Gold is one of the first minerals used by prehistoric cultures. The Latin name for this mineral was aurum and Jns Jakob Berelius used Au to represent the element when he established the current system of chemical symbols. The Old English word gold first appeared in written form about 725 and may further have been derived from gehl or

Heap leaching a process by which metals such as gold and copper are recovered from ore has long been a method of choice in ore beneficiation with applications growing all the time.. While this process has proven to be efficient often chosen for its cost-effectiveness the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum
