gold ores and minerals gold ore types gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. refractory ores are defined as those that give low gold recoveries or give acceptable gold recoveries only
in heap leaching, coarsely crushed ore is piled up on an impermeable layer and cyanide solution sprinkled over the heap. the heap leach pad is constructed on a gentile slope so that the solutions percolate down and collect on the impermeable layer and then drain down slope into a collection pond. the heap leach method takes much longer and generally does not recover as high a percentage of the gold and silver in the ore…
