grade ore and want a quick return rather than Gold Extraction Recovery Processes
