Heap Leaching of Gold and Silver Ores -

01-01-2016  The operating cost plus debt service for a medium-sized mill (3000 t/d) is typically $39/t of ore treated, whereas the comparable cost for the heap is $19/t, equating to a differential operating cost plus debt service of $20/t for milling compared with heap leaching. Assuming a gold price of $40/g ($1244/oz), the differential cost would require the milling option to deliver an additional 0.5 g/t of payable gold from the extra 25% gold recovery compared with the heap leaching

Cyanidation of a pyrrhotite-bearing gold ore

water was used to pulp the ore. The gold-leaching cell is made of Limestone, with a capacity of two litres. The tests were performed on a pulp of 50% weight (1000g of ore with 1000ml of solution). Most of the cyanidation tests were carried out with a grind size at 73.9% -74µm and 100% passing 149µm. Table 1 Analysis of the pyrrhotite-gold ore

Alternative Lixiviants to Cyanide for Leaching

01-01-2016  Chlorine, bromine, and iodine are well-known lixiviants for leaching gold, as reviewed by Tran et al. (2001). Chlorination was applied extensively in the late 19th century before the introduction of the cyanidation process. Bromine/bromide for leaching gold from ores was reported as early as 1846.

Heap Mining Efficiently Leaches Lower Grade

As a rule of thumb, one gram per ton of ore can make a profitable heap leach mine. At a 75% gold recovery, it takes 41 tons of ore on the pad to recover one ounce of gold. However, all the material in the mine is not ore. Most mines will have 2-3 tons of waste material to 1 ton of ore. This waste must be taken to a separate dump.

gold ores. A refractory ore, generally, contains sulfide minerals, organic carbon, or both. Sulfide minerals (pyrite, pyrrhotite, or arsenopy-rite) often trap or occlude gold and other precious metal particles [4]. Organic carbon present in gold ore may adsorb dissolved gold cyanide complexesin muchthe sameway asactivated carbon (AC).
