    Heap Mining Efficiently Leaches Lower Grade Gold From S

    Gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below Placers, quartz vein gold ores and oxidized ores Generally, placers, quartz vein gold ores and oxidized ores are free milling and gold can be recovered by gravity and or direct cyanide leaching.Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon in pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
